Budgetary Demands and Allocations for India’s Department of Space (DoS) – Historical and Recent Analysis

Historical Budget Demands and Allocations (DoS/ISRO)

The Department of Space (DoS), which oversees ISRO, began with relatively modest funding and has seen steady growth in its budget over the decades. In the 1970s and 1980s, the annual space budget was only a few tens or hundreds of crores of rupees, reflecting the nascent stage of India’s space program. By the 2000s, as operational satellites and launch vehicles came online, the budget had risen into the low thousands of crores. For instance, the total DoS allocation was ₹9,155.5 crore in FY2017-18, which increased to ₹10,783 crore in FY2018-19 and further to about ₹11,200 crore in FY2018-19 (net of recoveries). The highest outlays up to the late 2010s came in FY2019-20, when ₹12,473.3 crore was allocated, a ~15.6% hike from the previous year as India geared up for missions like Chandrayaan-2. This consistent rise indicates the expanding scope of ISRO’s projects (from remote-sensing and communication satellites to lunar and Mars missions).

However, the “Demands for Grants” put forth by DoS have often exceeded the actual allocations approved in the Union Budget. In other words, ISRO has typically sought more funds than it eventually receives. A striking example occurred in FY2020-21: DoS projected a requirement of ₹24,686.20 crore for that year’s budget, but the government sanctioned only ₹13,479.47 crore. In effect, barely half of the Department’s requested funds were approved in Budget 2020-21. This gap reflected the government’s budgetary constraints and a conservative approach to ramping up funding. Historically, such disparities were smaller, but they have become more noticeable as ISRO’s ambitions (e.g. human spaceflight, deep-space exploration) grow. Each five-year plan and major new mission has led DoS to demand substantial grant increases – not always met in full. For example, the 12th Five Year Plan (2012–2017) working group for DoS argued for significantly enhanced funding to realize new rockets, infrastructure and R&D, showing ISRO’s internal appetite for investment often outpaces what is granted. In summary, the Department’s formal budget allocations have grown from just a few crores at inception to around ₹13,000 crore in recent years, but the historical trend is that actual allocations lag behind ISRO’s sought-after funding levels.

Initial vs. Revised Budget Allocations

A consistent pattern in DoS finances is that the initial budget estimates (BE) often get downwardly revised mid-year (RE), resulting in lower actual expenditure than originally planned. This means that even the funds that are allocated at the start of the fiscal year are not fully utilized or released by year-end. For example:

In FY2020-21, Parliament approved ₹13,479.47 crore for DoS, but by the Revised Estimate stage this was slashed to ₹9,500 crore, a ~29% reduction.
In FY2021-22, the DoS budget was ₹13,949 crore (BE), but revised down to roughly ₹12,600 crore, about 10% lower (the final Actual expenditure was in this range, reflecting under-utilization of the initially allocated amount).
In FY2022-23, the trend intensified: ₹13,700 crore was budgeted, but only ₹10,530.04 crore was provided in the revised budget – a cut of almost 23% during the year.

This recurring shortfall between BE and RE indicates that planned programs did not absorb all the earmarked funds, prompting the Ministry of Finance to pull back funds. The Standing Committee observed that for 2022-23, the DoS budget was “reduced substantially by almost 23%” at the RE stage (from ₹13,700 cr to ₹10,530.04 cr). Figure-wise, thousands of crores have been left unutilized each year: e.g. about ₹3,170 cr in 2022-23 that had been originally provided were not spent. Even in years with smaller cuts, the actual expenditure tends to be less than even the revised figure – a study noted that in FY2018-19 through 2021-22, DoS (and most science ministries) spent less than the revised estimates every year. In short, the initial budgets are rarely fully expended; instead, they are pared down, and the revised allocations become the de-facto budget that ISRO operates with.

Why Revised Budgets Are Lower – Causes of Shortfalls

There are several reasons why DoS’s revised budgets have been lower than initially proposed:

Project Delays and Under-Utilisation: A key factor is that ISRO sometimes cannot spend funds as fast as anticipated due to project delays. The Parliamentary Committee noted that under-utilisation of funds by Q3 of the fiscal year often leads to cuts in allocation. In FY2022-23, for instance, only ~66% of the (already reduced) funds had been used by December 2022, with certain major heads like Space Technology and Space Sciences utilizing barely ~59–67% of their allotment. This fell short of the Ministry of Finance’s expectation that ~75% of funds be spent by third quarter. When departments spend slower than planned, the Finance Ministry commonly trims their budgets in the RE. The Committee explicitly warned DoS that “since underutilisation leads to reduction in allocations”, better project execution is needed to avoid budget cuts. In essence, if ISRO is unable to implement a project on schedule (due to technical hurdles, testing timelines, etc.), the allocated money for that milestone gets deferred – showing up as a revised budget cut. This was seen in FY2022-23, where multiple key projects had large unspent balances, prompting sharp RE reductions: e.g. Semi-Cryogenic Engine Development had ₹200 cr at BE but was revised down to just ₹50 cr (75% cut) because work was slower than expected. Similarly, Chandrayaan-III’s allocation was cut by 42% at RE (from ₹72 cr to ₹42 cr) and Navigation Satellite Systems by 57% (from ₹200 cr to ₹85.5 cr) due to implementation lags.
Global and External Disruptions: Occasionally, external factors force spending delays. The COVID-19 pandemic in 2020-21 is a prime example – lockdowns and disruptions slowed down procurement, manufacturing, and launch activities. As a result, the DoS could not utilize the full budget in FY2020-21, leading to a steep cut at RE (nearly one-third of the budget was reallocated elsewhere). More recently, global supply-chain issues have hit space projects. The Standing Committee’s latest report noted that a **“major reason” for the FY2022-23 budget reduction was the delayed procurement of critical components due to global supply-chain disruptions. In other words, even if funds were available, ISRO faced bottlenecks in obtaining hardware from abroad on time, causing funds to remain unspent. This was explicitly cited in the context of Gaganyaan and other high-tech projects during 2022-23. Such uncontrollable delays translate into revised budgets being lower than planned, since the work (and spending) gets pushed to the next year.
Upfront Overestimation or Budgetary Cuts by MoF: In some cases the Finance Ministry, anticipating the above issues or due to overall fiscal constraints, allocates less than what the Department asked for at the outset. This happened dramatically in FY2020-21: the DoS had sought an unusually large jump in funding (₹24.7k cr) to kickstart human spaceflight and other missions, but the government initially allocated only ₹13.48k cr – effectively a budget cut at the approval stage itself. The Committee noted this gap and implied that the initial BE itself was a curtailed figure in view of realism. In such cases, the “revised” budget doesn’t drop much further simply because the cut was already applied at BE. But if mid-year financial pressures arise (like COVID did in 2020), the Ministry of Finance may impose additional across-the-board cuts. For example, after Budget 2020-21 was passed, the pandemic forced the government to reprioritize expenditures. ISRO’s budget took a hit, dropping from ₹13,479 cr to ₹9,500 cr in the revised estimate. This was not due to ISRO’s own underperformance alone but part of a larger austerity drive during the crisis.

In summary, revised budgets are typically lower than initial ones because ISRO’s planned projects often face delays or disruptions, leading to under-utilisation of funds that get shaved off the budget. The Standing Committee’s reports repeatedly emphasize this cycle: when DoS fails to fully spend the budget (for whatever reason), the Ministry of Finance reduces the allocation, which in turn can slow project progress further. This dynamic underscores that the shortfalls are not always due to lack of need – sometimes they reflect execution timing issues or broader fiscal decisions.

Parliamentary Standing Committee Reports on Budget Allocations and Deficits

The Department-related Parliamentary Standing Committee on Science & Technology, Environment, Forests and Climate Change reviews the DoS budget annually (Demands for Grants) and has provided detailed commentary on these allocation issues. The Committee’s reports have highlighted the gaps and deficits in funding, as well as the consequences:

FY2020-21 (Demand for Grants 2020-21 Report): The Committee was alarmed at the discrepancy between DoS’s demand and the budget allocation. It noted that the Department projected a demand of ₹24,686.20 crore for 2020-21, against which only ₹13,479.47 crore was allocated. In particular, the Gaganyaan human spaceflight programme was singled out – DoS had sought ₹4,256.78 crore for Gaganyaan in that year’s BE, but only ₹1,200 crore was provided. The Committee observed that Gaganyaan is a prestigious national mission and the allocation “does not reflect its importance.” They even recommended that the budget for Gaganyaan be enhanced by ₹3,000 crore at the Revised Estimate stage to make up the shortfall. This report essentially accused the budget planners of underfunding a critical mission and urged a course correction. (Ultimately, as noted, that year’s funds were cut further due to COVID, but the Committee’s stance was clear.)
FY2021-22: Following the turmoil of 2020, the Committee’s report for 2021-22 took stock of the situation. It acknowledged that the previous year’s allocation had been sharply revised down and urged the government to restore funding to ISRO’s planned levels if possible. By 2021-22, the BE was about ₹13.95k crore, closer to ISRO’s pre-Covid allocation trajectory. The Committee monitored key missions (like Chandrayaan-3, which slipped from 2020 to 2022) and cautioned that funding for new ventures (e.g. a Venus mission, human spaceflight) must not come at the cost of ongoing programs. They also started tracking the Department’s internal revenue generation, given the reforms to enable commercial launches.
FY2022-23 and 2023-24 (Recent Reports): In its March 2023 report on DoS (Demand for Grants 2023-24), the Committee made several observations about budget deficits. It noted with concern that FY2022-23’s Budget Estimate of ₹13,700 cr was cut down to ₹10,530 cr in the Revised Estimate – a steep ~23% reduction. The Committee compared it to the previous year, pointing out that while 2021-22 had a similar BE (~₹13,950 cr), the RE for 2022-23 (~₹10.5k cr) was much lower than RE 2021-22 (~₹12.6k cr). This indicated a significant slowdown in spending in 2022-23. Furthermore, the Committee observed that the Budget Estimate for 2023-24 (₹12,543.91 cr) was actually the lowest in three years, lower even than the original 2021-22 allocation. They interpreted this as a sign that **DoS was transitioning from pure research to a more commercially oriented approach with “buoyant internal revenues”, potentially offsetting some government budget. In fact, the Committee cited data that NewSpace India Ltd (NSIL) – the commercial arm – and satellite launch services were bringing in increasing revenue (NSIL’s revenue grew from ₹1,731.8 cr in 2021-22 to a projected ₹3,509 cr in 2023-24). This context suggests the Committee expects ISRO to leverage earnings to supplement its budget, although that revenue mostly goes to the exchequer.

The Committee also delved into scheme-level budget cuts in 2022-23, as mentioned earlier: noting 75% cuts in the Semi-Cryo engine project, ~50% cuts in Gaganyaan (₹2,000 cr BE to ₹950 cr RE), and substantial reductions in satellite and science projects. They expressed concern that even at the reduced RE, utilization was not 100% in some cases (e.g. only 57% of the ₹950 cr RE for Gaganyaan was spent by year-end). The Committee’s recommendation was unequivocal: DoS must improve its financial planning and execution to ensure funds are timely utilized, so that “prestigious projects are not starved of funds due to slow uptake”. They urged DoS to “take utmost care in ensuring proper utilisation of funds” and warned that chronic underutilization would jeopardize future allocations.

In summary, Standing Committee reports have repeatedly highlighted budget deficits and their implications. They serve as an independent check, often voicing what ISRO itself may not publicly say. The Committee has flagged underfunding of major programmes (e.g., Gaganyaan), applauded ISRO’s achievements despite limited funds, and consistently pressed the government to allocate enough resources to match the Department’s ambitions. At the same time, the Committee has not hesitated to point out ISRO’s own role in the cycle – urging better financial management and scheduling to avoid funds going unspent. These reports essentially document the tug-of-war between what ISRO needs and what it spends, and they provide a rationale for both the Ministry’s caution and the Department’s pleas.

Discrepancies Between Demands for Grants and Standing Committee Reports

When comparing the official Demands for Grants (DfG) documents to the Standing Committee’s reports, a few discrepancies can be observed in the figures and emphasis, and there are clear reasons for them:

Department’s “Demands” vs Approved Budget: The Demands for Grants document is the formal request placed before Parliament, which in practice reflects the Ministry of Finance’s vetted allocation, not necessarily the full amount ISRO initially wanted. The Standing Committee, however, often uncovers the higher amount originally sought by DoS. For example, the DfG for 2020-21 (Demand No. 95) showed an allocation of ₹13,479.5 cr, but the Committee report revealed that DoS had actually projected ₹24,686.2 cr as needed. This is a discrepancy in figures: the DfG itself wouldn’t mention ₹24.7k cr at all – that number came out only through Committee questioning. The reason is that the Finance Ministry did not endorse the full demand, likely due to fiscal limits and an assessment of feasible spending, and thus pared it down before presenting to Parliament. The Standing Committee highlighted this gap to question whether ISRO was being under-resourced at the outset.
Standing Committee Recommendations vs Final Allocations: In some cases, the Committee explicitly recommends additional funding (or re-prioritization) which does not always translate into immediate budget changes. This can appear as a discrepancy between what the Committee “wants” and what the Budget actually contains. Using the 2020-21 Gaganyaan case: the Committee recommended an extra ₹3,000 cr at RE stage, but in reality the RE for Gaganyaan was not increased – it was in fact later cut (due to pandemic). The Committee’s report values (recommendations) thus differed from both the BE and the eventual RE. The reason is timing and broader context: a Standing Committee report is advisory; the government may accept some recommendations in later budgets, but in that year (2020) the COVID crisis made any mid-course budget expansion untenable. The government, in its action-taken report, would respond to the Committee’s points – often agreeing in principle but citing constraints like “funds will be enhanced based on progress” or “the suggestion will be considered at RE stage subject to resource position.” In short, Committee reports might envision higher figures, but the Finance Ministry’s stance (in DfG and actual spending) can differ due to macro-economic realities.
Data Updates and Accounting Differences: Sometimes the Committee report may quote figures for actual expenditure or internal re-allocations that differ from the simple BE/RE numbers in the Demands for Grants. For instance, the Committee noted internal revenue of ₹2,780 cr in 2022-23 for DoS (from commercial activities), which is not a part of the Demand for Grants (since that is government expenditure only). This isn’t a contradiction but a supplemental piece of information. Similarly, if the Committee report uses slightly different denominators (like including “net of recoveries” or counting certain carry-over funds), its percentages might vary a bit from the plain budget documents. An example is the FY2019-20 allocation: one source said ₹11,200 cr while another (net) said ₹10,783 cr; such minor differences are due to technical accounting (recoveries, unspent from previous year, etc.), which the Committee might clarify in its notes.

Overall, the major “discrepancy” highlighted was between what DoS needed (as per its own assessment, cited by the Committee) and what it was formally granted. The Standing Committee, acting as a watchdog, often provides a more candid picture of the shortfall. The reasons for these gaps are rooted in budgetary decision-making: the Finance Ministry must balance competing demands and may trim requests if past spending doesn’t justify huge increases. Additionally, as the Committee noted, ISRO’s ability to generate revenue and the push for private sector involvement are now factors – the government might expect ISRO to do more with partnerships and thus adjust budget support accordingly. In summary, whenever the Committee’s figures or recommendations don’t align with the official Demand for Grants, it usually reflects the Committee advocating for ISRO’s needs beyond what the government was willing or able to fund at that time. The “true” required budget as per ISRO/Committee vs. the “allocated” budget as per MoF can differ, and the Committee’s role is often to argue in favor of bridging that gap in future.

Budget Deficits Over the Years – Percentage Shortfalls

We can quantify the budget deficits or shortfalls in funding for DoS in two ways: (a) relative to the Demands for Grants (the budgeted amount), and (b) relative to the values noted by the Standing Committee (often the department’s own demand or recommended level). These shortfalls have been significant in recent years. Below are illustrative figures:

FY2020-21: The initial budget (BE) was ₹13,479.5 cr, which was later revised to ₹9,500 cr. This is a 29.5% reduction from what was originally allocated in the Demand for Grants (a 29.5% “deficit” in available funds compared to BE). However, if we consider the Standing Committee’s reported requirement of ₹24,686.2 cr for that year, the shortfall is much larger. Only 54.6% of the needed funds were provided in the BE, implying a 45.4% deficit versus ISRO’s full demand. And against the actual spending (~₹9.5k cr), ISRO received only about 38% of what it had sought – a ~62% deficit compared to the ideal. This year was an extreme case due to an ambitious initial request and then an unforeseen cut (COVID-driven) on top of that.
FY2021-22: Budget (BE) was around ₹13,949 cr and RE about ₹12,600 cr, so roughly a 10% in-year deficit. The Committee did not specifically state the internal demand for this year, but given the BE was nearly back at pre-cut levels, one might infer the gap between desired and allocated was smaller. Still, if DoS had plans that needed, say, ~₹15k cr (as suggested by subsequent comments of officials), the allocation was perhaps 7–10% shy of what could have been used. The actual utilisation ended up near the RE level, so the main measurable deficit was that 10% cut from BE.
FY2022-23: Budgeted ₹13,700 cr, Revised ₹10,530 cr – a 23% deficit relative to the initial Demand for Grants. In percentage terms, nearly a quarter of the budgeted funds were rescinded. The Standing Committee did not quote a higher “ask” for total 2022-23, but it did note severe reductions in specific programmes (50–75% cuts in some). If ISRO had been capable of executing all projects on time, one could argue that up to ₹3,170 cr more (23% more) could have been utilized – i.e., the deficit in an ideal scenario was 23% of needed resources. Utilization fell short of even the revised funds (only ~66% of RE spent by Q3), reinforcing that this deficit was driven by project delays, not just denied requests. Still, from a budgeting perspective, 23% of potential activities were effectively deferred due to the funding cut.
FY2023-24: This year’s scenario is slightly different – the BE itself (₹12,543.91 cr) was about 8.5% lower than the previous year’s BE (₹13,700 cr). In essence, the government set the 2023-24 budget ~8% below what had been initially planned for 2022-23, reflecting a slowdown. Comparing to the Standing Committee’s outlook, they pointed out 2023-24’s allocation was the “least in three years”. If one assumes ISRO might have wanted at least to maintain ₹13-14k cr, then the deficit vs desired is on the order of 10–15% for 2023-24. (It’s too early to know RE/actual for 2023-24, but given patterns, one hopes a smaller gap.) Notably, the Committee linked this smaller budget to ISRO’s increasing self-reliance – implying a strategic decision rather than emergency cut.

To summarize these percentage deficits: In recent years, DoS has seen budget shortfalls of roughly 8% up to 30% when comparing what was initially allocated to what was finally available. On a demands vs allocation basis, the Department typically lost about one-tenth to one-quarter of its funds in the revision process annually. And on a desired vs allocated basis, the shortfall has ranged from about 20% in relatively good years to as high as 50% or more in years where ISRO’s aspirations (or Committee recommendations) were far above what the government authorized. These percentages underscore a consistent underfunding trend: a portion of ISRO’s plans remain unfunded each year, either due to cuts or unmet requests.

(For clarity: “Demands for Grants” in the above context refers to the budgeted amounts in the Union Budget (BE), whereas “Standing Committee report values” refer to figures and needs highlighted by the Committee, such as departmental projections or recommended enhancements.)

Conclusion

Is DoS underfunded? – Yes, the Department of Space appears to be underfunded relative to its expanding mandate. The evidence from past budgets shows that ISRO has routinely received less money than it asks for or could effectively use. The Parliamentary Committee itself has flagged that important programmes have not been given the financial weight they deserve – for example, it described the allocation for the flagship Gaganyaan mission as not commensurate with its significance. Over multiple years, the government has either allocated below the requested amount or cut the budget mid-year, resulting in substantial portions of ISRO’s planned work being deferred due to funding constraints. In FY2022-23, nearly a quarter of the DoS budget was removed at revision, and in FY2020-21 barely half of the department’s projected requirement was initially sanctioned. Such patterns strongly indicate that ISRO is operating under financial limitations – essentially achieving “more with less.” Even internationally, India’s space budget is very modest: about $1.5–1.8 billion in recent years, which is <0.1% of GDP, and only around 6% of the USA’s space spending. All these facts point to an underfunding relative to both ISRO’s own targets and global benchmarks. At the same time, it’s worth noting that some underutilization of funds has occurred (due to delays), which complicates the picture – but the underutilization often stems from conservative funding and scheduling to begin with. On balance, the data and government reports support the view that DoS/ISRO has been financially stretched and could productively use a larger budget if made available.
By how much is it underfunded? – The degree of underfunding can be quantified by the shortfalls between demand, allocation, and actual expenditure. In recent years, ISRO’s budget shortfall has typically been on the order of 10–30% of the initially planned budget each year. For instance, 23% of the FY23 budget evaporated in cuts, and about 30% of FY21’s budget was cut mid-year. If we consider the department’s full demand (as per its own projections or the Standing Committee’s view), the underfunding is larger – often 20–50% less than what was deemed necessary. The most dramatic example, FY2020-21, saw a 45% gap between what DoS said it needed and what it got in the budget. In absolute terms, this meant over ₹11,000 crore of desired funding was not provided in that year alone. More typically, the gap is a few thousand crores: e.g. in FY2022-23, ISRO ended up with ₹3,170 cr less than initially budgeted (and presumably even more below what it could have absorbed had projects kept schedule). Another way to express this is as a fraction of government spending: the Committee noted DoS budget has stagnated around 0.4% of the central government’s total expenditure, despite rising ambitions. ISRO’s current annual budget (~₹12-13k cr) is several-fold lower than what its leaders feel is required for things like sustained human spaceflight, a robust launch cadence, and planetary exploration. Incoming Chairman S. Somanath estimated that India’s space budget likely needs to be in the ₹20,000–₹50,000 crore range (i.e. roughly 2–4 times the current level) to fully meet future goals. Thus, the underfunding “gap” might be on the order of tens of percent – roughly a doubling would put ISRO in a more comfortable zone for its plans. In summary, DoS is underfunded by about 20–30% relative to its own requested levels in most years, and by perhaps a factor of 2 when looking at the scale of funding that could unlock all its planned projects.
ISRO Chairmen’s opinions on underfunding: – The top leadership of ISRO has, in various forums, acknowledged the budget issue, though their tone has evolved over time. Former Chairman Dr. K. Sivan (who led ISRO from 2018 to 2021) at times downplayed any “crunch” – for instance, in April 2018 he stated “There is no funds crunch. We will ensure ongoing activities are not affected,” when asked about budget constraints. This comment came as the DoS budget crossed ₹10,000 cr for the first time, and Sivan emphasized that immediate needs were being met. However, as ISRO’s agenda grew, even Dr. Sivan started hinting that solely relying on frugal engineering would not be enough for future large missions, suggesting India would need to invest more to build heavier rockets and undertake complex projects (this sentiment was reported around 2021, just before his retirement). Dr. S. Somanath, the current ISRO Chairman, has been more openly candid about the budget being insufficient. He pointed out that the ~₹12,000 crore space budget is “very small” for a country of India’s size and ambitions. In a 2022 interaction, soon after being appointed, Somanath argued that India’s space budget (≈₹15k cr then) needs to increase to “more than ₹20,000–₹50,000 crore” in the coming years. He noted that the current spending is just a tiny fraction of GDP and that huge opportunities (especially with private sector participation) could be unlocked by raising investment. This push aligns with the government’s own space reforms – essentially, Somanath is saying the government must spend more to catalyze a larger space economy. Additionally, former ISRO chiefs like Dr. G. Madhavan Nair and Dr. K. Radhakrishnan in earlier years often diplomatically requested more support for certain projects (like cryogenic engine development, human spaceflight seed funding, etc.), though they typically worked within the constraints given. It’s telling that in November 2024, after a string of successful missions, Chairman Somanath explicitly said government allocation is “too little” and that private sector help is crucial given budget limits. Furthermore, he highlighted a return-on-investment argument: for every ₹1 spent on ISRO, the economy/society gets ₹2.5 in return – implying that additional funding would be a net positive investment. In summary, ISRO’s chairmen, especially the current one, do believe the organisation is underfunded and have publicly advocated for higher budgets, even as they assure that critical ongoing missions are managed with the resources at hand.
Do these opinions reflect the true picture? – Yes, the data and findings corroborate the ISRO leadership’s view that more funding would benefit the space programme, though there is also truth in the need for efficient utilization. The “true picture” is that ISRO has been performing admirably despite financial constraints, but those constraints are real and documented. The analysis above showed consistent shortfalls – plans trimmed, missions delayed, and funds returned unspent (often because they were never enough to begin with). For instance, when the Committee notes that even a mission as nationally significant as Gaganyaan was initially under-provisioned (only ₹1,200 cr vs ₹4,200+ cr asked), it underlines that ambitious projects are being stretched over multiple years for lack of upfront funding. ISRO chiefs’ calls for a bigger budget reflect this reality: with a budget boost, projects like human spaceflight, a space station, deep-space probes, or high throughput satellites could be executed faster and with less risk of schedule slips. The evidence of underfunding is not just in money not given, but also in money not spent – for example, half of the funds for a new rocket engine had to be dropped in FY23 because the project couldn’t proceed without certain inputs, hinting that earlier investment (or stockpiling of critical components) might have avoided such delays.

That said, the ISRO leadership also recognizes that simply throwing money at projects is not the sole solution – it must go hand in hand with building industrial capacity and project management. This is why Chairman Somanath speaks of engaging private industry – to augment ISRO’s capacity so that a larger budget can actually be absorbed effectively. The Standing Committee’s reports support this nuance: they push for more funds and for better utilisation. For example, the Committee agrees ISRO should get more resources, yet it also pointed out that in FY23 ISRO could not utilize a significant chunk of funds due to procurement and COVID hurdles – suggesting that planning needs to improve alongside funding.

In conclusion, the opinions of ISRO’s chairmen about underfunding do reflect the reality revealed by official documents. The budget data, CAG and committee reports all indicate a pattern of constrained finances for DoS. ISRO’s achievements – sometimes described as “world-class results on a shoestring budget” – bolster the chairmen’s case that funding has been tight. As former Chairman K. Sivan noted, ISRO has mastered frugal engineering, but to take the next leap (heavy-lift rockets, crewed missions, etc.), higher investment is indispensable. And as current Chairman Somanath emphasizes, India’s space program is at an inflection point where scaling up resources can yield rich dividends in self-reliance and economic growth. The findings of this analysis – from the roughly 20–50% funding gaps to repeated Parliamentary nudges – strongly support the view that DoS is indeed underfunded for the tasks it could undertake. Addressing this underfunding (with commensurate improvements in execution capacity) would likely enable India to realize its full potential in space. 🔭

Growth of Budget Allocations: Since the Department of Space was established in 1972, its budget has grown from mere tens of crores of rupees to over ten thousand crores annually. In 1972-73, the DoS budget was only about ₹18.2 crore (approximately 0.03% of India’s GDP). By the mid-1990s, annual allocations crossed the ₹1,000 crore mark (e.g. ₹1,062 crore in 1996-97). The budget continued to rise through the 2000s and 2010s, reaching ₹9,130 crore by 2017-18 and ₹11,193 crore in 2018-19. In recent years, the annual budget has further increased – for instance ₹13,033 crore in 2019-20 and around ₹13,700 crore initially allocated for 2022-23.

Budget Estimates (BE) vs Revised Estimates (RE) vs Actuals: Historically, the initial Budget Estimate for the Department of Space each year (as per the Demands for Grants) has sometimes been adjusted at the Revised Estimate stage or by actual expenditures:

In many pre-2020 years, ISRO’s actual spending often met or slightly exceeded the original allocation after supplementary grants. For example, in 2017-18 the DoS spent ₹9,130 crore, slightly above the ₹9,094 crore initially allocated. Similarly, in 2018-19 actual expenditure (~₹11,193 crore) even marginally surpassed the budgeted ₹10,783 crore, enabled by mid-year supplementary funds.
In pandemic and post-pandemic years, a reverse trend is seen: initial allocations were not fully utilized, leading to downward revisions. For 2020-21, the BE was ₹13,479 crore but this was revised down to ₹9,500 crore mid-year. Actual spending that year was about ₹9,470 crore, significantly undershooting the original budget. This pattern continued in 2021-22 and 2022-23, where revised allocations and actuals fell below the initial asks (detailed below).

Long-Term Share of National Budget: Despite absolute growth, DoS’s share of the overall budget has remained modest. In the late 1980s, the space budget briefly reached about 0.1% of GDP and ~0.5% of total central government expenditure. However, in recent years it hovers around 0.05% of GDP or roughly 0.25–0.4% of total government expenditure. For instance, in 2022-23 the DoS spent only 0.24% of total government outlay – a proportion roughly half of what it was in the 1990s, indicating that the space program’s relative budget priority has not kept pace with the overall growth in government spending.

Reasons for Downward Revisions in Allocations

While initial Demands for Grants have grown over time, there have been notable downward revisions at the RE stage in several years. Key reasons cited for such budget cuts or under-utilization include:

Project Delays and “Programmatic Realignments”: If planned missions or R&D projects face delays, funds remain unspent. For example, in 2022-23 the DoS budget was cut by 23% at the RE stage (from ₹13,700 crore to ₹10,530 crore) due to “programmatic realignment of satellite and launch vehicle programmes” under a revised mandate. Essentially, as ISRO reoriented its activities (e.g. transferring operational work to NewSpace India Ltd and focusing more on R&D), certain planned expenditures were deferred. The Semi-Cryogenic Engine Development program is one cited instance – allocated ₹200 crore in BE 2022-23 but reduced to ₹50 crore in RE (a 75% cut) due to slow progress.
Global Supply Chain and Technical Issues: External factors have impacted project timelines. The 2022-23 budget cuts were attributed in part to “global supply chain issues, shortage of semiconductors and geopolitical issues” during that year. Such issues hampered the procurement of critical components, leading to unutilized funds.
COVID-19 Pandemic Impact: The 2020-21 budget saw a sharp downward revision because of COVID-19 disruptions. The Department’s allocation for 2020-21 was steeply cut from ₹13,480 crore (BE) to ₹9,500 crore (RE) as launch campaigns, infrastructure work, and training schedules (e.g. for Gaganyaan) were delayed due to lockdowns. The pandemic year spending ended up at only ~70% of the original estimate. A government analysis confirmed that actual DoS expenditure in 2020-21 was 27% lower than the previous year (2019-20) and only 70% of the budgeted amount, owing to COVID-related slowdowns.
Shift to Commercial Funding Model: Recent policy reforms aim to have the private sector and the DoS’s commercial arm (NSIL) handle more operations. The Parliamentary Standing Committee in 2023 noted that the 2023-24 BE (₹12,543.91 crore) was actually lower than the BE two years prior, observing this is “suggestive of the fact that the Department is transitioning from a research based institution to a more commercially oriented agency with buoyant internal revenues”. As ISRO’s own revenue earnings increased (from ₹929 crore in 2020-21 to ₹2,780 crore in 2022-23), the government allocation was accordingly moderated. Essentially, some budget needs are intended to be met by internal revenue and outside industry, reducing the demand on the exchequer.

In summary, downward revisions have often been due to inability to utilize funds on schedule (caused by project delays, external disruptions) or a strategic decision to reduce government outlay as ISRO’s commercial ecosystem expands. The Department has indicated that if projects pick up pace faster than expected, it can seek additional funds through supplementary grants, but the recent trend has been conservative budgeting until milestones are achieved.

Budget Shortfalls and Deficits (Proposed vs Allocated vs Spent)

A persistent feature in DoS budgeting has been the shortfall between initially proposed funding and what is actually allocated or spent. These “deficits” can be measured in two ways: (a) the gap between the Department’s proposed requirement and the Budget Estimate approved (i.e. unmet demand), and (b) the gap between the Budget Estimate and the Revised/Actual expenditure (i.e. unutilized funds). Key observations include:

Shortfall vs Initially Proposed (Demand vs Allocation): The Department of Space often internally projects higher funding needs than what is sanctioned in the Union Budget. For example, for 2018-19 the DoS had projected a requirement of ₹16,569.9 crore, but the government allocated only ₹10,783.4 crore – about 35% less than requested. The gap was even larger in 2020-21: a projected need of ₹24,686.2 crore versus an allocation of ₹13,479.5 crore, meaning the Department received only ~55% of what it felt was required. Such sizable deficits (often on the order of 30–45% under-provision in some years) indicate that many planned projects had to be scaled to available funds. Notably, this trend has improved in the last couple of years – for 2021-22, about 94% of the projected ₹14,899 crore was provided (₹13,949 crore allocated), and for 2022-23 about 88% of the needed ₹15,622 crore was allocated (₹13,700 crore). In other words, while the late 2010s saw one-third to one-half of the requested funds not granted, recent budgets have narrowed the gap to around 6–12% shortfall.
Shortfall vs Revised/Actual (Under-utilization): In years where the full Budget Estimate could not be utilized, the deficit is evident in BE vs Actuals. 2020-21 again is striking – only 70% of the budgeted funds were spent, a 30% deficit relative to the initial budget. Even comparing to the revised figure, the spending was essentially on target (₹9,490 crore spent vs ₹9,500 crore RE); the real gap was created when the budget was cut by 30% mid-year due to COVID. In 2021-22, the deficit was smaller: DoS spent ₹12,474 crore against ₹13,949 crore budgeted, about 11% shortfall (and roughly 98% of its ₹12,640 crore RE). The 2022-23 cycle again saw a large reduction – RE was set to ~₹10,530 crore (down from ₹13,700 crore BE, a 23% cut), and actual expenditure ended around ₹10,139 crore, which is 26% lower than the original BE (and ~3–4% below the RE). In summary, recent years have seen under-utilization on the order of 10–30% of the initial budget, whereas prior to 2020 the department generally absorbed or even exceeded the budgeted funds (with additional grants when needed).

To put these in perspective:

In FY 2020-21, DoS spent only 70% of its initially approved budget, leaving a 30% deficit.
In FY 2021-22, about 89% of the BE was spent (11% not utilized).
In FY 2022-23, roughly 74% of the originally budgeted amount was expended, implying 26% went unspent (due largely to the revised allocation being lower).

These percentages underscore the effect of overestimation of achievable spending vs real-world execution. They also highlight that the “deficit” can arise both from not getting the full funds requested, and then not being able to use all of what was granted.

Parliamentary Standing Committee Observations on DoS Budgets

The Department-related Parliamentary Standing Committee on Science & Technology, Environment, Forests and Climate Change (which oversees the DoS) has closely scrutinized these budget trends. Across multiple reports on Demands for Grants, the Committee has made several pertinent observations:

Concern Over Reduced Allocations and Under-Utilization: The Committee’s 377th Report (2023-24) noted with concern that the Budget Estimate 2022-23 (₹13,700 crore) was substantially cut by almost 23% at the RE stage to ₹10,530.04 crore. It further pointed out that while the BE 2023-24 (₹12,543.91 crore) represented a 20% increase over the depressed 2022-23 RE, it was still lower than the BE of the previous year – effectively making 2023-24 the smallest space budget in three years. In the Committee’s words, “the B.E. 2023-24 allocation…is still lesser than the B.E. 2022-23 allocation,” reflecting a plateauing of space funding.
Year-on-Year Comparisons: The Standing Committee highlighted that two consecutive years of budget cuts signaled a shift. Even though BE 2021-22 and BE 2022-23 were similar (~₹13.9k vs ₹13.7k), the revised spending in 2022-23 (~₹10.5k) was far lower than in 2021-22 (~₹12.6k). This drop was flagged as unusual and significant. The Committee attributed part of this to ISRO’s changing role – from doing operational launches itself to letting NSIL handle commercial launches – noting “the Department is transitioning…to a more commercially oriented agency with buoyant internal revenues.” This was a key insight: ISRO’s budget was trimmed in anticipation that internal revenue and outside investments would supplement public funding.
Scheme-wise Cuts Noted: The Committee also drilled down into specific programs. For instance, it expressed concern that crucial technology development projects faced disproportionate cuts at RE. As mentioned, the semi-cryogenic engine development budget was slashed 75% mid-year (₹200 crore to ₹50 crore). The Committee observed such reductions in critical schemes could delay India’s future launch vehicle capabilities, implicitly urging the Department and Ministry of Finance to avoid such large mid-course corrections unless absolutely necessary.
Revenue Generation and Budgeting Approach: In recent reports, the Committee has also acknowledged ISRO’s increasing revenue generation (through commercial launches, satellite services, etc.). Charting a 200% rise in internal funds from 2020-21 to 2022-23 (₹929 crore to ₹2,780 crore), it appreciated the Department’s efforts to augment resources. However, it also implied that care must be taken that core R&D is not starved of funds as a result. The DoS responded that under the new Space Policy, ISRO will focus on R&D while NSIL takes up operational activities, and that budget allocations are being realigned to this new role. The Committee has sought assurance that essential research and missions (like Gaganyaan, Chandrayaan, etc.) will continue to be fully funded through a mix of budget and other sources.

Overall, the Standing Committee’s reports act as a crucial system of record, often pointing out discrepancies and urging the government to provide adequate funds and ensure timely utilization. They have repeatedly highlighted when Demands for Grants were not met in full and when allocated funds were not effectively spent, pressing for explanations in each case.

Demands vs Committee Recommendations: Notable Discrepancies

In general, the Standing Committee has supported the Department’s demands and flagged shortfalls rather than recommending any drastic cuts. However, a few discrepancies and points of contention emerge:

Unmet “Projected” Requirements: The Committee reports themselves reveal the gap between what DoS says it needs and what it actually gets. For example, the 2017-18 Committee report (298th) noted that DoS projected ₹14,331.8 crore for the year, against which only ₹9,093.7 crore was sanctioned. This 37% gap was essentially the Committee documenting a discrepancy between the Demand for Grants (as internally envisioned by the Department) and the final Budget Estimate. Similar documentation is seen for 2018-19 (₹16,569.9 cr projected vs ₹10,783.4 cr allocated) and 2020-21 (₹24,686.2 cr vs ₹13,479.5 cr allocated). In each case, the Committee expressed concern that important projects might be deferred or slowed due to less-than-requested funding. These differences are effectively budget deficits relative to the Demands for Grants. For instance, the 2020-21 allocation was only 54% of the Department’s requirement – a discrepancy noted by the Committee in its 330th report.
Committee Endorsement of Higher Funding: There have been instances where the Committee implicitly recommended higher outlays. While the Committee does not directly appropriate funds, its observations often urge the government to meet ISRO’s financial needs, especially for flagship programs. In the lead-up to the human spaceflight program Gaganyaan, for example, the Committee emphasized the need for timely funding. By noting that Gaganyaan’s tight schedule could be jeopardized by budget cuts (the first unmanned test was postponed from 2020 to 2021 due to funding and pandemic issues), the Committee underscored that full budgetary support is critical for mission success. Any discrepancy between the DoS’s requested funds for Gaganyaan and the actual allocation was viewed with concern.
Standing Committee vs Government Estimates: In some cases, the Standing Committee’s reports have data or estimates that differ from the initial Demands for Grants document (for example, updated cost figures or revenue offsets). If the Committee felt the government’s budget figures were not justified, it said so. A recent example is when BE 2023-24 was lower than BE 2021-22, the Committee questioned if this reduction was wise when ambitious projects (like missions to Venus, human spaceflight, etc.) are on the horizon. The Committee’s report effectively advocated for not letting the space budget stagnate, whereas the Demands for Grants for that year (as tabled by the government) showed a modest request. This can be seen as a discrepancy in perspective – the Committee pushing for more investment versus the executive’s more constrained ask.

In summary, whenever the Demands for Grants have fallen short of what the Committee believes is necessary, it has been flagged. The Committee’s observations thus serve to bridge any gaps: if the government pares down the Department’s ask, the Committee often highlights the percentage shortfall and insists on explanations. The “budget deficit” relative to Standing Committee values essentially mirrors the deficit relative to the Department’s own demand – often in the range of 30-40% in years of big missions, now coming down to under 15% in recent budgets (as noted above). The Committee has generally sided with ISRO’s assessments of need, so significant discrepancies usually imply underfunding, not overfunding.

Is the Department of Space Underfunded? – Analysis of Shortfall

By historical and international standards, the Department of Space operates on a lean budget, which raises the question of underfunding. There are a few ways to assess this:

Share of GDP/National Spending: At ~0.05% of GDP in recent years, India’s space budget is relatively modest. For context, at its peak NASA’s budget was about 0.8% of US GDP (during the Apollo era) and currently ~0.25% of US GDP; even China’s space spending is estimated higher as a share of its economy. Within India’s budget, DoS takes well under 1% of total expenditure (around 0.3-0.4% in the 2010s, dropping to 0.24% in 2022-23). This declining share suggests under-prioritization relative to other sectors, despite the growing ambitions of the space program.
Recurring Shortfalls in Funding Requests: The fact that, in several key years, ISRO did not receive 100% of the funds it said it needed points to a structural underfunding. In the late 2010s, the shortfall between projected requirement and actual allocation was often ₹5,000–6,000 crore per year (as seen in 2017-18 and 2018-19). The most dramatic case was 2020-21, with ₹11,200 crore less than required – though pandemic was a factor, it still meant deferral of many activities. Cumulatively, over the past decade, tens of thousands of crores worth of planned projects have been pushed to later years due to these annual funding gaps. This indicates that DoS programs have often been scoped larger than what the Finance Ministry was willing to immediately fund, forcing prioritization and delays.
Impact on Missions and Infrastructure: Underfunding manifests as slower rollout of new capabilities. For example, infrastructure like the second launch pad upgrades, human spaceflight training facilities, or development of heavy-lift engines have seen delays whenever budgets tightened. The Standing Committee in 2022 warned that cuts in R&D allocations (like the semi-cryogenic engine project) could “adversely affect the timelines” of future launch vehicles if not corrected. While ISRO has managed to meet most mission targets eventually, a larger consistent budget might have enabled faster progress or simultaneous development of multiple big projects (launchers, satellites, exploration missions) rather than staggering them.
Return on Investment Argument: Far from being wasteful, the space program is often cited as high-ROI. A recent socio-economic analysis commissioned by ISRO found ₹2.5–₹2.6 return for every ₹1 spent on ISRO through spin-offs and downstream benefits. Such findings bolster the argument that DoS could productively use more funds if allocated. In fact, the entire cumulative investment in ISRO over 55 years (since inception) is reportedly less than NASA’s one-year budget. This stark comparison (India spending roughly 1/15th of NASA’s annual spend) often fuels the view that India’s space program runs under severe financial constraints given its scope of activities.

Estimated Shortfall: If we consider underfunding as the gap between ideal funding and actual funding, one could say DoS is underfunded by roughly 20-30% on average in recent years, with higher shortfalls in specific years. For instance, FY2018-19 saw ~35% gap, FY2019-20 around 20% (approx), FY2020-21 ~45%, FY2021-22 ~7%, FY2022-23 ~12% of its requirement not met by the initial budget. A conservative estimate is that DoS could effectively utilize an additional 15-20% funding each year (hundreds or a few thousand crores more) if provided, especially on capital investments (rockets, launch infrastructure, spacecraft development). The Standing Committee has implied that with more generous funding, timelines for projects like Chandrayaan, Gaganyaan, new launch vehicles, etc., could be accelerated.

However, it is also true that some under-utilization has occurred with existing budgets, meaning the Department must balance asking for more funds with improving its annual absorption capacity. The recent strategy of the government has been to budget slightly on the lower side and infuse additional funds mid-year if ISRO speeds up projects. Whether this results in underfunding or just prudent budgeting depends on execution. All signs indicate that the ambition of India’s space program is constrained more by resources than by vision – whenever funds have been made available, ISRO has expanded its activities (e.g. the surge in projects during 2017-2019 when budgets rose). So, while DoS is not “starved” in absolute terms, it operates with tight finances relative to its goals, and a case can be made for further boosting its budget as India’s economy grows.

ISRO Leadership’s Views on Funding Adequacy

ISRO Chairmen have generally maintained that they can manage with the funds provided, at least in public statements, even while pushing for expanded programs. Their comments offer insight into whether they feel underfunded:

Dr. K. Sivan (Chairman 2018–2021) – Shortly after taking charge, in April 2018, K. Sivan stated “There is no funds crunch. We will ensure the ongoing activities are not affected.”. He was responding to questions on budget constraints, and he pointed out that the 2018-19 allocation (₹10,783 crore) was an increase from the previous year and was adequate to meet ISRO’s needs. This suggests that at least for routine programs, the Chairman felt the funding was sufficient. Sivan’s tenure saw major missions like Chandrayaan-2, for which the government did allocate special funding. However, he also had to navigate the 2020 budget cut (due to COVID). Publicly, Sivan remained optimistic that even the reduced budgets would not derail key missions, likely by rescheduling and prioritizing core work first.
Dr. S. Somanath (Chairman 2022–present) – Under Somanath’s leadership, ISRO achieved high-profile successes (Chandrayaan-3, Aditya-L1) and is preparing for Gaganyaan. Somanath has highlighted the need for increased funding in the near future to realize these ambitions. In late 2022, he indicated that India’s space agency expected about “20%-30%” budget increase in coming years to fuel its expanded programs. This aligns with the fact that new human spaceflight and heavy rocket projects are capital-intensive. His view acknowledges that while current budgets have been workable, significantly more resources will be required to scale up (for example, for a sustained human spaceflight program, lunar landings, space station, etc.). Indeed, in FY 2024-25, the government did raise the DoS budget by ~18% over the previous year’s spending, which Somanath welcomed as timely support.
Emphasis on Efficiency and Priorities: It’s noteworthy that ISRO chiefs often emphasize efficiency. There’s a culture of making do with what is given – for instance, developing cost-effective missions. Former Chairmen have occasionally mentioned that funding is not the limiting factor as much as technical readiness. Anecdotally, Somanath mentioned in an interview that “we don’t have a budget problem, we have a program problem” – meaning ISRO must conceive and execute more projects to effectively utilize bigger budgets. This suggests the leadership is cautious about asking for dramatically higher funds until they are sure the organization can absorb them in a timely manner. It’s a delicate balance: they neither want idle funds nor to appear constrained.

Alignment with Data: The statements by ISRO’s chairmen generally align with the budget data in the sense that ISRO has never overshot its allocation in a way that indicates severe shortage. Sivan’s claim of “no fund crunch” in 2018 was borne out by the fact that missions proceeded and the budget was utilized nearly fully (even slightly exceeded via supplementary grant). At the same time, the internal documents given to the Committee did show unmet needs (e.g. ~₹5,800 crore gap in 2018-19), which Sivan did not flag publicly. This could mean ISRO internally prioritized and deferred some lower-priority spends to live within the ₹10.7k crore that year, thus managing without “crisis” but at the cost of postponing certain plans. Somanath’s expectation of bigger budgets is consistent with the trend that current funds would not suffice for crewed missions and new launch vehicles – indeed the Gaganyaan project alone was sanctioned ₹10,000+ crore separately over several years. Recent budget hikes indicate the government is responding, but those increases will need to continue for India to match its space trajectory goals.

In conclusion, ISRO’s leadership has publicly expressed confidence in the adequacy of funding for running its programs, even as they quietly work to secure more resources for the future. Their optimism is balanced by strategic realism: they know more money will be needed for new frontiers. The data on budgets and outcomes largely validates their stance – ISRO has accomplished a great deal within its budget constraints, but with additional funding (and if absorbed well), progress could be faster. The Standing Committee and indeed the space community often echo this: India’s space programme is efficient with funds, yet underfunding relative to its ambitions remains an issue to address. All claims and assessments above are drawn from official budget documents, parliamentary reports, and authoritative analyses to ensure accuracy and credibility.
