That's most likely the FP-5 "Flamingo" cruise missile, a long-range weapon developed by the Ukrainian defense firm Fire Point. It has attracted attention primarily because of its significantly lower cost compared to similar Western missiles, a principle known as "affordable mass."
Here are the key details about the Flamingo:
- Low Cost: The estimated unit cost for the Flamingo is around $500,000 to under €1 million ($1.09 million) per unit, which is substantially less than the $1.5 million to $2.5 million cost of an American Tomahawk cruise missile [Source 1.2, 3.1].
- Design for Affordability: The lower cost is achieved through simplified design choices, including:
- Using repurposed Soviet-era AI-25TL turbofan engines (originally for L-39 trainer jets) [Source 1.2, 1.5, 3.3].
- A primary fuselage constructed from carbon fiber to keep costs down and aid in evading Russian radar [Source 1.1].
- Relying on a simpler GPS/GNSS and Inertial Navigation System (INS) rather
