FDI gun fits, order totals, and French program cost

The French and Greek versions use the OTO Melara 76 mm gun, while Sweden keeps its Bofors tradition with 57 mm and 40 mm weapons. The plans recalled here total five French, four Greek, and four Swedish ships. That produces only 13 hulls despite the design's export success, a total considered too small in this assessment. The five-ship French program is estimated at about 3.5 billion euros including development, or roughly 700 million euros per ship in 2025 money. Construction accounts for 2.1 billion euros and development for 1.4 billion, so comparisons need to separate recurring hull cost from one-time design expense. Sweden's Luleå variant includes substantial changes and should be treated as a modified design when comparing its cost and capability with the French baseline.
