The current in-game model of the L-39ZA does not represent the real-world version of the aircraft. It appears to be a hybrid between the L-39C and early ZA variant. However, if it is labeled as L-39ZA, it should have access to R-60 (or K-13/R-3S) missiles, and use the correct performance data from the AI-25TL engine.
EVIDENCE:
- R-60 and K-13 (R-3S) armament
Real L-39ZA aircraft were exported and used in combat with these missiles:
- Syria, Libya, and Angola used R-3S and R-60 on ZA platforms
- Czech/Slovak manuals and export brochures list compatibility with R-3S
- Some late-production ZAs even had basic RWR systems
- Engine performance discrepancy
The AI-25TL engine in-game:
- produces less than 16.9 kN static thrust
- results in underpowered climb rate and acceleration
- max speed is lower than real manuals indicate (~900–950 km/h clean at sea level)
Suggested Fixes:
- Allow R-3S or R-60 to be equipped (even as a researchable modification)
- Update engine performance to match AI-25TL specs (16.9 kN)
- If model is based on early ZA, rename to L-39ZA Early or L-39C mod.
