Currently I'm working on the tuning of the missile behavior.
It should perform within 1% of the real shooting range data In the next version, you will have the possibility to choose between the V-755 (Guideline Mod.3) and the V-759 (Guideline Mod.5) missile.
The later (more advanced version) has lower speed and range, but better overload capability.
It become available to WarPact around 1983.
