Su-25, GSH-30-2

[TheTanner]

In the game, the Su-25 GSH-30 has an armor-piercing belt. It is not always convenient and is not suitable for half of the tasks of the Su-25. I suggest: either replace the current AP tape with a mixed one, or add a selection of tapes. High-explosive fragmentation shells, armor-piercing and without tracers.

В игре, у ГШ-30-2 на Су-25 только одна лента - БП. Она не удобна для половины выполняемых грачом задач. Я предлагаю заменить ленту на смешанную. Либо ввести возможность выбора лент, как на Ми-24П.

And the Su-25 with its 30mm shoots at a much shorter range than the same A-10.

А еще Су-25 своими 30мм стреляет на значительно меньшую дальность, чем тот же А-10.

A-10 GAU-8 fires much more powerfull AP cardridge 30x173 with 425 gram 1010m/s muzzle velocity when Su-25 GSh-30-2 uses far more moderate 30x165 with 390 gram 870m/s muzzle velocity.

Very nice that you found this data. Now let`s try to calculate energy difference between 2 bullets:

E=(mv^2)/2   or (0.425*1010^2)/2 for GAU-8   and  (390*980^2)/2  for GSh 30

(0.425*1010^2)/2=216 771 ; (390*980^2)/2=187 278

187 278/216 771=0.86 or 86%

GAU-8 max range=5km, so GSh 30 max range must be 5*0.86=4.3km.

Now we not have this range in DCS.

You've used wrong velocity for the GSh-30-2, probably just a mistake, it should be 870m/s. GSh-30-2 has 68% energy of GAU-8.

Wiki says 940m/s for GSh-30-2
