Erm hate to break it to you but the AK's take 6 hits to sink a perry they do 23% per hit, they used to take 2 now it's almost double that, rough tacview here but everytime since then it always takes 6, 4 to disable, 6 to sink.
I can recheck tonight but from mp and other flights perry's always take 6 now. Tacview-20200304-205831-DCS.zip (1).zip
