Yes, AA was engaged, and it looked like there were direct hits.
First 2 in the middle of the fuselage and for the third I slewed the shkval to the root of the back rotor hoping to hit a more critical point (later I read in this forum that since the damage model is not so detailed, hit placement would be rather irrelevant). Unfortunately I have no track to share and analise but I have seen the same behaviour with other choppers as well, even lighter helos.
Still in topic (I think), I tried to bring down an A-10 with the missiles. I set a training mission with one A-10 flying a rectangular pattern at 500 km/h and 1000 metres altitude and I placed my Ka-50 about 5 km from the pattern. After soooo much work I managed to lock the A-10 and shot my 12 missiles at it, with different aspect ratios, at varying distances and the result was always the same. Missiles leave the chopper tracking the target but after 300 or 400 metres, they just go ballistic, missing the target by far. AA mode was selected, AA/HO selected in some cases when relevant (however I think it only afects the fuse timing). It looks like that the missile was unable to follow the laser beam. Note that the shkval never lost track of the target aircraft.
What's your experience engaging fixed wing aircraft and bringing them down with vikhrs?
