Zlins are so slow moving. They just need a better surveillance system, and then you can send anything after them. But indeed better base security would also fix this problem. SAM? No need, just a network of spotters with some well placed unguided fast-firing AAA will do. Better to spend it on night vision equipment or search lights, lol.
I'm not even sure the MiG-29's radar they are getting is capable to pick up such a slow moving, small, low-flying target because of the ground clutter.
The 30mm cannon is an interesting weapon to strafe targets though.
Indeed prop-powered Pucara or Bronco or the single-prop COIN aircraft would be a better option. Su-25 or A-37 would be the only sensible jet options, imho, but then they can't rely on the IAF to support them. The Chinese and Indians just havent got a proper COIN platform to offer them. But maybe even some armed helicopters would be fine.
I give it five years before all MiG-29s are grounded for lack of spares/maintenance/fuel/pilots/usuability... if the deal will happen. Let's first see about that.
What kind of radar does the IA-58 Pucaras's have could they track aircraft?
Two pair of human eyes, lol. As far as I know, they don't even have weather or collision aviodance radar.
