As for fixed wing aircraft, if you are referring to something like the A-10 or Su-25, then it's a waste of money. The better option is to go for multirole fighter aircraft, and this is obviously the IAF's domain. The time of dedicated attack aircraft are over.
But 100 US supplied Avenger UCAVs will be joining the IAF's inventory in support of the IA's operations.
Since then, the IA has also expressed interest in procuring 120 Avengers for the AAC.
220 of these drones should comfortably take care of our needs over the next 15 years.
