 By some estimates, the cost of destroying these resources would be higher than the projected cost of continuing Su-22 operations.It was decided that starting from 2015, only 12 Su-22M4 and 4-6 Su-22UM3K out of 32 remaining would undergo a refit, increasing their lifespan for another ten years.For economical reasons the aircraft are not modernized, apart from fitting an additional radio RS-6113-2 C2M with a blade antenna on the top, but they receive a new grey multishade camouflage, similar to other Polish aircraft.
