Keep hearing a total fleet of circa 100 plus a sustainment margin, the size of which seems linked to final cost. MiG-29 to go as soon as possible but I've not heard of the planned demise of the SU-22 though, but can see the logic of it. The crews seem to have quite a soft-spot for the SU-22, so they may have to wrestle them from them. Not much love remaining for the MiG-29, to say the least.
