So there is zero interoperability among pilots and crews. One pilot/technician has to get massive training on fighter-trainer versions of an aircraft before getting operational on another machine. It's a waste of time/energy/resources to have so many different platforms with different training programs for them. If IRIAF gets its advanced training squadron of 12 x Yasin AT with the same avionics package of Kowsar with IEI e warfare package, Bayenat-II radars with HMD slaved Fatter missiles etc. Pilots who train on them can go to ... Kowsar-I, F-4E/D (dowran upgraded at Busher), Kowsar-II in future, whichever aircraft gets IEI SAIRAN upgrade (MIG?). This happens because they have operated and trained themselves on same-origin electronics, and systems. It IMPROVES combat efficiency multifold without
My assumption is that Yasin is another one of those "Saeqeh" like projects or its variant will get operational but maybe only some 1 training squadron at best.
