Poland after WW2 never has a big enough aircraft industry to build their own military fighters or bombers aircraft's but rather was an license builder for aircraft's and helicopters which Soviet Union consider esential but not the high-tech at the times and need them manufature somwhere but not delay manufacturing of more esential aircraft's. Except this license production in Poland were designed some jet trainers like in Czechoslovakia. We lost competition for Jet Trainer for whole Warsaw Pact which became Aero L-29 Delfin but Poland became only country in bloc which have their own trainer TS-11 Iskra.
There is also icon of of ill fated I-22 Iryda which were own equivalent of AlphaJet. And TS-16 Grot which was an supersonic trainer. Program closed by soviet commrades because propably only a trainer with some stirke cability but to close to manufacturing serious fighter-bombers.
