 At the peak of the Falklands war, however, the Argentine Air Force, in collaboration with the Navy, outfitted an FMA IA 58 Pucará prototype, AX-04, with pylons to mount Mark 13 torpedoes.The aim was the possible production of Pucaras as torpedo-carrying aircraft to enhance the anti-ship capabilities of the Argentine air forces.Several trials were performed off Puerto Madryn, but the war was over before the technicians could evaluate the feasibility of the project.
