In 1942, the Spanish government received a licence to build the Messerschmitt Bf 109G-2, with DB605A engines, propellers, instruments, and weapons being supplied by Germany. Germany was incapable of meeting Spain's needs, so Hispano substituted the Hispano-Suiza 12Z-89 engine, which flew at Barcelona in 1944. A developed version, with an improved installation for the Hispano-Suiza 12Z-17 engine, appeared in May 1951 as the HA-1112-K1L.
