The Hispano Aviación HA-1112 is a Spanish single-seat propeller-driven fighter. It is a copy of the German Messerschmitt Bf 109G-2, and unofficially known as Me 109J.


By 1942 the Bf 109Ds of the Spanish Air Force were aging, so Hispano Aviación obtained the license to build newer Bf 109G-2s. Germany delivered 25 aircraft, but without engines, as it needed them for its own use. Hispano fitted these aircraft with Hispano-Suiza 12Z-89 engines and designated them HA-1109-J1L. The type first flew on 2 March 1945.

The aircraft were later refitted with a better Hispano-Suiza 12Z-17 engine, two 12.7 mm Breda-SAFAT machine guns and a provision for two rocket racks, and were redesignated HA-1112-K1L, appearing in May 1951. 65 were built, although 200 had been planned. It was nicknamed Tripala (Three blades) due to the three-bladed propeller.

The main version, the HA-1112-M1L Buchón (Pouter) made its first flight on 29 March 1954. It was equipped (ironically for a Bf 109 development) with a British Rolls-Royce Merlin 500-45 engine and a four-bladed propeller. The new engine required reshaping the engine cowlings and adding an air intake under the nose. 172 were built.


The introduction of jet fighters had made the HA-1112 obsolescent already during its development, but it was considered to be still adequate for service in colonial territories such as Spanish Sahara. Due to the Spanish Air Force's tight budget, the HA-1112s were kept in service until the end of 1965, and then stored.

Although the nose of the HA-1112-M1L differs significantly from the Bf 109, it has been used in many movies to represent Bf 109s, most importantly in Battle of Britain (1969), where 27 Buchóns were used. Since "Bf 109s" were essential for the movie and genuine Bf 109s couldn't be used, the Spanish Air Force exploited the opportunity and agreed to only sell the Buchóns to the filmmakers for a high price, instead of just leasing them. The filmmakers had no choice but to accept the deal. Many of the Buchóns later became civilian warbirds. Other movies featuring Buchóns disguised as Bf 109s include The Hindenburg (1975), Memphis Belle (1990) and Dunkirk (2017).
