In 1942, the Spanish government arranged a manufacturing licence with Messerschmitt AG to build the Bf 109 G-2, although the DB 605A engines, propellers, instruments and weapons were to be supplied from Germany. This proved impossible as Germany was incapable of meeting its own needs, let alone Spain's, and only 25 airframes (without their tails) and less than half the necessary drawings were actually delivered.[1] Consequently, Hispano Aviación replaced the DB 605A engine with the 1,300 hpHS 89-12Z and the project was renamed Bf 109 JbyMesserschmitt.[2] The HS 89-12Z engine performed a successful flight in a Bf 109 E used as a flying testbed in Barcelona in 1944, and the first HA-1109-J1L made its maiden flight on 2 March 1945 in Seville, using a VDM propeller and lash-up engine mounting.[3] The remaining 24 airframes were flown during 1947–9 with Escher-Wyss props, but never became operational.
In May 1951, a developed version, the HA-1112-K1L, improved the Hispano-Suiza, HS 17-12Z engine installation, and carried either one or two 12.7mm Bredamachine guns and Pilatus eight-packs of 80mm rockets. Its three-bladed de Havilland Hydromatic propeller earned it the nickname Tripala ("three blades").[3]
It first flew in 1951, and although 200 were planned only 65 were built. The Hispano engine was an upright V12 instead of the inverted V12 Daimler-Benz DB 601 & 605 engines used in the Bf 109 but, being of compact design, it fitted the airframe of the Bf 109 well and was able to credibly represent the Bf 109 in the German 1957 film Der Stern von Afrika (The Star of Africa) about Luftwaffe ace Hans-Joachim Marseille. The original design, starting with the Bf 109F, had an asymmetrical tail-fin aerofoil with a left deflection to counteract the torque from the Daimler-Benz's clockwise rotation. Because this was left unchanged in the Tripala despite the Hispano V12 having a counter-clockwise rotation, the tail and the engine together induced a right swing on takeoff that was hard to counteract.
A second version, the HA-1110-K1L, was a two-place tandem trainer model.[3]

The final variant was the HA-1112-M1L Buchón (Pouter), which is a male dove in Spanish. It first flew on 29 March 1954 with a 1,600 hpRolls-Royce Merlin 500-45[4] engine and Rotol four bladed propeller, both purchased as surplus from the UK.[4] This engine had a chin intake that altered the lines of the Bf 109's airframe. It was an improvised assembly of outdated components but this was appropriate for the intended purpose of controlling Spanish colonial territories in Africa, where more sophisticated technology was both unnecessary and unavailable in isolated Spain at the time. It carried two 20 mm Hispano-Suiza 404/408 cannons and two OerlikonorPilatus eight-packs of 80 mm rockets and remained in service until 27 December 1965.

HA-1109-J1L
1945 – the initial 25 units built of the Bf 109 G-2 aircraft, from German production, with Hispano-Suiza 12Z-89 engines fitted, in lieu of Daimler-Benz DB 605A's, using VDMorEscher-Wyss propellers. Not used operationally.
