CASA 2.111 based on Heinkel He 111
The CASA 2.111 was a medium bomber derived from the Heinkel He 111 and produced in Spain under licence by Construcciones Aeronáuticas SA (CASA). The 2.111 models differed significantly in details from Heinkel's wartime He 111H design while using essentially the same airframe in appearance, featuring heavier armament and eventually Rolls-Royce Merlin engines.Design and development
In 1937, during the Spanish Civil War, the Spanish Nationalist Air Force received a number of He 111Bs from Germany, which had begun to receive the improved He 111D model, receiving He 111Es following the end of the war. There was a need for more modern aircraft, however, so in 1940, CASA negotiated a contract with Heinkel to produce 200 examples of the newer He 111 H-16 in Seville. Setting up production was slow, with relatively little support received from Germany as World War II continued. Spain managed to locate a store of Jumo 211F-2 engines in France, and this allowed completion of 130 Jumo powered examples (although only 117 were delivered owing to the need to cannibalise engines). These were in three versions: the 2.111A, a medium bomber; the 2.111C, a reconnaissance bomber; and the 2.111F, a dual-control trainer.
