which first flew in 1930 and was designated E-30 H, was powered by an upright V-8 180 hp (134 kW) Hispano-Suiza 8Ab engine. It had a maximum speed of 180 km/h (112 mph) and a takeoff weight of 1,150 kg (522 lb). A second prototype flew the following year, powered by a 220 hp (164 kW) Hispano-Wright 9Qa, an early licence-built version of the 9-cylinder radial Wright Whirlwind. The third prototype had a modified wing fitted with flaps and Handley Page slots for low speed flight. Production aircraft used a slightly developed version of this radial, the 250 hp (186 kW) Hispano-Wright 9 Qd. The E-30 could be armed, according to its training rôle. Possibilities included a fixed, forward firing 7.7 mm (0.303 in) Vickers machine gun or a similar gun in the rear cockpit. Up to six 12 kg (23 lb) bombs could be attached to under fuselage and fuselage side racks. Operational history The Aeronáutica Militar purchased ten E-30s in 1932-3 and another five in 1935. The Aeronáutica Naval ordered seven between 1933-4, though they were later reported as having eight. The Aeronáutica Militar aircraft had their radial engines cowled with Townend rings and driving a metal propeller; their wings carried Hadley Page slots. the Naval machines had uncowled engines, wooden propellers and folding wings. E-30s were involved in the Spanish Civil War, all but one initially were part of the Spanish Republican Air Force. At first the Republican aircraft were used for bombing and reconnaissance but reverted to the training rôle as more suitable front line aircraft became available. As the war ended, thirteen were captured by the Nationalists, serving briefly with the Aviación Nacional and then, in 1939, with the newly formed Ejercito del Aire until 1945. One remained with the Acedemia de Aviación at León in 1950. Since 1945 Spanish military air force aircraft have had designations describing their rôle. Under this system the E-30 became first the EE.2, as a basic trainer then the E.2 trainer.
