A-19 (V-11/12)

In the summer of 1935. the first flight of the prototype Vultee V-11 attack bomber took place. The wing and landing gear was the same as the V-1A, but the tail unit was changed; in addition, the new fuselage had an elliptical cross-section and a long tall canopy that covered both cockpits.

Soon the first flight of the prototype V-11G aircraft took place, instead of the Wright Cyclone engine, a new SGR-1820-G2 Cyclone engine with a capacity of 1000 hp was installed on it. Another prototype was proposed - a three-seater V-11GB. The Chinese government ordered 30 V-11G aircraft, the USSR ordered one aircraft as a sample for licensed production with the designation BSh-1. The flight characteristics of the device, equipped with the 920 hp M-62 engine, were not high enough. Soviet-made cars received a new designation PS-43 and were used as mail aircraft.

US Army Air Corps in 1939. acquired seven V-11GB aircraft for evaluation tests, which were designated YA-19. Three vehicles were converted for engine testing under the designations XA-19A (Lycoming O-1230-1), XA-19B (Pratt & Whitney R-2800-1) and XA-19A (Pratt & Whitney R-1830-51 "Twin Wasp ).

In 1939. for the first time a V-12 aircraft took off. It featured improved aerodynamic performance and had a more powerful Pratt & Whitney Twin Wasp engine. The Chinese government has ordered one such aircraft, modified to accommodate the 1,050hp Wright Cyclone 9 engine and redesignated the V-12C. It was armed with two 12.7 mm machine guns and four 7.62 mm machine guns. In addition, it carried a bomb load weighing up to 490 kg.

Then the attention of the Chinese side was drawn to the more powerful V-12D aircraft, which featured a new fuselage design and had a 1600 hp Wright GR-2600-A5B engine. and the armament is the same as on the V-12C variant. Two aircraft were sent to China as samples, and licensed construction of 50 aircraft began. After the CAMCO plant was damaged by Japanese bombing, all the surviving components of the unfinished V-12D aircraft were sent to India, where several aircraft were assembled at the Hindustan Aircraft plant, which were later sent back to China.
