The Sukhoi Su-2 (Russian:Сухой Су-2) is a Soviet reconnaissance and light bomber aircraft used in the early stages of World War II. It was the first airplane designed by Pavel Sukhoi. The basic design received an engine and armament upgrade (Su-4) and was modified for the ground-attack role (ShB).
Development
In 1936, Joseph Stalin released a requirement for a multipurpose combat aircraft. Codenamed Ivanov, the airplane had to be capable of performing reconnaissance and then attacking the targets it located. P. O. Sukhoi was working in the Tupolev OKB at the time and designed the "Ivanov" aircraft under the tutelage of Andrei Tupolev. The resulting ANT-51 flew on 25 August 1937 with M. M. Gromov at the controls. Powered by a 610 kW (820 hp) Shvetsov M-62 air cooled radial engine, the ANT-51 reached 403 km/h (220 kn, 250 mph) at 4,700 m (15,420 ft). This was considered insufficient but since the basic design was sound, it was decided to re-test it with a more powerful engine. Equipped with a 746 kW (1,000 hp) Tumansky M-87 engine, the ANT-51 reached 468 km/h (255 kn, 290 mph) at 5,600 m (18,370 ft) and was accepted into production as BB-1 (Blizhniy Bombardirovschik; Russian: Ближний Бомбардировщик — "short-range bomber"). In 1940, the aircraft was renamed Su-2 and the unreliable M-87 engine was replaced with a Tumansky M-88. This lightened version with an M-88B engine reached 512 km/h (275 kn, 320 mph) in testing.
The Su-2 was of mixed construction. The fuselage was semi-monocoque with wood spars and a plywood skin. The wings were of duralumin and steel construction with fabric-covered rod-actuated control surfaces. The pilot and gunner were protected with 9 mm (0.35 in) of armor. The taildragger landing gear was retractable, including the tailwheel.
