Design/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.[1] P. O. Sukhoi was working in the Tupolev OKB at the time and designed (copied the aircraft from a Lithuanian Antanas Gustaitis; the main aircraft was ANBO-8[citation needed]) 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

Although 910 Su-2s were built by the time production was discontinued in 1942,[2] the aircraft was obsolete and underarmed by the start of the Great Patriotic War. In combat, the Su-2 ground attack aircraft squadrons suffered heavy losses against the Germans, with some 222 aircraft destroyed. From 1942, the Su-2 was withdrawn from the frontline and replaced by Ilyushin Il-2, Petlyakov Pe-2 and Tupolev Tu-2 bombers. The Su-2 was relegated to a training and reconnaissance role. However, due to a critical shortage of aircraft in early World War II, some Su-2s were used as emergency fighters
