The Soviet Sukhoi Su-2 ( Russian Сухой Су-2 ) was a two-seat bomber aircraft in composite construction and at the time of the German attack on the USSR in 1941 the most modern light bomber of the Soviet air force . It was developed by Pavel Sukhoi .
History and commitment
The development of this type began after a tender by the Council for Labor and Defense on December 27, 1936 in the ZAGI , headed by Andrei Tupolev , as the successor to the R-5 biplane . The first prototype ANT-51 (project name Ivanov ) equipped with an M-62 engine flew for the first time on August 25, 1937 with Mikhail Gromov at the wheel.
After Pawel Sukhoi opened his own design office, a total of three prototypes with different engines were tested. The last one to emerge in 1939 was the BB-1 (BB = Blischni Bombardirowschtschik = close-up bomber) with the M-87A engine , which was converted to the M-88 engine in 1940 and went into series production as the Su-2 . Compared to the prototype designed in all-metal construction, the series version was manufactured in a mixed construction because duralumin was not available in sufficient quantities. At the beginning of 1941 an improved production version followed with the more powerful M-88B engine, which, after the armament had been reduced from four to two MG, could also carry six RS-82 missiles .
From autumn 1941 a Su-2 with the ASch-82 star engine appeared. From it the Su-4 ( BB-3 ) with armored cabin was developed in 1942 . This had a more powerful M-90 engine with 2,095 hp (1,541 kW) and two 12.7 mm and two 7.62 mm machine guns as armament. The guy didn't go into series production.
The production of the Su-2 ran until autumn 1942 and comprised 793 copies. Ultimately, the aircraft was defeated by the Il-2 , which in particular offered significantly better armor and more powerful armament with slightly poorer flight performance.
In combat use as attack aircraft, the Su-2 squadrons suffered heavy losses against the German troops, which is why from 1942 the machines were withdrawn from direct frontline use and used in the hinterland for school and towing tasks. An armored attack aircraft version with an M-88B engine, developed in 1940 and called SchB , did not get beyond the prototype stage. Although the Su-2 was designed as a light bomber, it was mainly used as a reconnaissance aircraft during the war.
