Soviet Union's Sukhoi Su-2 close support; BB-1 (Blizhny Bombardirovshick, short ranged bomber)


  • Sukhoi Su-2 fighter bomber
  • Sukhoi Su-2 fighter bomber


Pavel Osipovich Sukhoi designed the Su-2 in 1936.

The production version was initially known as the BB-1, but in 1941 it was changed to the Su-2.

A photo turret could be installed on the starboard side.


The cockpit had a raised sliding canopy for the pilot. Heat was fed through the pilot's seat via a pipeline that ran along the starboard side.

The navigator / gunner was protected by 0.5" / 9 mm of armor.


The wings were all metal. To reduce drag the outer sections of the wings of the Su-2 were flush riveted.

Under the wings there could be 550 lb / 250 kg of bombs mounted.

Bomb bay

The bomb bay could carry up to 882 lb / 600 kg of bombs.


The Su-2's fuselage was constructed of wood with a load bearing skin.

At the rear of the fuselage there was a Duralumin constructed escape hatch. Sometimes a MG would be fitted to provide additional protection from the rear.


The propeller was a variable pitch VlSh-23.


Initially the Su-2 had a M.88 radial engine (950 HP). After the first 100 aircraft were constructed a M.82 (1,400 HP) was installed.


The ANT-51 first flew in August 1937. Tests were unsatisfactory but Sukhoi was authorized to continue to modify the aircraft. To test different engine configurations, three more prototypes were constructed.

The Su-2 first flew in April 1940.


By September 1941 the Su-2s were being produced at the rate of 5 a day.

    • Production: 1940 - Mid 1942


  • Sukhoi ANT-51: Prototype. Had Shvetsov M-62 radial engine (copy of Wright Cyclone).
  • Sukhoi BB-1: Original production model. With a bomb load it flew 230 mph / 370 kph.
  • Sukhoi Su-2: Had Shvetsov M-88B radial engine (1,000 HP).
  • Sukhoi Su-2w/M-82: Fitted with non-retractable skis.
  • Sukhoi Su-6: Had M-82 radial (1,520 / 2,100 HP) engine. Il-2's appearance halted development.


There were fifteen air regiments that were supplied with the Su-2.

After heavy loses the Su-2 was put into second-line units in 1942. The Su-2s were found to not be maneuverable and defensive armament was inadequate.

German Invasion

At the time of the German invasion of the Soviet Union in June 1941, there were about 100 Su-2s available.

Used as a Fighter

During the early months of the Great Patriotic War, Su-2s were sometimes put into use as fighters.


The only ramming attack by a female pilot was done in September 1941 by Yekaterina Zelenko.
