Pavel Osipovich Sukhoi designed the Su-2 in 1936.1,3

The production version was initially known as the BB-1, but in 1941 it was changed to the Su-2.3

A photo turret could be installed on the starboard side.1


The cockpit had a raised sliding canopy for the pilot.1 Heat was fed through the pilot's seat via a pipeline that ran along the starboard side.1

The navigator / gunner was protected by 0.5" / 9 mm of armor.1


The wings were all metal.1 To reduce drag the outer sections of the wings of the Su-2 were flush riveted.1

Under the wings there could be 550 lb / 250 kg of bombs mounted.1

Bomb bay

The bomb bay could carry up to 882 lb / 600 kg of bombs.1


The Su-2's fuselage was constructed of wood with a load bearing skin.1

At the rear of the fuselage there was a Duralumin constructed escape hatch.1 Sometimes a MG would be fitted to provide additional protection from the rear.1


The propeller was a variable pitch VlSh-23.1


Initially the Su-2 had a M.88 radial engine (950 HP).3 After the first 100 aircraft were constructed a M.82 (1,400 HP) was installed.3


The ANT-51 first flew in August 1937.2,3 Tests were unsatisfactory but Sukhoi was authorized to continue to modify the aircraft.3 To test different engine configurations, three more prototypes were constructed.3

The Su-2 first flew in April 1940.1


By September 1941 the Su-2s were being produced at the rate of 5 a day.1

  • Sukhoi Su-2w/M-82: Fitted with non-retractable skis.1
  • Sukhoi Su-6: Had 2,100 HP engine.3 Il-2's appearance halted development.3


There were fifteen air regiments that were supplied with the Su-2.1

After heavy loses the Su-2 was put into second-line units in 1942.1,3 The Su-2s were found to not be maneuverable and defensive armament was inadequate.3

Used as a Fighter

During the early months of the Great Patriotic War, Su-2s were sometimes put into use as fighters.1


The only ramming attack by a female pilot was done in September 1941 by Yekaterina Zelenko.1
