ANT-51/"Ivanov", A.N.Tupolev, P.O.Sukhoj

Prototype of light bomber/recco, presented by P.O.Sukhoi during a contest-project 'Ivanov' in 1938- 1939. Project started as early as 1935 under general supervision by A.N.Tupolev. Construction started in early 1937 by P.O.Sukhoi brigade at KOZOK, and first aircraft (M-62 engine) was ready without delays.

It was a low-wing single engine bomber-reconnaissater with retractable landing gear. Mixed design (wooden monocoque fuselage, all-metal wing, metal tail surfaces with fabric cover of rudder and elevator) was very rational.

First flight was performed by M.M.Gromov on August 25, 1937. Despite its speed was considered insufficient, but it was superior to all contemporary domestic reconnaissaters. It was decided to launch production and at the same time to continue trials with more powerful engines.

According to Red Army strategic plans, future war with Germany (planned it was!) should be performed on the enemy territory on little expense. The ANT-51 obviously was an aircraft created to support advancing army, under conditions of complete air superiority of the Red Airforce. Ironically, this role was played by its less advanced counterpart Junkers Ju-87 'Stuka'...

Built in series (with increased bomb load) as Su-2/BB-1 light bomber.
