|Engines||4*1350hp Mikulin AM-35A|
The only four-engined bomber the USSR used during WWII.
The TB-7 was developed from the ANT-42 prototypes, flown in 1936- 1937. Radically differed from prototypes by new powerplants (allowing to eliminate odd fifth engine, driving centralized supercharger in the fuselage).
Production started in 1939 and lasted until October 1940, 79 aircraft came out of assembly line. In service since May 1940, and remained there for almost all the War period. Apart of numerous raids deep into Germany held territory (particularly Berlin), TB-7 got his fame for remarkably long flights. Those included Molotov (then Soviet Foreign minister) flight to Washington from Moscow (17,700km) with landings in Scotland, Iceland and Canada in May-June 1942.
Some with M-30B/ACh-30B diesel engines. This solution proved itself unreliable. After production of the AM-35A engine was ceased, Shvetsov M-82 and M-82FN radials were fitted to approximately 50 production series aircraft.
Despite series of aerodynamic improvements, aircraft never achieved an optimum configuration due to a lack of interest on the part of military authorities. Approximately 30 aircraft survived the war and remained in service until the late 1950s.
