Tupolev DB-1

The Tupolev DB-1 was a Soviet long-range bomber developed in the 1930s. It was developed from the Tupolev ANT-25 distance record-breaking aircraft. Development was prolonged and it was recognized as obsolete by the time it was in production. Only eighteen were built and all were withdrawn from service in 1937.
==Development==
The possibilities of exchanging some of the fuel of the ANT-25 for bombs and/or cameras was recognized early in its development and the VVS issued a requirement for an aircraft to carry over an operational radius of at a speed of . The Tupolev OKB had prepared a design and built a mock-up by August 1933, using the internal designation of ANT-36, and the VVS approved both. Series production of a first batch of 24, out of a planned total of 50, was initiated in the new Factory No. 18 at Voronezh in 1934, but only a total of 18 were built before the program was canceled.〔Gordon, p. 66〕
The airframe, engine and crew compartments were retained from the ANT-25 almost unchanged, although the co-pilot's and navigator's positions were each given one DA machine gun for defense. The DB-1 (long-range bomber model 1), as it was designated in VVS service, was given a smooth skin and a bomb bay was built in the wing center section that carried ten FAB-100 bombs nose-up. An AFA-14 camera was mounted in the rear cockpit, but other cameras could be carried in lieu of the bombs.〔Gunston, p. 86〕
