The Big Rip Off

TU 4 Bull

Towards the end of WW II, a number of B 29 Superfortresse were interned in the USSR. Russia refused to return them. Three were flown to airfields around Moscow and became the genesis of a modern Soviet Strategic Bomber Arm. Russian aircraft designers had been handed an incredibly valuable gift and reverse engineered the B29 into the Tupolev TU 4. “They therefore viewed the unexpected arrival of three B-29s on their soil as an extraordinary windfall, described as a dar Bozhii, or “gift from God,” by bomber pilot Vasiliy Reshetnikov in his memoirs.”1 Lend Lease by a Different Name.

The VVS was in need of a long range Bomber. The Pe 8 was obsolete and a decision had been made to cancel the Ant 124. When the B 29 fell into Russian hands Tupolev’s Design Bureau came under immediate pressure to come up with a four engine bomber – and quick. They did – the first TU4 flew on May 19,1947. Stalin, ever practical, told Tupolev to clone the Superfortress in as short a time as possible instead of continuing with his own comparable ANT-64/Tu-10.[8] The reverse-engineering effort involved 900 factories and research institutes, which finished the design work during the first year, and 105,000 drawings were made.[9] By the end of the second year, the Soviet industry was to produce 20 copies of the aircraft, ready for state acceptance trials.[10]

The effort involved created, perhaps recreated the Soviet aircraft industry in sophistication of product and production management. By the end of the second year 20 TU4’s were in acceptance trials. In spite of materiel differences (skin, alloys) the Tu 4 weighed close to the same as the B 29. Turrets were redesigned to take the more effective Nudelman NS 23mm cannon and “Additional changes were made as a result of problems encountered during testing, related to engine and propeller failures.”

The aircraft was first displayed during a flyover at the Aviation Day parade on 3 August 1947, It was assumed that they were merely three B-29 bombers that were known to have been diverted to the Soviet Union during World War II. Minutes later a fourth aircraft appeared. Western analysts realized that the Soviets must have reverse-engineered the B-29.[22]

A nuclear bomber that gave NATO fits when it appeared: tactics had to be polished in order to meet the new threat – a Soviet B 29! The aircraft functioned in the following major roles: ELINT, ECM, carrier of parasite fighters and gliders, aerial refueling, reconnaissance among other tasks. China received a small number in the 1950’s. The Tupolev TU 4, the start of a modern Soviet Strategic Bomber Arm, was phased out in the 1950’s. A descendant of the TU 4 remains with the VVS to present day – the four engined TU 95 Bear.

To the boon supplied courtesy of the German aircraft industry must be added the American.
