Design and development

In 1945 the United States Navy funded the development of a turboprop engine. The T34 was produced from 1951 to 1960, but never used in a U.S. Navy aircraft production.[2]

The YT34 engine with 3 wide bladed propellers was made for two Navy R7V-2 (C-121s) variants, for testing. Flight tests were 1 September 1954.[3]

In September 1950, a testbed Boeing B-17 Flying Fortress flew with a T34 turboprop mounted in the nose of the bomber. The first application for the T34 was the Boeing YKC-97J, which later became the Model 377 Super Guppy. The next application for the engine was the Douglas C-133 Cargomaster.[2]
