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 U.S. Navy aircraft production.[3]
The YT34 engine with three wide-bladed propellers was made for two Navy Lockheed R7V-2 Constellation (C-121s) variants, for testing. Flight tests were on 1 September 1954.[4]
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 YC-97J Stratofreighter, which later became the Aero Spacelines Super Guppy. The next application for the engine was the Douglas C-133 Cargomaster.[3]
