Developing a Fighter Engine Derivative of the B-1/F101 Engine

The derivation of a fighter engine from the B-1/F101 bomber engine provides an example of the derivative engine development approach, which can provide rapid response to government needs at relatively low cost and with low risk. High contractor motivation, a proven gas turbine core, and available core hardware make the program possible. Significant amounts of both ground and flight testing provide a firm base for a potential decision to continue the development program and establish a demonstrated capability which can easily be transitioned to a production design in that continued effort.
