| The
            F101 was designed for the B-1 strategic bomber and first flew
            on the prototype in 1974.  When the B-1B was approved, GE
            developed the F101-102...GE's first augmented turbofan.  By the
            time production ended in 1987, 469 F101-102s had been produced.
             Using the same core design, the  F110 and F118
            engines were created by adding different fan and afterburner
            packages.  Another derivative of the F101 is the CFM56.  |
