For at least one (and generally more) of the aircraft in the list associated with a given engine, the decision to use the engine was made when the engine was in the final stages of develop- ment. (In the case of the J -57, J-79, andJ-75 this is true of nearly all the aircraft listed. ) No Jist extends beyond 1956. Summary For an engine developed independently of an airframe the de- veloper may constrain the performance, weight, and size of an engine at the start.
