General Note
A J-57 engine, shown here during testing, is capable of developing more than 10,000 pounds of thrust. More than 4,000 of the axial-flow jet engines have been built and now power several of the nation's first line fighter planes including the Air Force's F-100 and F-101, the F-102A and the Navy's F-4D and F8U shipboard fighters. The J-57 has powered more aircraft faster than the speed of sound in level flight than all the other jet engines in the Western world. Eight J-57s power the huge global bomber, the B-52. In the commercial field the J-57, along with Pratt & Whitney Aircraft J-75 will power the giant passenger jet transports now being built by Boeing and Douglas.
