The J79 engine is a turbojet engine developed by General Electric in the 1950s. It was designed for high-speed aircraft and became widely used in military jets, including the McDonnell Douglas F-4 Phantom II and the North American F-100 Super Sabre. The engine is known for its reliability and performance, providing thrust of up to 17,000 pounds. This engine features an axial-flow design, which allows for efficient airflow and high-speed operation. The J79 was one of the first engines to incorporate afterburner technology, enhancing its thrust during takeoff and combat situations. Its impact on aviation technology has been significant, influencing future jet engine designs.
