  • World's first Short Take Off and Vertical Landing (STOVL) engine
  • Thrust range up-to 23,800 lbf

The Pegasus powers the Harrier aircraft, providing full Short Take Off and Vertical Landing (STOVL) capabilities which eliminates the need for conventional runways.

The latest variant of the Pegasus, the 11-61, provides up to 15 per cent more thrust at high ambient temperatures, plus benefits of reduced maintenance and twice the hot-end life of earlier versions. These changes enhance the combat effectiveness, while cutting the cost of engine ownership.

This latest engine variant also enables a highly effective radar equipped version of the Harrier II. This aircraft, the Harrier II+, combines the proven advantages of day and night STOVL operations with an advanced radar system and beyond-visual-range missiles.

The engine is still in service today with the United States Marine Corps, but is no longer in production. Since its entry into service, more than 1,200 engines were produced accumulating more than 2 million flying hours.
