	Summary
	The Williams WR19 is the world’s smallest turbofan power plant. It has been used in the Bell Flying Belt, the Williams Aerial Systems Platform (WASP), and the Kaman Stowable Aircrew Vehicle Escape Rotoseat (SAVER). Developments of this turbofan engine power the Foxjet business aircraft and all U.S. cruise missiles under development in 1980.

	Summary
	Small turbine engines such as WR19 are finding industrial, marine, automotive, and pipeline applications. Earlier Williams turbojets powered unmanned target drones and were used as auxiliary power units for military transport aircraft. The initial high cost of such powers is often offset by their efficiency, low operating costs, and low maintenance requirements.
