RATTLRS

The Lockheed Martin RATTLRS (Revolutionary Approach To Time Critical Long Range Strike) is an advanced cruise missile concept demonstration funded by the US Navy with the view to develop technologies that would then be used to develop a successor to the BGM-109 Tomahawk.

Lockheed’s Skunk Works is the prime contractor, while Rolls Royce Liberty Works is designing the YJ102R high-Mach turbine engine. The missile's airframe is similar in size and shape to the engine nacelle of the SR-71.
