B-2 Engine

Taken from http://www.airforce-technology.com/projects/b2/

The aircraft is powered by four General Electric F118-GE-100 turbofan engines internally mounted in the body of the wings. The engines have an exhaust temperature control system to minimise thermal signature. The engines, rated at 77kN, provide a high subsonic speed and a maximum gross take-off weight of 336,500lb. In-flight refuelling gear is installed in the top centre line of the aircraft behind the cockpit.
