The GE Military engine family has "gone green" with its F138 propulsion system for the Lockheed Martin C-5M Super Galaxy aircraft. In addition to providing significant improvements in thrust, noise, emissions and fuel consumption, the F138 helps aircraft utilize more airports than ever before. CF6 aircraft also power a broad range of military and VIP applications.
