In addition to proving their mettle in the harshest military operating environments imaginable, T700/CT7 engines are the power of choice in 50 countries and 130 customers for transport, medical evacuation, air rescue, special operations and marine patrol. A product of continuous innovation, the story of the T700 will continue unfold as it incorporates advanced components and materials for increased power, reliability and fuel savings.
Fighting Extreme Wildfires with Extreme Machines
One weapon in the Los Angeles County Fire Department’s arsenal is the Firehawk, a modified Black Hawk UH-60 helicopter that can carry 1,000 gallons of water and fly near intense fires causing huge temperature swings.
Sikorsky originally developed the chopper for the U.S. Army. But the Firehawk, which is powered by a pair of souped-up T700 GE helicopter engines, has been modified for firefighting, rescue, external lift and medical evacuation.
