The T55-GA-714A engine delivers 4868 hp, enabling the CH-47F helicopter to reach speeds in excess of 175 mph and to transport up to 21,016 lb.

The U.S. Army finalized a $79 million contract to continue purchasing Honeywell T55-GA-714A engines and fielding kits for Chinook helicopters. More than 5300 T55 engines have been delivered since its launch, with more than 7 million h of global operation. Honeywell’s engines are being installed on both legacy CH-47D and new CH-47F helicopters. Deliveries to the Boeing CH-47F production line from this latest order will begin in the first quarter of 2010. The U.S. Army has options for two additional years. The 714A delivers a 17% increase in power, 5% reduction in fuel consumption, and increased maintenance intervals when compared to the previous 712-model engine.
