Honeywell announced that it signed a contract to supply 34 T55-GA-714A engines to the United Kingdom’s Ministry of Defence (MOD) for its new H-47 Extended Range Chinook helicopter fleet. The order and supply of the T55 engines is managed through the office of U.S. Army Foreign Military Sales.

Honeywell’s T55 engine is the world leader in powering heavy lift helicopters. Over 900 CH-47 helicopters powered by T55s are operated today by militaries and civil aviation entities around the world. Honeywell’s latest T55-GA-714A engine configuration produces up to 5,000 shaft horsepower, powering Chinook aircraft up to 170 knots even in the most demanding operating conditions.

“We have a long-standing relationship with the United Kingdom Ministry of Defence and we appreciate the opportunity to continue supporting them on their new H-47 Extended Range Chinook Helicopter with our latest T55-GA-714A engine configuration,” said Dave Marinick, president, Engines and Power Systems, Honeywell Aerospace.

“The latest contract to supply 34 T55 engines is a testament to the U.K MOD’s confidence in our battle-proven engines. To date, our T55 engines have logged some 12 million hours of operation on the Boeing CH-47 and MH-47 Chinook helicopters.”

Honeywell first delivered the T55 engine to the U.S. Army in 1961 at 2,200 shaft horsepower for the CH-47A helicopter. Since then, the engine’s power has more than doubled to 5,000 shaft horsepower with ongoing development designed to increase the potential output further while improving maintainability and reliability, and reducing operating costs.

Honeywell continues to evolve and improve the T55 family of engines with our development work on the T55-GA-714C and HTS7500 engines. The next generation 714C engine boasts 6,000 shaft horsepower while consuming 8% less fuel than the current T55.
