Our T55 family of military turboshaft engines began life, as its designation indicates, in 1955. To date, more than 6,000 T55 engines have been produced, logging some 12 million hours of operation on the Boeing CH-47 Chinook and MH-47 helicopters.

At its introduction, the T55 produced 1,600 shaft horsepower (SHP). Several decades and generations of development later, today’s T55 produces 5,000 SHP and powers the CH-47 Chinook to a maximum speed of 170 knots.

The latest configuration T55-714C delivers 22%  more power and uses 8% less fuel than its predecessor. The next-generation T55 produces 6,000 SHP and is easier to maintain with lower operating costs and increased readiness for the warfighter. It also doubles the operating range for ‘high, hot and heavy’ missions at max payload.
