T55 Turboshaft Engine

Overview
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 20% more power and uses 8% less fuel than its predecessor. The next-generation T55 is a 6,000-shp class engine 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.
