and designed for helicopters weighing 4-5 tonnes. It first ran in August 1981 and was introduced commercially in the mid-1980s. It was the first Turbomeca engine to use a single stage turbine, making it more compact than its predecessors. In its original design, the engine was rated at 750 continuous horsepower, though it was designed to allow for future power increases, and the later 2B2 variant made 1,100 horsepower.
