Aiding this application was the adoption of the definitive RH-53D variant, which introduced T64-GE-415 engines of greater power and the option to mount a refueling probe and sponson tanks. The mine countermeasures equipment is towed behind the aircraft from a heavy trapeze attached to the rear ramp and rear fuselage.
