QH-50D

The QH-50 DASH (Drone Anti-Submarine Helicopter) is intended to act as a long range anti-submarine weapon for ships otherwise too small to accomodate a hangar and helicopter. A major component of the FRAM program, the QH-50 was assigned to older ships, such as the Gearing-class destroyers, and also equipped the postwar ocean escorts. The helicopter suffered from a high failure rate as it proved unreliable in shipborne service, and was withdrawn from service by 1973. The JMSDF were the only foreign operator of the QH-50, who had greater success in operations thanks to regular service, later retiring them in 1977. The QH-50D was an improvement over the QH-50C, incorporating a larger 365 shp engine, fiberglass rotor blades, and no tail assembly.
