Mule

H-25A Army Mule light cargo helicopter (1953). The Piasekci H-25 was an eight-place tandem rotor helicopter developed for the U.S. Navy for naval rescue operations. With minor modification, it met Army needs for a light cargo and utility helicopter. The maximum Army inventory reached 63 in 1955. All inventory aircraft were later turned over to the U.S. Navy. The H-25 had two three-bladed counterrotating rotors. The H-25 was powered by a single Continental Motors nine-cylinder radial R-975-46 475 hp engine and had a cruising speed of 92 mph (80 knots).
