Kaman HOK-1



Following evaluation of the Kaman K-225, the US Navy chose the HOK-1 design as best of several submitted in competition for a liaison helicopter. Using the same rotor systems as the K-225, the HOK-1 was put into production off the drawing-board and delivered in quantity to the U.S. Navy and Marines during 1950s. It normally carries four people; but as an ambulance will accommodate two stretcher patients and one sitting patient or medical orderly, in addition to the pilot. Stretcher loading is through the nose, as on the HTK-1.
In service with the U.S. Navy in 1955 as a 4-seat liaison and casualty evacuation helicopter.




As part of a general development programme, several piston-engined helicopters, such as this Kaman HOK-1, were re-engined with gas turbines.
