Kaman Seasprite



Kaman proposed the Model K-20 to fulfill the light utility role for the US Navy in 1957 and won! The Kaman design featured four blades on the main rotor and three blades on the tail rotor with a single General Electric T58-8F turboshaft engine located above the cabin. Kaman built four YHU2K-1 Seasprite prototypes in 1958-59. These were redesignated as YUH-2A in 1962.
