Development

In August 1962, Kaman Aircraft first flew a prototype civil transport helicopter. It used components of the earlier Kaman K-600 (H-43) with a new fuselage for 12 passengers. Instead of the twin booms of the earlier Huskie, it had a single boom and a ramp-equipped rear door. Sometimes called the Huskie III, the helicopter was powered by two Boeing YT60 turboshafts which were later replaced with two Pratt & Whitney PT6B-11 engines.

The company tried to interest the United States Air Force in the type and it was evaluated for two years, but with no interest in the type, only the prototype was built.
