Kaman K-1125

It is no surprise that Kaman Aircraft Corporation's ingenuity resulted in a number of special helicopter projects. Recognizing the potential growth of the H-43B program, Kaman developed the K-1125 helicopter as a private venture. With the improved variant, dubbed the "Huskie III," Kaman had hoped to meet growing national defense needs with a reliable, all-weather, medium-weight aircraft. It was also billed as an ideal helicopter for anti-guerilla warfare, missile site support and down-range recovery work on missile ranges.

The K-1125 was basically an enlarged version of the H-43B, which combined all its dynamic components with a number of improvements. As the nation's first twin-turbine heli-copter in the medium-weight range, the Huskie III was un-veiled on 4 October 1962 at Kaman's Bloomfield plant.

The prototype was powered by two Boeing YT-60 en-gines, each of which developed 500 horsepower. Kaman listed its top speed at 220km/h, with a cruise speed of 195km/h. It had an empty weight of 2370kg and a gross weight of 4760kg. With 300 gallons of fuel, the Huskie Ill's range was 630km, which could be extended to 1320km with the addition of two 150-gallon fuel bladders. A single-boom empennage supplanted the twin boom arrangement, and a large ramp-type rear door, which incorporated stairs, replaced the clamshell doors. Other improvements over its predecessor included a larger cabin, seating 12 troops or 6 VIPs, cabin windows, fiberglass rotor blades, a 1360kg capacity cargo hook, and a chin pod housing electronic gear. Armament was available for the Huskie III in the form of ma-chine guns and rocket pods.

The Huskie III underwent evaluations for two years, but never gained acceptance by the Air Force.
