Kaman HH-43 Huskie

The Kaman HH-43 Huskie was a helicopter with intermeshing rotors used by the United States Air Force, the United States Navy and the United States Marine Corps from the 1950s until the 1970s. It was primarily used for aircraft firefighting and rescue in the close vicinity of air bases, but was later used as a short-range overland search and rescue aircraft during the Vietnam War.

Under the aircraft designation system used by the U.S. Navy pre-1962, Navy and U.S. Marine Corps versions were originally designated as the HTK, HOK or HUK, for their use as training, observation or utility aircraft, respectively.

Operational History

In 1947 Anton Flettner, a German aviation engineer, was brought to New York in the United States as part of Operation Paperclip.[1] He was the developer of Germany’s Flettner Fl 282 “Kolibri” (Hummingbird), a helicopter employing the “synchropter” principle of intermeshing rotors, a unique design principle that dispenses with the need for a tail rotor. Flettner settled in the US and became the chief designer of the Kaman company, where he designed new helicopters using the synchropter principle.
