The Kaman K-MAX (company designation K-1200) is an American helicopter with intermeshing rotors (synchropter) by Kaman Aircraft. It is optimized for external cargo load operations, and is able to lift a payload of over 6,000 pounds (2,722 kg), which is more than the helicopter’s empty weight. An unmanned aerial vehicle version with optional remote controlled has been developed and evaluated in extended practical service in the war in Afghanistan.
After being out of production for more than a decade, in June 2015 Kaman announced it was restarting production of the K-MAX due to it receiving ten commercial orders. The first flight of a K-MAX from the restarted production took place in May 2017 and the first new-build since 2003 was delivered on July 13, 2017 for firefighting in China.
