The company «Kaman» in 1980-e, which traditionally occupied a narrow niche of the supplier of anti-submarine helicopters and unable to compete on an equal footing with large aviation manufacturers, tried to gain a foothold in niche, narrow aviation equipment markets. In the last decade of the practical work of Kaman Charles, this was the market of "flying cranes". The construction of a flying crane practically from scratch, and not on an already existing platform would give an opportunity to increase the economy of the machine. The prototype KMAX took off shortly after leaving the position of the manager of Kamana in 1991, the first serial KMAX in January 1994.
