Kaman Corporation /kəˈmɑːn/ is an American aerospace company, with headquarters in Bloomfield, Connecticut. It was founded in 1945 by Charles Kaman. During the first ten years the company operated exclusively as a designer and manufacturer of several helicopters that set world records and achieved many aviation firsts.

In 1956, Kaman began to diversify^[2] as an aerospace subcontractor of McDonnell Douglas, Grumman and others. In the mid-1960s Kaman diversified outside of the aerospace industry, using the expertise Kaman had gained in composite materials and the end of the need for skilled woodworkers to craft wooden rotor blades. Charles Kaman, a guitarist as well as an aerospace pioneer, worked with his engineers and other musicians to create the round-backed, composite-body Ovation guitar, which led to the eventual creation of Kaman Music (now KMCMusicorp). Kaman Music was an independent distributor of musical instruments and accessories, and a major producer of guitars and guitar parts and accessories.
