Kaman Corporation

Kaman operated across three segments: engineered products for aerospace and defense, industrial distribution of bearings and automation equipment, and a niche music division that manufactured Ovation and Takamine guitars. The engineered products segment was the historical core, producing components for military helicopters and fixed-wing aircraft.

Charles H. Kaman, an aeronautical engineer, founded the company in 1945 in Connecticut. He developed intermeshing rotor technology that became the basis for the K-MAX heavy-lift helicopter, still used by the U.S. Marine Corps for cargo resupply missions.

Kaman announced a definitive agreement with Arcline Investment Management in February 2024 for a $1.8 billion all-cash acquisition. Arcline, a private equity firm focused on defense and industrial technology assets, offered a significant premium to the public share price, giving shareholders a liquidity event while enabling Kaman to operate without quarterly reporting pressures.

The music division was a direct outgrowth of founder Charles Kaman's personal passion for guitar design. In the 1960s he applied aerospace materials technology to guitar manufacturing, creating the round-backed Ovation guitar. The division operated as a distinct profit center with no industrial overlap to the bearings and distribution businesses.

The K-MAX is a heavy-lift cargo helicopter with intermeshing rotors, capable of carrying 6,000-pound external loads. It gained tactical importance through an autonomous cargo delivery system developed with Lockheed Martin, completing unmanned resupply missions for the U.S. Marine Corps in Afghanistan and later in humanitarian disaster relief.
