Kaman Aerospace /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.


Charles Kaman founded the company in December 1945 with $2,000 of capital and his invention of the servo-flap controlled rotor.[3]

January 15, 1947 
K-125 - Kaman's first helicopter; Kaman selected an intermeshed contrarotating twin rotor design.
July, 1949 
K-225 - An improved version of the K-125; the U.S. Navy bought two and the U.S. Coast Guard one for $25,000 each. Later, they received the H-22 designation.
December 1951 
A modified K-225 equipped with a Boeing 502 (YT50) turboshaft engine becomes the world's first gas turbine powered helicopter.[4] This aircraft is now at the Smithsonian Institution's National Air and Space Museum.
Kaman produced the first electrically powered drone
April 1953 
Ordered for the U.S. Marine Corps, the HOK-1 first flies; Air Force version was the H-43A Huskie
K-16 A V/STOL designed around a rotoprop
March 1954 
A modified Kaman HTK-1 becomes the world's first twin-turbine powered helicopter
September, 1956 
HH-43 Huskie — A variant of the OH-43, equipped with a Lycoming T-53 gas turbine engine
July 1957 
QH-43 - A HTK-1 modified as a UAV[5]

In the late 1950s, Kaman built the Kaman K-17, an experimental tip jet powered helicopter[6] using a Blackburn Aircraft-built Turbomeca Turmo turbine powering a compressor delivering cold air to the rotor tips.[7]

The HU2K-1, selected by the U.S. Navy as a general purpose naval helicopter, makes its first flight on July 2, 1959. It enters service as the UH-2A Seasprite in 1962.

March 1960 
Kaman develops and flies the first all-composite main rotor blade.

In October 1961 the H-43 Huskie set an altitude record of 10,000 m (33,000 ft) and rate of climb records. Anton Flettner who emigrated to the United States and became the chief designer for Kaman Aircraft, creating the Kaman HH-43 Huskie

During the Korean and Vietnam Wars, the Huskie flew more rescue missions than all other aircraft combined, with the best safety record of any U.S. military aircraft.
UH-2A / B production begins
January 1964
First flight of Kaman's experimental Convertiplane equipped with a GE J-85 turbojet engine and wings from a Beechcraft Queen Air. The aircraft achieves speeds of over 320 km/h
Tomahawk — A Seasprite modified with stub wings and a pair of twin guns side-by-side under the nose. Kaman's proposal for the U.S. Army 's interim gunship helicopter between the AAFSS (AH-56) and AAH (AH-64) competitions. Lost to the Bell 209 (AH-1 HueyCobra)

Due to the limited power of its single engine, the Seasprites are modified for the U.S. Navy into twin turbine helicopters.

U.S. Navy begins Light Airborne Multi-Purpose System (LAMPS) development to obtain an onboard helicopter for escort ships
SAVER — The Stowable Aircrew Vehicle Escape Rotoseat is the first jet-powered autogyro with telescoping rotor blades
May 1973 
SH-2F Seasprite — The LAMPS Mk I enters U.S. Navy service
July 1976 
Kaman designs and begins manufacturing the K-747 blade, the world's first production all-composite rotor blade for the Bell AH-1 Cobra helicopter. Total production exceeds 4,000 blades.
January 1991
