Overview
North American Aviation (NAA) was an American aerospace manufacturer founded in 1928 by Clement Melville Keys. It began as a holding company that acquired interests in airlines and aviation businesses, but federal regulation following the Air Mail Act of 1934 forced the separation of airline ownership from aircraft manufacturing. Under president and chief executive James H. “Dutch” Kindelberger, the company became a major producer of aircraft and gradually established itself as one of the most important American defense and space contractors. General Motors acquired a controlling interest in North American in 1933 and combined it with General Aviation Manufacturing Corporation while retaining the North American name. Kindelberger moved the principal manufacturing operation from Dundalk, Maryland, to the Los Angeles area and initially emphasized training aircraft rather than attempting to compete immediately with established manufacturers on large military programs. Early products included the GA-15 observation aircraft, GA-16 trainer, O-47, and BT-9. The BT-9 family led to the T-6 Texan, one of the most widely used military training aircraft ever built. The Second World War transformed the company. North American expanded production into Columbus, Dallas, and Kansas City and became a major supplier to the United States and its allies. Its B-25 Mitchell medium bomber served in every major theater and became associated with the 1942 Doolittle Raid. The P-51 Mustang, initially developed for Britain, became one of the best-known Allied fighters after adoption of the Rolls-Royce Merlin engine. North American also produced the A-36 ground-attack derivative and built approximately 17,000 T-6 trainers. Wartime expansion brought labor conflict, including a 1941 strike at the Inglewood plant that was ended after federal intervention. After the war, demand collapsed sharply and employment fell from a wartime peak of roughly 91,000 to about 5,000 in 1946. North American nevertheless continued to develop new military aircraft, including the F-82 Twin Mustang, B-45 Tornado, FJ Fury, AJ Savage, T-28 Trojan, F-86 Sabre, F-100 Super Sabre, A-5 Vigilante, OV-10 Bronco, T-2 Buckeye, and T-39 Sabreliner. The F-86 became especially prominent during the Korean War, while the T-2 served generations of United States naval aviators. Cancellations of the Navaho missile and the F-107 and F-108 aircraft programs weakened the company in the late 1950s. NAA also diversified into nuclear technology, missile guidance, propulsion, and spaceflight. Its Atomics International division developed experimental and power reactors, while Autonetics produced navigation, guidance, radar, and data systems, including technology associated with the Minuteman missile. Rocketdyne, established as a separate division in 1955, supplied engines for several American launch vehicles and missile programs. Under chief executive Lee Atwood, North American increasingly concentrated on space work. It built the airframe of the X-15 rocket plane, produced Little Joe launch vehicles for Project Mercury, became prime contractor for the Apollo command and service module, and built the S-II second stage of the Saturn V. The Apollo 1 cabin fire in January 1967 created intense public and congressional scrutiny, although later congressional review did not assign sole responsibility to the company. In September 1967, North American merged with Rockwell-Standard to form North American Rockwell. The combined company continued producing Apollo spacecraft and later won the Space Shuttle orbiter contract in 1972. It adopted the Rockwell International name in 1973. The North American Aviation corporate identity ultimately disappeared through successive corporate reorganizations. Rockwell International sold its defense and space operations, including Autonetics and Rocketdyne, to Boeing in 1996. Boeing initially used the North American name for the acquired activities before integrating them in…
History
North American Aviation was founded on December 6, 1928, by Clement Melville Keys as a holding company for airline and aviation investments. The Air Mail Act of 1934 compelled the breakup of such holding structures, pushing North American toward aircraft manufacturing. General Motors had acquired control in 1933 and combined the company with General Aviation Manufacturing Corporation. James H. Kindelberger, recruited from Douglas Aircraft, moved the main operation from Dundalk, Maryland, to Los Angeles and adopted a strategy centered initially on training and observation aircraft. The company’s early designs included the GA-15, GA-16, O-47, and BT-9. The BT-9 lineage produced the T-6 Texan, which became a standard trainer for the United States and allied air forces. North American expanded substantially during the Second World War, opening or enlarging facilities in California, Ohio, Texas, and Kansas. The B-25 Mitchell served across the war’s major theaters, while the P-51 Mustang evolved from an aircraft ordered for Britain into a highly effective long-range fighter after receiving the Rolls-Royce Merlin engine. The A-36 provided a ground-attack derivative, and the company’s wartime production placed it among the leading American industrial contractors. Expansion also produced labor tension. In 1941, a wage dispute at the Inglewood plant developed into a wildcat strike that halted a significant portion of fighter production. Federal authorities intervened, and the workforce returned under pressure from the government and union leadership. After V-J Day, military orders collapsed and employment fell from approximately 91,000 to approximately 5,000 by 1946. North American survived the contraction through continued research and new aircraft programs. It developed the F-82 Twin Mustang, B-45 Tornado, FJ Fury, AJ Savage, T-28 Trojan, and later the F-86 Sabre and F-100 Super Sabre. The F-86 became one of the defining Western jet fighters of the Korean War. North American’s Columbus division broadened its portfolio with the A-5 Vigilante, OV-10 Bronco, T-2 Buckeye, and T-39 Sabreliner. The company also entered specialized technology fields. Atomics International, created from a nuclear research department in 1948 and formally named in 1955, worked on experimental and power reactors, including the Sodium Reactor Experiment and SNAP-10A space nuclear system. Autonetics, originating in a technical research laboratory and becoming a separate division in 1955, developed navigation, guidance, radar, and data systems. Rocketdyne, also separated in 1955, became a major supplier of rocket engines for American missiles and launch vehicles. The company’s later history was increasingly tied to spaceflight. It built the X-15 airframe, Little Joe test boosters, Apollo spacecraft, and the S-II second stage of Saturn V. The Apollo 1 fire in January 1967 exposed serious spacecraft design and test-process problems and generated intense criticism. A congressional review later rejected the idea that North American alone was responsible. In September 1967, North American merged with Rockwell-Standard and became North American Rockwell, later changing its name to Rockwell International in 1973. The successor continued building Apollo spacecraft and won the Space Shuttle orbiter contract in 1972. Boeing acquired Rockwell International’s defense and space operations in December 1996. The acquired units were initially organized under Boeing North American and later integrated into Boeing’s defense activities. Rocketdyne subsequently passed through additional ownership changes, but the principal North American Aviation aerospace legacy is now distributed among Boeing and other successor organizations.
