McDonnell Aircraft Corporation

McDonnell Aircraft Corporation was an American aerospace manufacturer established by James Smith McDonnell in St. Louis, Missouri, on July 6, 1939. It became one of the major United States military-aircraft companies of the twentieth century, with a portfolio spanning jet fighters, guided missiles, target drones, experimental aircraft, and crewed spacecraft. The company ceased to exist as an independent corporation when it merged with Douglas Aircraft Company in 1967 to create McDonnell Douglas Corporation. McDonnell's origins followed an earlier unsuccessful attempt by James McDonnell to establish an aircraft business in Milwaukee. His first company, J.S. McDonnell & Associates, was formed in 1928 to develop a small aircraft, but the Great Depression undermined the project and the business collapsed. McDonnell subsequently worked for Glenn L. Martin before leaving in 1938 to establish a new company in St. Louis. The new McDonnell Aircraft Corporation initially operated with a small workforce, but World War II created demand for aircraft components and military technology. Employment grew from approximately 15 people in 1939 to about 5,000 by the end of the war. The company also developed the XP-67 Bat fighter prototype and the LBD-1 Gargoyle guided missile. After the war, McDonnell faced a sharp contraction as government orders ended and military aircraft inventories became surplus. The company reduced its workforce, but the Korean War revived demand for combat aircraft and helped establish McDonnell as a significant supplier to the United States military. Its early jet work began during World War II after the company was invited to compete in a United States Navy contest. The resulting FH-1 Phantom became an important postwar jet fighter and introduced a distinctive configuration in which engines were placed forward beneath the fuselage and exhausted immediately behind the wing. Variants of this design approach influenced the F2H Banshee, F3H Demon, and F-101 Voodoo. McDonnell's most prominent aircraft was the F-4 Phantom II. Development began in the 1950s, with David S. Lewis playing a leading role in aerodynamics and program development. The F-4 entered service in 1960 and became one of the best-known American military aircraft of the Cold War, serving in multiple roles and with several operators. The company also pursued missile systems, including the ADM-20 Quail and Gargoyle, while research into high-speed and hypersonic flight supported its participation in NASA's human-spaceflight programs. The Mercury capsule and Gemini capsule broadened McDonnell's identity beyond military aviation. These spacecraft made the company a major contractor in the early American human-spaceflight program, and the success of Mercury was reflected in a corporate logo showing a capsule circling a globe with the motto “First Free Man in Space.” Nevertheless, McDonnell remained heavily dependent on military procurement and had little civilian business, leaving it exposed to fluctuations in defense spending. McDonnell and Douglas began exploring a combination in 1963. Douglas had substantial civilian-aircraft capabilities but was experiencing cash-flow and development-cost difficulties, while McDonnell offered stronger military-contract income. Douglas formally accepted McDonnell's offer in December 1966, and the companies completed their merger on April 28, 1967. The resulting McDonnell Douglas Corporation was headquartered at McDonnell's St. Louis facilities, with James McDonnell as chairman and chief executive. McDonnell Aircraft therefore ended as a standalone brand and corporate entity, although its facilities, personnel, technologies, and defense programs continued within McDonnell Douglas and, after McDonnell Douglas's 1997 merger with Boeing, within Boeing's defense and space activities.

James Smith McDonnell's first attempt to create an aircraft company began in Milwaukee in 1928 with J.S. McDonnell & Associates. The enterprise sought to build a small aircraft for family use, but the economic collapse that followed the 1929 stock-market crash ended the project. McDonnell then joined Glenn L. Martin, gaining experience that later informed his return to independent aircraft manufacturing. McDonnell left Martin in 1938 and founded McDonnell Aircraft Corporation in St. Louis on July 6, 1939. The company entered a market increasingly shaped by military procurement and wartime mobilization. During World War II, it expanded from a very small operation into a substantial aircraft and components producer. Its workforce reportedly grew from 15 employees at formation to approximately 5,000 by the end of the war. Among its wartime and immediate postwar projects were the XP-67 Bat fighter prototype and the LBD-1 Gargoyle guided missile. The end of World War II created severe pressure. Military orders declined, surplus aircraft reduced demand, and McDonnell was forced to cut employment. The Korean War restored the importance of military-aircraft production and helped the company develop into a major fighter supplier. McDonnell had entered jet development in 1943 after receiving an invitation to bid in a United States Navy competition. Its FH-1 Phantom became a successful postwar jet fighter and established a characteristic engine-and-fuselage arrangement that appeared in later designs such as the F2H Banshee, F3H Demon, and F-101 Voodoo. David S. Lewis joined McDonnell as chief of aerodynamics in 1946 and later became executive vice president in 1958. He was appointed president and chief operating officer in 1962. Lewis was closely associated with the development of the F-4 Phantom II, whose program began in the 1950s and which entered service in 1960. The F-4 became the company's signature military aircraft and a major American combat-aircraft program during the Cold War. McDonnell also developed missiles and unmanned systems. Its portfolio included the Gargoyle guided missile, the ADM-20 Quail decoy missile, and the TD2D/KDD/KDH Katydid target-drone family. The company conducted research into hypersonic flight and related high-speed technologies, contributing to its successful pursuit of NASA work. It built the Mercury capsule and Gemini capsule, and also worked on the ASSET spaceplane. The human-spaceflight business gave McDonnell a high-profile role in the early United States space program, although its overall business remained strongly tied to military procurement. McDonnell's dependence on defense spending was strategically significant. The corporation had very limited civilian business, making it vulnerable to peacetime reductions in government orders. Douglas Aircraft Company, by contrast, possessed important civilian-aircraft activities but was experiencing cash-flow problems and the financial burden of development programs. The companies began discussions about a merger in 1963. Douglas accepted McDonnell's proposal in December 1966, and the merger became effective on April 28, 1967. McDonnell Douglas Corporation inherited McDonnell's St. Louis base and military capabilities. James McDonnell became chairman and chief executive, while David Lewis was associated with the Douglas Aircraft Division before returning to a senior leadership role in the combined company. McDonnell Aircraft no longer existed as an independent corporation, but its programs and industrial base continued within McDonnell Douglas. In 1997, McDonnell Douglas merged with Boeing. Boeing's defense and space activities subsequently retained major operations at the former McDonnell facilities in St. Louis, preserving an institutional connection to the company's aircraft and spacecraft legacy.
