Hughes Aircraft was first set up as a subsidiary of Hughes Tool Company, then known as Toolco. In 1935 Hughes built the H-1 Racer , which included every streamlining concept then known, including retractable landing gear, a fully enclosed cockpit, and the first use of recessed rivets. The H-1 captured a number of speed records during the next few years, and made Hughes a household name.

In 1936 Hughes Aircraft was formed as a separate company. During World War II the company designed and built several prototype aircraft including the famous Hughes H-4 Hercules, better known to the world as the Spruce GooseThe Spruce Goose is a nickname commonly given to the Hughes H-4 Hercules an aircraft designed and built by the Hughes Aircraft company. It is the largest flying boat, and has the largest wingspan of any aircraft ever built. Due to wartime restrictions on. However the plant was used primarily as a branch plant for the construction of other company's designs. At the start of the war Hughes Aircraft had only four full-time employees — by the end the number was 80,000.

After the war, Hughes ran afoul of the US Senate. By the summer of 1947, certain politicians had become concerned about Hughes' mismanagement of the Spruce Goose and the XF-11 photoreconnaissance plane project. They formed a special committee to investigate Hughes, but when he successfully tested both planes and then turned them over to the military, they no longer had a target to attack. Despite a highly critical committee report, Hughes was cleared.

• According to an old-timer at Hughes, when the Spruce GooseThe Spruce Goose is a nickname commonly given to the Hughes H-4 Hercules an aircraft designed and built by the Hughes Aircraft company. It is the largest flying boat, and has the largest wingspan of any aircraft ever built. Due to wartime restrictions on flying boatA flying boat is a aircraft that is designed to take off and land on water, in particular a type of seaplane which uses its fuselage as a floating hull (instead of pontoons mounted below the fuselage). Flying boats aircraft were among the largest aircraft was flight-tested, it was filled with beach balls instead of the traditional ping-pong balls used when testing most sea planeDeHavilland Single Otter floatplane in Harbour Air livery A seaplane is an aircraft designed to take off and land on water. Types of Seaplanes There are two types of seaplane the float plane and the flying boat. A float plane has slender pontoons mounteds. Every available beach ball in Los Angeles was purchased for the flight test. After the flight test, the beach balls were handed out to the spectators. In retrospect, this probably shows that Hughes did not intend to fly the aircraft again.

In 1948 Hughes created a new division of the company, Aerospace Group, hiring two engineers, Simon Ramo and Dean Wooldridge , who had new ideas on the packaging of electronics to make complete fire control systems. Their MA-1 system combined signals from the aircraft's RADAR with an analog computerAn analog computer ( American English) or analogue computer ( British English) is a form of computer using electronic or mechanical phenomena to model the problem being solved by using one kind of physical quantity to represent another. The term is used i to automatically guide the interceptor aircraftAn interceptor aircraft (or simply interceptor is a type of fighter aircraft designed specifically to intercept and destroy enemy aircraft, particularly bombers. A number of such aircraft were built in the period starting just prior to World War II and en into the proper position for firing missiles. At the same time other teams were working with the newly-formed US Air Force on air-to-air missiles, delivering the AIM-4 FalconThe Hughes AIM-4 Falcon was the first operational guided air-to-air missile of the United States Air Force. Development Development of a guided air-to-air missile began in 1946. Hughes Electronics was awarded a contract for a subsonic missile under the pr, then known as the F-98. The MA-1/Falcon package, with several upgrades, was the primary interceptor weapon system in the US for many years, lasting into the 1980s.

• Ramo and Wooldridge later joined with Thompson to form TRW, Inc. , another aerospace company. TRW Automotive and TRW Credit are among the successor companies.

As a result of this start, the Aerospace Group was soon massively profitable, and became a primary focus of the company. The company has since built RADAR systems, electro-optical systems, the first working LASER, aircraft computer systems, missile systems, ion-propulsion engines (for space travel), and many other advanced technologies, up to the end of the Cold War.

• Nobel Laureates R.P. Feynman and Murray Gell-Mann had Hughes connections; Feynman would hold weekly seminars at Hughes Research Laboratories; Gell-Mann shared an office with Malcom Currie, later a Chief Executive Officer at Hughes.

Two groups within the Aerospace Group of Hughes Aircraft Company were later spun off in 1977 to form their own Division and ultimately became the Hughes Space and Communications Company. They built the world's first geosynchronous communications satellite, Syncom, in 1963 and followed it closely with the first geosynchronous weather satellite, ATS-1, in 1966. Later that year their Surveyor 1 made the first soft landing on the Moon as part of the leadup to the moon landings in Project Apollo. Hughes also built Pioneer Venus in 1978, which performed the first extensive radar mapping of Venus, and the Galileo probe that flew to Jupiter in the 1990s. The company built nearly 40 percent of the satellites in service worldwide in 2000.

• Two of the astronauts on the last flight of the Space Shuttle Challenger, January 28, 1986 were Hughes alumni: Greg Jarvis and Ronald McNair.

Another division started in 1947 when helicopter manufacturer Kellett sold their latest design to Hughes for production. The H-17 Sky Crane first flew in October 1952, but was commercially unsuccessful. The company formed a new helicopter division in 1955 called Toolco Aircraft Division that began developing light military helicopters. In the May 1965 they won the contract for a new observation helicopter for the US Army, and produced the OH-6 Cayuse - which has remained in production, under various names, to this day. In 1976, Toolco Aircraft Division became Hughes Helicopters, which won the contract for the AH-64 Apache attack helicopter, winning the Collier Trophy 1983. By December 1981 6,000 Apaches had been produced.

• The Tool Company's helicopter test pilots routinely performed 'loop the loop' maneuvers on the flight line in Culver City, with the OH-6A light helicopters[1]. As the helicopter flew upward in the 'loop', the pilot would simultaneously roll it, to re-orient the main rotor upward, at the top of the 'loop'.

When Hughes died in 1976 the empire he built slowly dissolved. In 1984 McDonnell Douglas bought Hughes Helicopters and soon renamed it as McDonnell Douglas Helicopters. In 1985 General Motors bought the rest of the Aircraft division and merged it with their own DELCO Electronics , renaming it Hughes Electronics. In August 1992 General Dynamics sold its Missile Systems business to Hughes. In the fall of 1997, the defense operations of Hughes Electronics merged with Raytheon. Hughes Space and Communications was one of the last of the independent Hughes companies until 2000, when it was purchased by Boeing and became Boeing Satellite Systems. The remaining Hughes companies, DirecTV, DirecTV Latin America, PanAmSat and Hughes Network Systems were purchased by NewsCorp in 2003 and renamed The DirecTV Group. PanAmSat was sold to Kohlberg Kravis Roberts & Co. (KKR)in August 2004.

The amazing range of science and technology spanned by the workers at Hughes Aircraft never included medical applications, because the company was a property of the Howard Hughes Medical Foundation, which exists to this day. This restriction was imposed to avoid even the appearance of a conflict of interest. Ironically, medical applications may well become Hughes' greatest legacy.
