These tubes were difficult to manufacture and required rigorous attention to detail to avoid failure of the fuse. Raytheon was also a contractor for the mass-production of the newly-invented miniature shock-resistant vacuum tubes used in proximity fuses. In 1947, the company demonstrated the Radarange microwave oven for commercial use. In 1945, Raytheon's Percy Spencer invented the microwave oven by discovering that the magnetron could rapidly heat food. Raytheon's research on the magnetron tube revealed the potential of microwaves to cook food. Raytheon ranked 71st among United States corporations in the value of World War II military production contracts. During the war Raytheon also pioneered the production of shipboard radar systems, particularly for submarine detection. At war's end in 1945 the company was responsible for about 80 percent of all magnetrons manufactured. Within a few months of being awarded the contract, Raytheon had already begun to mass manufacture magnetron tubes for use in radar sets and then complete radar systems. ![]() American companies were then sought by the US government to perfect and mass-produce the magnetron for ground-based, airborne, and shipborne radar systems, and, with support from the Massachusetts Institute of Technology's Radiation Laboratory (recently formed to investigate microwave radar), Raytheon received a contract to build the devices. During World War II Įarly in World War II, physicists in the United Kingdom invented the magnetron, a specialized microwave-generating electron tube that markedly improved the capability of radar to detect enemy aircraft. In 1933 it diversified by acquiring Acme-Delta Company, a producer of transformers, power equipment, and electronic auto parts. By the 1930s, it had already grown to become one of the world's largest vacuum tube manufacturing companies. Company, an American manufacturer of electron tubes and switches, to form the successor of the same name, Raytheon Manufacturing Company. In 1925, the company changed its name to Raytheon Manufacturing Company and began marketing its rectifier, under the Raytheon brand name, with commercial success. This made it possible to convert household alternating current to a regulated, high voltage direct current for radios and thus eliminate the need for expensive, short-lived batteries. The electron tube was christened with the name Raytheon (a compound of Old French and Greek meaning 'light from the gods') and was used in a battery eliminator, a type of radio-receiver power supply that plugged into the power grid in place of large batteries. The company's first product was a gaseous ( helium) voltage-regulator tube that was based on Charles Smith's earlier astronomical research of the star Zeta Puppis. Its focus, which was originally on new refrigeration technology, soon shifted to electronics. Smith, founded the American Appliance Company in Cambridge, Massachusetts. Marshall and Vannevar Bush, along with scientist Charles G. In 1922, two former Tufts University School of Engineering, roommates Laurence K. Navy flight test at NAWS China Lake, California (November 10, 2002) Early years History An early Raytheon tube box A Raytheon Tomahawk Block IV cruise missile during a U.S. The company had previously been headquartered in Cambridge, Massachusetts, from 1922 to 1928, Newton, Massachusetts, from 1928 to 1941, Waltham from 1941 to 1961 and Lexington from 1961 to 2003. In 2003, Raytheon's headquarters moved from Lexington, Massachusetts, to Waltham, Massachusetts. As of 2015, it was the third largest defense contractor in the United States by defense revenue. More than 90% of Raytheon's revenues were obtained from military contracts and, as of 2012, it was the fifth-largest military contractor in the world. During 2018, the company had around 67,000 employees worldwide and annual revenues of approximately US$25.35 billion. Įstablished in 1922, the company reincorporated in 1928 and adopted its present name in 1959. In April 2020, the company merged with United Technologies Corporation to form Raytheon Technologies. Raytheon was the world's largest producer of guided missiles. It was previously involved in corporate and special-mission aircraft until early 2007. defense contractor and industrial corporation with manufacturing concentrations in weapons and military and commercial electronics. ![]()
