Overview

Raytheon is a major American defense and aerospace technology brand whose roots extend to the American Appliance Company, founded in Cambridge, Massachusetts, in 1922 by Vannevar Bush, Laurence K. Marshall, and Charles G. Smith. The founders initially pursued refrigeration technology, but the company soon concentrated on electronics. Its early breakthrough was a helium-filled voltage-regulator tube marketed under the Raytheon name. The device helped replace the large batteries used in early radios with a household alternating-current power supply, creating the commercial foundation for the business. The company expanded rapidly through vacuum tubes, power equipment, maritime electronics, radar, and military systems. During the Second World War, Raytheon became a critical supplier of magnetrons and radar equipment. Its manufacturing contribution to radar helped establish the company as a leading defense-electronics contractor. Raytheon also produced components for proximity fuzes, including miniature shock-resistant vacuum tubes. In 1945, company scientist Percy Spencer discovered that microwave radiation from a magnetron could heat food, leading to the commercial Radarange microwave oven and, later, a substantial consumer-appliance business. After the war, Raytheon moved increasingly toward guided weapons and military electronics. It began missile production in 1948 and developed systems including Lark, Sparrow, Hawk, Phoenix, and Patriot. The company also worked on computers, navigation systems, marine electronics, semiconductors, educational publishing, aircraft, and household appliances. Its acquisition of Amana Refrigeration made Raytheon a major microwave-oven manufacturer, while its acquisition of Beech Aircraft and later the Hawker business created a sizeable general-aviation and business-aircraft operation. Raytheon sold its aircraft activities in 2007. During the 1990s, Raytheon transformed itself into a diversified defense prime contractor through acquisitions of E-Systems, defense businesses formerly associated with Chrysler and Texas Instruments, and Hughes Aircraft's aerospace and defense operations. The Patriot missile's performance and international visibility during the 1991 Gulf War strengthened Raytheon's position in global air and missile defense. By the 2010s, the company focused primarily on missiles, integrated air and missile defense, radar, command-and-control systems, electronic warfare, intelligence, surveillance, reconnaissance, cybersecurity, and other military technologies. More than 90 percent of its revenue was military-related in the period described by the historical record. Raytheon merged with United Technologies Corporation in April 2020 to create Raytheon Technologies, with the combined corporation headquartered in Arlington, Virginia. In 2023, Raytheon Technologies adopted the name RTX Corporation. RTX combined the former Raytheon Intelligence & Space and Raytheon Missiles & Defense activities into a new Raytheon business segment, alongside the Collins Aerospace and Pratt & Whitney businesses. Raytheon therefore remains an active and internationally important operating brand, but it is no longer a separately listed corporation. Its best-known offerings include Patriot air and missile defense, Tomahawk cruise missiles, advanced radar, naval combat systems, and other defense electronics.

History

Raytheon began in 1922 as the American Appliance Company, established in Cambridge, Massachusetts, by Vannevar Bush, Laurence K. Marshall, and Charles G. Smith. The founders soon abandoned their initial refrigeration emphasis and pursued electronics. Their first important product was a helium voltage-regulator tube based on Smith's astronomical research. Marketed as the Raytheon tube, it enabled radio users to draw regulated power from household electricity instead of relying on expensive batteries. The company adopted the Raytheon Manufacturing Company name in 1925 and expanded through a 1928 merger with Q.R.S. Company. Acquisitions such as Acme-Delta broadened its capabilities in transformers, power equipment, and electronic components. World War II established Raytheon as a major defense manufacturer. Working with the U.S. government and the Massachusetts Institute of Technology's Radiation Laboratory, the company mass-produced magnetrons for airborne, shipborne, and ground radar. It also manufactured radar systems and components for proximity fuzes. By the end of the war, Raytheon had produced a very large share of U.S. magnetrons. Percy Spencer's work with magnetrons led to the microwave oven, which Raytheon demonstrated commercially as the Radarange in 1947. The postwar company diversified into marine electronics, radio and television equipment, semiconductors, computers, and guided weapons. It acquired the Submarine Signal Company and developed missile guidance technologies. Raytheon's Lark, Sparrow, Hawk, Patriot, and Phoenix programs helped make missiles and air defense central to its identity. The company also produced the RAYDAC computer for the U.S. Navy and manufactured the Apollo Guidance Computer. Consumer activities grew after the acquisition of Amana Refrigeration, and Raytheon later owned other appliance businesses, including the Speed Queen line for a period. From the 1980s through the 1990s, Raytheon became a broad aerospace and defense prime contractor. Its purchase of Beech Aircraft and the later addition of Hawker business jets created an aircraft division that included King Air turboprops, business jets, trainers, and special-mission aircraft. That operation was sold in 2007. In defense, acquisitions of E-Systems, former Chrysler defense assets, Texas Instruments' defense electronics unit, and Hughes Aircraft's aerospace and defense business added major capabilities in sensors, missiles, command systems, and electronic warfare. Raytheon's Patriot system gained worldwide attention during the 1991 Gulf War. In the 2000s and 2010s, Raytheon concentrated further on defense technology. It acquired robotics, signal-processing, cybersecurity, and intelligence businesses, including Sarcos, Applied Signal Technology, Websense, Foreground Security, and Stonesoft-related assets. The company continued competing for large U.S. military programs, including the Three-Dimensional Expeditionary Long-Range Radar program, later known as 3DELRR. Its business increasingly centered on integrated air and missile defense, precision weapons, radar, electronic warfare, cyber operations, and mission systems. Raytheon merged with United Technologies in 2020. The resulting company was initially named Raytheon Technologies and was headquartered in Arlington, Virginia. In 2023, it was renamed RTX Corporation, and RTX reorganized the former Raytheon Intelligence & Space and Raytheon Missiles & Defense units into the present Raytheon business segment. The Raytheon name consequently continues as a major operating brand rather than an independent publicly traded company. The business remains associated with Patriot, Tomahawk, Standard Missile, AMRAAM, advanced radar, and other systems supplied primarily to the United States and allied governments.
