In 1925, the company changed its name to Raytheon Manufacturing Company and began marketing its rectifier, under the Raytheon brand name, with commercial success. In 1928 Raytheon merged with Q.R.S. Company, an American manufacturer of electron tubes and switches, to form the successor of the same name, Raytheon Manufacturing Company. By the 1930s, it had already grown to become one of the world's largest vacuum tube manufacturing companies. In 1933 it diversified by acquiring Acme-Delta Company, a producer of

Radiation Laboratory (recently formed to investigate
microwave radar), Raytheon received a contract to build the devices. Within a few months, Raytheon began to manufacture magnetron tubes for use in radar sets, and then complete radar systems. During the war, Raytheon also pioneered the production of shipboard radar systems, particularly for submarine detection. Raytheon was also a contractor for the mass-production of miniature
shock-resistant vacuum tubes used in
proximity fuses. These tubes were difficult to manufacture and required rigorous attention to detail. At war's end in 1945, the company had built about 80 percent of all magnetrons. Raytheon ranked 71st among U.S. corporations in the value of World War II military production contracts.
In 1945, Raytheon's

Satellite sensors
Raytheon, often in conjunction with Boeing, Lockheed Martin or Northrop Grumman, is also heavily involved in the satellite sensor business. Much of its Space and Airborne Systems division in El Segundo, California, El Segundo, California, CA is devoted to this, a business it inherited from Hughes Electronics, Hughes. Examples of programs include:
* Space Tracking and Surveillance System (STSS), being developed for the Ballistic Missile Defense. Raytheon is building the sensor payload. Additionally, the El Segundo site is the company center of excellence for the development and production of laser products.
* Raytheon company's Navy Multiband Terminal (NMT) is the first advanced, next-generation satellite communications (SATCOM) system to successfully log on to and communicate with the U.S. government's Milstar SATCOM system using low and medium data rate waveforms. The system provides naval commanders and sailors with greater data capacity, as well as improved protection against enemy intercept and jamming.
* Visible Infrared Imaging Radiometer Suite (VIIRS), was developed by Raytheon Space and Airborne Sensors and is currently in operation on the Suomi NPP satellite. Future deliveries of VIIRS will fly onboard JPSS to continue the operational space based climate and weather sensing legacy of the MODIS sensors.
Communications
* The company also makes several software radio and digital communication systems for military applications such as Cooperative Engagement Capability (CEC), is participating in Navy-Marine Corps Intranet (NMCI), ECHELON and the Joint Tactical Terminal (JTT) programs.
* Digital Multimedia Watchdog, a tool used by the FBI to record phone calls and Internet communications.
Radioactive materials detection system
As part of the company's growing homeland security business and strategic focus, Raytheon has teamed with other contractors to develop an Advance Spectroscopic Portal (ASP) to allow border officials to view and identify radioactive materials in vehicles and shipping containers more effectively.
Semiconductors
Raytheon also manufactures semiconductors for the electronics industry in sites in the US and UK. In the late 20th century it produced a wide range of integrated circuits and other components, but as of 2003 its US semiconductor business specializes in gallium arsenide (GaAs) components for radio communications as well as infrared detectors. It is also making efforts to develop gallium nitride (GaN) components for next-generation radars and radios. The UK arm specialized in CMOS on silicon carbide (SiC) development and foundry work but is no longer taking on new orders, having been on the premises for 57 years.
Missile defense systems
In the framework of Ground-Based Midcourse Defense, Raytheon is developing a Ground Based Interceptor (GBI) that includes a booster missile and a Projectile#Explosive charge or kinetic, kinetic Exoatmospheric Kill Vehicle (EKV), along with several key radar components, such as the Sea-Based X-Band Radar (SBX) and the Upgraded Early Warning Radar (UEWR).

Environmental record
Two lawsuits were filed against a Raytheon Company plant in St. Petersburg, Florida, due to concern with health risks, property values, and contamination in April 2008.
Raytheon was given until the end of the month to independently test whether or not the groundwater that originated from its area was contaminated. According to the Florida Department of Environmental Protection (DEP), the groundwater contained carcinogenic contaminants, including trichloroethylene, 1,4-dioxane, and vinyl chloride. The DEP also reported that the clouds contained other toxins, such as lead and toluene.
In 1995, Raytheon acquired Dallas-based E-Systems, including a site in St. Petersburg, Florida, In November 1991, prior to Raytheon's acquisition, contamination had been discovered at the E-Systems site. Soil and groundwater had been contaminated with the volatile organic compounds trichloroethylene and 1,4-Dioxane. In 2005, groundwater monitoring indicated polluted groundwater was moving into areas outside the site. According to DEP documentation, Raytheon has tested wells on its site since 1996 but had not delivered a final report; therefore, it was given a deadline on May 31, 2008, to investigate its groundwater.
Contamination in the area has not affected anyone's drinking water supply or health, yet due to negative local media coverage lawsuits are being filed with claims against Raytheon citing decreases in property values.
In another case, Raytheon was ordered by the United States Environmental Protection Agency, Environmental Protection Agency (EPA) to treat groundwater at the Tucson Plant (acquired during the merger with Hughes) in Arizona since Raytheon used and disposed metals, chlorinated solvents, and other substances at the plant since 1951.
The EPA further required the installation and operation of an oxidation process system to treat the solvents and make the water safe to drink.
On 9 August 2006, The Stream Contact Centre in Derry, Northern Ireland, which had a contract with Raytheon at the time, was Raytheon 9, attacked by protesters. They destroyed the computers, documents, and mainframe of the office, and proceeded to occupy it for eight hours prior to their arrest.
The activists were charged with criminal damage and affray under terrorism laws. The trial of six of the accused began May 19, 2008, in the Laganside Courts in Belfast. Colm Bryce, Gary Donnelly, Kieran Gallagher, Michael Gallagher, Sean Heaton, Jimmy Kelly, Paddy McDaid and Eamonn O'Donnell were acquitted of all charges on 11 June, with Eamonn McCann found guilty of the theft of two computer discs.
By 2013, the company was also awarded the Goal Achievement Award by the EPA for excellence in greenhouse gas management.
