Introduction: Raytheon Company was founded in 1922 in Cambridge, Massachusetts, initially known as the "American Instrument Company", by Laurence K. Marshall, his college classmate Vannevar Bush, and young scientist Charles G. Smith. At the beginning, the company mainly focused on the refrigerator business, but after failure, it turned to producing Raytheon brand electronic tubes and achieved great success. In 1925, the company was officially renamed as "Raytheon Manufacturing Company". Ray comes from French, meaning "a beam of light"; Theon comes from Greek, meaning 'from God'. So Raytheon means' beam of light from God ', and there are translations in Chinese such as' thunder god', 'thunder thunder', 'Raytheon', etc. After more than 80 years of development and innovation, Raytheon has become a leading player in industries such as military technology, government and commercial electronics technology, government aircraft, and special mission aircraft. Since its establishment, Raytheon has become a global leader in developing defense technologies and applying them to commercial markets. In recent years, Raytheon has acquired E-Systems, the defense systems division of Texas Instruments, and Hughes Aircraft Corporation. Through strategic mergers and acquisitions, Raytheon has greatly enhanced its ability to serve customers. Thor focuses its core business on three areas: defense and business electronics, commercial and special mission aircraft, and engineering and construction. In the above-mentioned fields, Raytheon Company is in a leading position.
