Company History
Founded 2020 in Arlington, Virginia
In 1945, an engineer named Percy Spencer was working at Raytheon, building highly powerful radar equipment for the US military. While standing next to an active radar set, he noticed that a peanut cluster bar in his pocket had completely melted. Highly curious, he held a bag of popcorn next to the radar, and it immediately popped. Raytheon realized their deadly military radar technology could instantly cook food. They patented the 'microwave oven', completely transforming a specialized defense contractor into a massive consumer electronics titan alongside their weapons division.
Invented the microwave oven (via Percy Spencer's cavity magnetron research) and missile defense systems before merging with UTC in 2020 to form RTX.
Encompassed Pratt & Whitney, Collins Aerospace, Carrier, and Otis before completing the aerospace merger with Raytheon.
Marshall co-founded the American Appliance Company (renamed Raytheon in 1925) and served as its first president, organizing early venture financing.
Bush co-founded Raytheon in 1922 and guided its research trajectory toward high-frequency electronics, radar, and advanced defense systems.
Smith invented the helium rectifier tube (the S-Tube), which allowed radios to run directly on household AC electricity without expensive batteries.
Rentschler designed the air-cooled Wasp radial engine and formed United Aircraft Corporation (later United Technologies, merged into RTX in 2020).
American Appliance Company, later Raytheon, was founded in Cambridge, Massachusetts.
Frederick Rentschler founded Pratt & Whitney Aircraft and built the Wasp engine franchise.
United Technologies acquired Rockwell Collins, creating Collins Aerospace and expanding aircraft systems scale.
Raytheon Company and United Technologies completed their merger after UTC spun off Carrier and Otis.
Raytheon Technologies adopted the RTX name while keeping Collins Aerospace, Pratt & Whitney, and Raytheon as operating businesses.
RTX reported $88.6 billion in 2025 sales and a $268 billion backlog across commercial and defense work.
attempting to dominate the global commercial aviation supply chain and expand its flight systems scale, United Technologies (prior to the Raytheon merger) executed a strategic $30 billion acquisition of Rockwell Collins.
To violently address cyclical volatility in both defense and commercial aviation, United Technologies executed a strategic 'merger of equals' with the legendary defense contractor Raytheon.
Since its establishment in 2020, RTX Corporation expanded from an early-stage venture into a recognized leader in Aerospace and Defense, overcoming key market challenges.
Over its history, RTX Corporation executed decisive strategic pivots toward scalable monetization and digital distribution, securing its current market leadership.
By continually modernizing operations and embracing workflow automation, RTX Corporation maintains resilience through changing technological and economic cycles.
