RTX is a leading aerospace and defense company formed through the 2020 merger of United Technologies Corporation and Raytheon Company. Headquartered in Arlington, Virginia, the company operates through four principal business segments: Pratt & Whitney, Collins Aerospace, Raytheon Intelligence & Space, and Raytheon Missiles & Defense. RTX designs, manufactures and services advanced systems and technologies that support commercial aviation, military platforms, space exploration, and intelligence operations.
Pratt & Whitney develops and produces aircraft engines for commercial, military and business aviation customers, while Collins Aerospace provides avionics, aerostructures, mechanical systems, and mission-critical services. Raytheon Intelligence & Space delivers sensors, training, cyber and software solutions for defense and civil government agencies, and Raytheon Missiles & Defense offers precision weapons, air and missile defense systems, radars, and command and control technologies.
The heritage of RTX spans nearly a century: Raytheon traces its roots to 1922 with its first invention, the magnetron, while Pratt & Whitney dates back to 1925 as a pioneer in aircraft propulsion. The merger with United Technologies—whose history included the founding of Otis Elevator in 1853 and carrier-based air conditioning in the early 20th century—brought together complementary portfolios to serve a broad range of global customers.
Operating in more than 70 countries, RTX supports commercial airlines, armed forces, space agencies and intelligence communities worldwide. The company emphasizes research and development, sustainability and digital innovation to enhance safety, efficiency and mission readiness. Under the leadership of Gregory J. Hayes as Chairman and Chief Executive Officer, RTX continues to expand its product offerings and global footprint.
