About RTX Corporation

RTX Corporation is a U.S. aerospace and defense manufacturer organized around three operating segments: Collins Aerospace, Pratt & Whitney, and Raytheon. Collins Aerospace produces avionics, interiors, mechanical systems, and mission systems for commercial and military aircraft. Pratt & Whitney designs and manufactures aircraft engines, including the geared turbofan family used on narrowbody airliners and the F135 engine powering the F-35 fighter. Raytheon builds integrated defense systems, missiles, radars, and air and missile defense platforms such as Patriot, NASAMS, and the SM-family interceptors. Revenue splits roughly evenly across the three segments, with commercial aftermarket work on engines and components typically generating a disproportionate share of segment profit relative to original equipment sales.

Serious holders track a defined set of structural questions. Customer concentration is high: the U.S. government and a small number of large airframers and airlines drive most bookings, so Department of Defense budget cycles, foreign military sales approvals, and Boeing and Airbus build rates all matter. The Pratt geared turbofan powder-metal inspection program remains a multi-year overhang affecting cash flow, customer compensation, and fleet availability. Investors also watch defense backlog composition, fixed-price development risk, ITAR and export control exposure, supply chain constraints on castings and forgings, S&P 500 index weight, dividend and buyback cadence, pension positioning, and governance items including board composition and executive compensation tied to program milestones.

The company in its current form was created in April 2020 through the merger of United Technologies Corporation's aerospace businesses with Raytheon Company, initially named Raytheon Technologies and rebranded RTX in 2023. United Technologies itself traced to a 1934 reorganization of United Aircraft and Transport, and had built its aerospace franchise around Pratt & Whitney and, through the 2018 Rockwell Collins acquisition, an expanded Collins Aerospace. As part of the merger transaction, United Technologies spun off Carrier and Otis as independent public companies. Headquartered in Arlington, Virginia, RTX now operates as three reporting segments after simplifying an earlier four-segment structure that had separately housed Raytheon Intelligence & Space and Raytheon Missiles & Defense.

Revenue comes through two mechanically distinct channels. Defense sales run largely on multi-year U.S. and allied government contracts, a mix of cost-plus development work and fixed-price production, funded through congressional appropriations and foreign military sales cases coordinated with the State Department. Commercial aerospace revenue comes from selling engines and systems to Boeing, Airbus, and other airframers, then earning higher-margin aftermarket revenue over decades through spare parts, maintenance, and long-term service agreements tied to the installed fleet. Competitive position rests on certified technology, installed base, and program incumbency against rivals including GE Aerospace, Safran, Lockheed Martin, and Northrop Grumman. International customers contribute a meaningful minority of sales, concentrated in NATO members and Gulf and Indo-Pacific allies.
