## What it is

RTX Corporation is a US aerospace and defense conglomerate headquartered in Waltham, Massachusetts, and listed on the New York Stock Exchange under the ticker RTX. It operates through three segments: Raytheon (guided missiles, radar, and electronic warfare systems), Pratt & Whitney (commercial and military jet engines), and Collins Aerospace (avionics, aircraft interiors, and sensors). At US$88.6 billion in 2025 revenue and a US$268 billion order backlog, RTX ranks among the three largest defense contractors globally, alongside Lockheed Martin and Boeing.

## History

RTX's lineage traces to two legacy US firms. United Technologies Corporation owned Pratt & Whitney (incorporated 1925) and acquired Rockwell Collins in 2018, rebranding it Collins Aerospace. Raytheon Company, founded in Cambridge, Massachusetts in 1922, pioneered microwave radar technology during the Second World War and later became the primary US maker of guided surface-to-air missiles and air-defense systems. The two companies completed a merger of equals on 3 April 2020, forming Raytheon Technologies Corporation; in July 2023, the company shortened its name to RTX. Greg Hayes, the former United Technologies chief executive who engineered the deal, led the combined company until May 2024, when Christopher Calio succeeded him. Calio was elected chairman in 2025.

## Current state

In full-year 2025, RTX posted US$88.6 billion in sales, up 10 percent versus 2024, with free cash flow of US$7.9 billion, up US$3.4 billion year on year. All three segments grew. Pratt & Whitney led at US$32.9 billion (up 17 percent), driven by commercial engine deliveries and geared turbofan aftermarket demand. Collins Aerospace reached US$30.2 billion (up 7 percent). Raytheon grew to US$28.0 billion (up 5 percent). The year-end 2025 backlog totaled US$268 billion, of which US$107 billion was defense. RTX guided 2026 revenue at US$92-93 billion.

In the Raytheon segment, three programs dominate the defense growth story. Patriot air-defense, detailed in [RTX傘下レイセオンがウクライナ向けパトリオット迎撃弾37億ドルの取引を成約、欧州生産を拡大](/ja/n/rtx-patriot-gem-t-europe-2026), is under intense demand across Europe after Russia's 2022 invasion of Ukraine; orders from Ukraine (Germany-funded, US$3.7 billion), the Netherlands (US$627 million), Spain (US$1.7 billion), and Romania (US$168 million) stacked through late 2025 and early 2026. The US Navy's SPY-6 phased-array radar program, expected to equip more than 60 destroyers, drew a US$515 million production contract in June 2026. LTAMDS, the next-generation ground-based radar replacing the aging Patriot sensor set, received a US$1.7 billion US Army contract in September 2025, with Poland as the first international buyer.

On the Pratt & Whitney side, a powder-metal contamination issue in GTF geared turbofan engines, disclosed in August 2023, required thousands of engine removals from narrowbody fleets worldwide and continued to affect delivery schedules and financial provisions through 2026. Raytheon's Coyote reusable interceptor also features in the US Department of Defense's near-term counter-UAS budget, tracked in [国防総省の対ドローン予算が10億ドルに接近、レーザーとマイクロ波は実戦配備へ](/ja/n/army-counter-uas-billion-2027).

## Relationships

RTX's Raytheon segment competes with Lockheed Martin and Northrop Grumman across missiles, radar, and command-and-control systems, though Raytheon holds the prime position on both the Patriot system and its LTAMDS successor. On commercial engines, Pratt & Whitney competes with CFM International (a GE/Safran joint venture) and GE Aerospace for narrowbody and widebody programs. Collins Aerospace faces Honeywell and France's Thales across avionics and interiors. The US Department of Defense accounts for roughly a third of total RTX revenue; NATO-aligned European governments are generating a fast-growing share of the defense backlog, a trend sharply accelerated by the Russia-Ukraine war and European rearmament.

## What to watch

- GTF engine liability: the scope, financial cost, and completion timeline of the powder-metal removal campaign, still running through 2026.
- European Patriot and LTAMDS production pacing, given the growing order queue versus Raytheon's manufacturing capacity.
- SPY-6 delivery progress toward the 60-plus US Navy destroyer target.
- Whether Coyote and other Raytheon counter-drone products capture meaningful share of the US Army's near-US$1 billion counter-UAS budget.
