## What the business does

RTX sells products and services to airlines, aircraft makers, governments, and other customers. Its three main businesses are Collins Aerospace, which makes aircraft equipment and provides maintenance; Pratt & Whitney, which makes and services aircraft engines; and Raytheon, which makes missiles, air-defense systems, radar, and other military equipment. It earns money from equipment sales and from later work such as spare parts, repairs, and maintenance.

### How it makes money

- **Pratt & Whitney** (35.5% of segment sales (six months ended June 30, 2026)) — Sells commercial and military aircraft engines and earns further revenue from spare parts, engine repairs, and maintenance. Share is calculated from segment sales before eliminations between businesses.
- **Collins Aerospace** (32.9% of segment sales (six months ended June 30, 2026)) — Sells aircraft equipment and earns revenue from spare parts, repairs, maintenance, and other services. Share is calculated from segment sales before eliminations between businesses.
- **Raytheon** (31.6% of segment sales (six months ended June 30, 2026)) — Sells missiles, radar, air-defense equipment, and related services, mainly to government customers. Share is calculated from segment sales before eliminations between businesses.

### Products

- **Collins aircraft equipment and cabin interiors** — Equipment used on aircraft, including flight controls, landing gear, brakes, communications and navigation equipment, lighting, and passenger seats and galleys.
- **Collins aircraft maintenance and connected aviation services** — Spare parts, repairs, overhauls, engineering support, and training for aircraft, as well as communication networks and equipment used by airports and air traffic controllers.
- **Pratt & Whitney commercial engines and maintenance** — Engines for passenger, business, regional, and general aviation aircraft, including the geared turbofan engine family, plus spare parts, repairs, and maintenance.
- **Pratt & Whitney military engines and auxiliary power units** — Engines for military aircraft, including the F135 engine used in all versions of the F-35 fighter, and auxiliary power units that provide aircraft with power when their main engines are not running.
- **Raytheon missiles and air-defense equipment** — Missiles and related equipment for intercepting aircraft and missiles, including Patriot, Standard Missile, AMRAAM, and Tomahawk products.
- **Raytheon radar, sensors, and space equipment** — Radar and other detection equipment, satellite components, and systems used to collect information and help military customers track and respond to threats.

### Customers

- The United States government buys defense products and services through contracts with RTX businesses.
- Foreign governments buy military equipment directly or through government-to-government sales arranged by the United States government.
- Commercial airlines and other aircraft operators buy aircraft equipment, engines, spare parts, repairs, and maintenance, often through long-term service agreements.
- Aircraft manufacturers, including Airbus and Boeing, buy engines and aircraft equipment for installation on new aircraft.
- Aircraft leasing companies buy engines and related services for aircraft they own or lease.
- Maintenance and repair companies and independent distributors buy parts and services for use in aircraft repairs and upkeep.

### Competitors

- GE Aerospace (GE) — Aircraft engines and related maintenance services.
- Honeywell International (HON) — Aircraft equipment, avionics, and related services.
- Safran (SAF) — Aircraft engines, equipment, and maintenance services.
- Lockheed Martin (LMT) — Military aircraft, missiles, and air- and missile-defense programs.
- Northrop Grumman (NOC) — Missiles, radar, space equipment, and other military programs.
- Boeing (BA) — Aircraft equipment and defense programs; Boeing is also an important customer for Collins Aerospace.

### What it depends on

- A substantial part of the business depends on United States government contracts, defense budgets, contract performance, and government approvals for some international sales.
- Commercial aerospace sales depend on airline activity and the production and delivery schedules of aircraft manufacturers.
- Some aircraft equipment and engines are selected for particular aircraft designs, linking later parts and service revenue to the number of those aircraft in use.
- RTX relies on a global supply chain for materials and components; it reports some single-source suppliers and reliance on foreign sources for certain raw materials.
- Pratt & Whitney's F135 engine is the sole engine used in the F-35 aircraft.

### What could go wrong

- A rare condition in powder metal used in certain engine parts requires accelerated inspection of Pratt & Whitney's PW1100G-JM engine fleet, which powers Airbus A320neo aircraft.
- Shortages, delays, or higher prices for materials and components—including rare earth elements and microelectronics—can hold up production and raise costs; the company says supply disruptions have affected its performance.
- Government contracts and defense sales are subject to procurement rules, audits, and export approvals. RTX also remains subject to compliance obligations under agreements and orders resolving earlier investigations; a breach could lead to further legal or business consequences.
