RTX (RTX)
Supplies aircraft systems and engines alongside missiles, radars, and air-defense systems.

RTX puts engines and systems on aircraft, then keeps earning from parts and repairs for years; alongside that, it builds missiles, radars and military engines for governments. Military demand now makes up about half the company, while recovering air travel feeds the civilian side. The engine business is also working through a costly inspection problem as defense factories speed up.

Land and Air Defense Systems
Patriot, NASAMS and related missiles and radars defend troops and cities from airborne threats. Sales added about $1.6B in FY2025; the watchpoint is whether factories can turn government orders into timely deliveries.
Competes with SAMP/T NG/Aster (Eurosam/MBDA/Thales) · IRIS-T SLM (Diehl Defence)
In plain English
Picture a shield built in layers: a radar spots what is coming, a control system decides what matters, and a missile tries to knock the threat down. RTX sells governments the pieces for those layers, including Patriot, NASAMS and LTAMDS.
Countries pay for new launchers, radars and missiles, then keep buying replacements and support as the equipment stays in service. Demand is strong, but money arrives only as budgets, export permission and factory capacity line up.
Military Engines
F135 engines power every F-35, with older military engine families adding repair work. Recent F135 production and upkeep awards total roughly $5.1B; future volume depends on aircraft orders, budgets and repair capacity.
Competes with XA102 (GE Aerospace) · F130 (Rolls-Royce)
In plain English
A fighter jet needs both an engine at birth and a repair network for the rest of its life. Pratt & Whitney supplies the F135, the only engine used by the F-35, plus several other military engine families.
Governments pay for new engines, spare parts and years of depot work, where engines are removed and rebuilt. More than 1,300 F135s had been delivered by FY2025, so the installed fleet keeps creating service demand even when new-aircraft schedules move around.
Air and Space Defense Systems
AMRAAM and StormBreaker are aircraft-launched weapons, joined here by warning radars and space-related systems. A factory plan targets at least 1,900 AMRAAMs a year; watch whether testing and parts supply keep pace.
Competes with Meteor (MBDA) · SPEAR (MBDA)
In plain English
These are the weapons and sensors carried by aircraft or used to watch the sky. AMRAAM chases enemy aircraft from beyond a pilot's sight, while StormBreaker strikes targets on the ground; warning radars and space systems help find what needs attention.
U.S. and allied forces order production batches, often through government-to-government sales. RTX earns as each batch is built and delivered, making approval, testing and hard-to-source components just as important as the size of the order.
Military and Defense
Collins supplies the cockpit electronics, secure communications, sensors, power controls and structural pieces inside military aircraft. Sales rose 7% in Q2 2026; watch the schedules of the larger aircraft programs carrying this equipment.
Competes with Link 16 tactical data links (L3Harris) · Tactical Networking products (Viasat)
In plain English
The hidden nervous system inside a military aircraft is Collins' territory: screens for the crew, radios that pass protected information, sensors that notice the surroundings, and equipment that manages power and movement.
Aircraft makers install these parts during a new build, while governments pay again for replacements, upgrades and repairs. That spreads revenue across many platforms rather than one famous weapon, but it also means RTX waits on aircraft production timetables, security approval and permission to sell abroad.
Naval Power
Tomahawk and other missiles sit beside SPY-6 ship radar in this naval line. A seven-year Tomahawk contract is worth $22.9B; the key is expanding factories without letting testing or component supply delay ships.
Competes with SPY-7 (Lockheed Martin) · MdCN/NCM (MBDA) · IRIS-T (Diehl Defence)
In plain English
A navy does not buy only a missile. It needs ship-mounted radar to see far away, weapons to attack or defend, and years of replacement parts and care. RTX supplies that set through Tomahawk, SM-6, ESSM, SPY-6 and related programs.
The U.S. Navy and allied fleets pay through long production agreements and individual orders. Shipyard timing affects when radar goes aboard, while factory expansion determines how quickly missiles can leave the line, so a signed contract turns into sales over many years.
Commercial Engines and EngineWise Services
This is RTX's largest business line, spanning new jet engines, parts and long-term care. RTX's total order book reached $289B by June 2026; watch the pace of GTF inspections and repair-shop output.
Competes with LEAP-1A (CFM International) · Trent 7000/TotalCare (Rolls-Royce)
In plain English
A jet engine sale is the opening move, not the finish line. Pratt & Whitney places GTF, V2500 and other engines on aircraft, then follows them for decades as flying wears down costly parts.
Airlines and aircraft owners pay for replacement parts, one-off repairs or EngineWise agreements that promise ongoing care. More flying means more work. The weak link is the GTF inspection program: affected engines must come off aircraft and pass through crowded repair shops, slowing customers even as those same visits create service work.
Commercial Aviation
Across RTX, the U.S. government, foreign military customers and other governments supplied 53% of sales; Airbus alone supplied 14%. Collins' civil-aircraft line depends on both new-plane output and repair demand from aircraft already flying.
Competes with Honeywell Anthem (Honeywell) · NacelleLife (Safran Nacelles)
In plain English
Open up a passenger aircraft and Collins is tucked almost everywhere: cockpit electronics, electrical power, air and temperature controls, engine coverings, landing equipment, seats and communications.
Aircraft makers pay for those systems when a plane is built. Airlines then return for spare parts, repairs, training and fleet support as the plane keeps flying, much like buying the printer once and ink for years. The result is a business pulled by both factory build rates and miles flown, with safety approval and repair speed controlling when cash arrives.
