Record defense backlog powers growth as engine risks fade
- RTX has three main engines of the business: Collins Aerospace, Pratt & Whitney, and Raytheon.
- Q2 2026 adjusted sales reached $24.7 billion, up 16 percent organically.
- Total backlog hit a record $289 billion, split between $170 billion commercial and $119 billion defense.
- Raytheon booked nearly $20 billion in the second quarter, driven by major Patriot missile orders.
- The Pratt & Whitney GTF engine powder metal issue is trending better, with grounded aircraft down 25 percent this year.
Defense demand meets supply chain reality
The second quarter of 2026 pushed the bull case forward. RTX reported $24.7 billion in adjusted sales and raised full-year guidance on the back of 16 percent organic revenue growth. The Raytheon segment booked $20 billion in the quarter, including $5 billion for Patriot effectors, proving the defense super-cycle is translating into real backlog.
Beyond defense, the commercial aerospace cycle remains strong. The GTF powder metal issue appears increasingly controlled, with grounded aircraft falling 25 percent this year. Adding to that, the new GTF Advantage engine was certified and will begin service later this year, providing a clear path to durable earnings drivers.
The bear case revolves entirely around execution risk. The massive $289 billion backlog requires a step change in supply chain output. Any failure to scale supplier output for critical components, such as rocket motors or microelectronics, could throttle the growth outlined in the bull case.
The score reflects a balanced setup. RTX has real demand, a record backlog, and fading engine risks. It also has hard operating work ahead to actually deliver the hardware its customers ordered.
Long machines, long service tails
RTX makes complex aerospace and defense hardware. That includes aircraft systems, jet engines, radars, missiles, and missile defense equipment. These products can take years to design, qualify, and build.
The company earns money in two main ways. First, it sells original equipment, such as aircraft parts, engines, and defense systems. Second, it sells service, spare parts, and maintenance for equipment already in use. That installed base is important because an aircraft engine or defense system can need support for decades.
Commercial aerospace sales depend on airlines, aircraft production, and flying activity. Defense sales depend on government budgets, contract awards, export approvals, and program execution.
This model can be powerful, but it can also be unforgiving. A defect in an engine part can ground aircraft and pull cash out of the business. A defense production ramp can stall if suppliers cannot raise output fast enough.
What RTX sells
Collins Aerospace systems
Collins sells avionics, aerostructures, interiors, and other systems for commercial and military aircraft. Demand moves with new aircraft production and airline flight hours.
Pratt & Whitney engines
Pratt & Whitney designs and services aircraft engines for commercial and military users. The GTF engine family is central to the story, both as a long-term installed base and as the source of the powder metal issue.
Commercial engine aftermarket
Engine service is a key profit pool because engines need inspections, parts, and repair over many years. This segment provides a steady stream of high-margin recurring revenue.
Raytheon munitions
Raytheon makes critical missiles and munitions, including Tomahawk, AMRAAM, and the Standard Missile family. Huge defense budgets and recent orders have padded the backlog.
Air and missile defense
Raytheon sells systems tied to land and air defense, including Patriot programs. These were a major driver of the $20 billion in second-quarter bookings.
Naval radars and defense electronics
Raytheon also sells advanced sensors and naval systems, including radar families such as SPY-6. These programs benefit from higher defense budgets.
Three large pillars
Segment mix is based on Q1 2026 total segment net sales before eliminations: Collins $7.6 billion, Pratt & Whitney $8.2 billion, and Raytheon $6.9 billion. Raytheon uses a fiscal quarter end that differs slightly from Collins and Pratt & Whitney.
What could break the plan
GTF powder metal recovery slips
High impact · Medium oddsPratt & Whitney is repairing PW1100 GTF engines. Management says the plan is on track, with grounded aircraft down 25 percent this year and MRO output up 40 percent. However, execution delays could still keep pressure on airlines and cash flow.
Munitions suppliers cannot ramp
High impact · Medium oddsRaytheon demand is historic, but demand does not equal shipments. Management notes the munitions ramp needs a step change in supplier output. Rocket motors, microelectronics, and other constrained parts could cap growth if suppliers fail to deliver on time.
Raytheon margins fade as volume rises
Medium impact · Medium oddsThe risk is that higher production volume brings overtime pay, supplier premiums, or fixed-price cost overruns. If margins fall while sales rise, the defense bull case weakens.
Government and export approvals slow orders
Medium impact · Medium oddsDefense sales depend on budgets, awards, export licenses, and customer approvals. Foreign military and direct commercial sales can be delayed or blocked by government policy, which would hurt the backlog conversion.
Compliance issues remain a drag
Medium impact · Low oddsRTX operates under existing Consent and Deferred Prosecution Agreements tied to past legal and compliance matters. A breach or new investigation could hurt trust and distract management.
In one breath
What does RTX actually do?
RTX is an aerospace and defense company. Collins makes aircraft systems, Pratt & Whitney makes and services engines, and Raytheon makes defense systems such as missiles, radars, and missile defense equipment.
Why is Raytheon important to RTX now?
Raytheon is seeing massive demand for land and air defense systems, naval munitions, and missile programs. In Q2 2026 alone, Raytheon booked nearly $20 billion in awards, driving total backlog to record highs.
What is the GTF powder metal issue?
Pratt & Whitney found a rare condition in powder metal used in some PW1100 GTF engine parts. That requires faster inspections and repairs, which can ground aircraft and create cash costs for RTX.
Is RTX mainly a defense stock or an aerospace stock?
It is both. In Q2 2026, RTX had $170 billion of commercial backlog and $119 billion of defense backlog, so the company is tied to airline activity and government defense spending at the same time.
