What believers are saying

  • RTX raised 2026 sales guidance to $95–$96 billion after Q2 organic growth.
  • Tomahawk output rises toward 1,000 annually, with $22.9 billion Navy funding secured.
  • Commercial aftermarket sales rose 18%, boosting cash flow as engine deliveries recovered.

What critics are saying

  • Pratt & Whitney’s GTF defects grounded airline fleets and keep Airbus threatening damages.
  • Airbus seeks compensation in 2026, and ITA Airways weighs litigation over Pratt faults.
  • Powder-metal GTF repairs still cost RTX about $150 million quarterly, pressuring margins.

What makes RTX unique

  • RTX combines Pratt engines, Collins avionics, and Raytheon missiles across one platform.
  • RTX backlog reached $289 billion in Q2 2026, spanning defense and commercial demand.
  • Raytheon’s Tomahawk contract and classified awards cement RTX’s scale in munitions.

RTX's Raytheon wins $22.9B contract to accelerate Tomahawk missile production

Raytheon, an RTX business, has secured a seven-year, $22.9 billion contract from the US Navy to accelerate production of Tomahawk cruise missiles. The agreement, part of the Department of War's Arsenal of Freedom initiative, will support ramping annual production to over 1,000 missiles. RTX has already tripled Tomahawk deliveries in the first half of 2026 compared to the same period in 2025. The contract will enable the company to expand capacity and work with hundreds of suppliers nationwide to scale output. Tomahawk cruise missiles provide long-range strike capabilities, allowing the Navy to target hostile forces from hundreds of miles away across multiple launch platforms.

RTX's Raytheon demonstrates new unmanned undersea vehicle with 2,000 nautical mile range

Raytheon, an RTX business, and Composite Energy Technologies have successfully demonstrated HADALUS, a new unmanned undersea vehicle, during a US Navy exercise. The 34-foot UUV completed at-sea missions whilst submerged, marking the first time the Navy has witnessed this integrated capability in water. HADALUS features a carbon-fibre design with over 2,000 nautical miles of endurance. The vehicle costs roughly one-third to one-fifth of comparable long-endurance vehicles. The companies progressed from conceptual sketch to working prototype in under 18 months. The demonstration showcased the UUV's ability to perform detect, reacquire, and engage functions within a single mission. "By tightly coupling design, integration and at-sea experimentation, we've proven we can bring new autonomous solutions to the fleet quickly and cost-effectively," said Jen Gauthier, vice president at Raytheon.

RTX's Raytheon installs first SPY-6(V)4 radar array at Wallops Island for US Navy destroyer upgrade

Raytheon, an RTX business, has installed the first SPY-6(V)4 radar array at the Surface Combat Systems Center at Wallops Island, Virginia. The installation marks a milestone for the US Navy's Flight IIA Destroyer modernisation programme. The land-based test facility will support radar testing and power system integration before installation on USS Pinckney (DDG 91), the first ship scheduled for the SPY-6(V)4 backfit from late 2026 to 2028. Testing will begin later this year and continue through mid-2028. SPY-6 variants are already onboard two commissioned Navy ships, with 11 additional vessels undergoing testing. Over the next decade, more than 50 Navy ships are expected to deploy SPY-6 radars. Raytheon has invested $800 million in manufacturing facilities and aims to double production by 2028.

US Pentagon signs seven-year deals with L3Harris and Lockheed Martin to expand missile defense production

The US Defense Department announced two seven-year agreements with L3Harris Technologies and Lockheed Martin on 27 July to expand propulsion capacity for Patriot and THAAD interceptors, addressing missile defence system shortages driven by Iran tensions. RTX also benefits as a key contractor and supplier for these systems. L3Harris is up 3% this year, whilst RTX and Lockheed Martin have gained more than 17% and 19% respectively. Lockheed reported Q2 revenue of $20.1 billion, up 11% year over year, with a record backlog of $230 billion. Through its Aerojet Rocketdyne business, L3Harris supplies solid-rocket motors for THAAD and Patriot missiles, benefiting from demand regardless of contract awards.
