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.

The F135 engine powers all three variants of the F-35 Lightning II fighter aircraft. Pratt & Whitney maintains a global sustainment network supporting 42 bases and 13 ships worldwide. The company has delivered more than 1,500 F135 production engines to customers across 20 allied nations. The upcoming F135 Engine Core Upgrade will leverage the existing sustainment network to provide enhanced capability and fleet readiness.

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.

RTX posts 16% growth but CFO warns of slowdown to 5% in H2

RTX posted 16% organic sales growth and raised its full-year outlook, pushing shares to 52-week highs. However, management confirmed growth will slow sharply to around 5% in the second half, citing difficult year-over-year comparisons, particularly at Pratt & Whitney. The engine division faces a critical trade-off: new engine sales fell 8% this quarter as the company prioritises material flow to repair shops over production. Management is deliberately redirecting resources to fix the troubled GTF engine fleet, achieving a 25% year-to-date reduction in aircraft-on-ground incidents. Whilst credible, the strategy reveals significant operational constraints and caps near-term excitement despite strong quarterly results.
