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.

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.

RTX's Pratt & Whitney has secured a nearly $1.3 billion contract for F135 engine spare parts. The Indefinite Delivery, Indefinite Quantity contract will fund fiscal year 2026 requirements for initial spare parts, deployable packages, depot lay-ins and support equipment for US and international F-35 customers. 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.
