Raytheon and CET Successfully Test New Low-Cost Long-Endurance UUV Hadalus for US Navy

Raytheon, an RTX business, and Composite Energy Technologies (CET) have successfully demonstrated the undersea launch capabilities of the Hadalus, a new low-cost, long-endurance unmanned undersea vehicle (UUV), during a U.S. Navy exercise. The test, conducted on a Navy undersea test range, marked the first time the U.S. Navy observed this integrated capability in water, showing that a single UUV platform can perform detect, reacquire, and engage functions within one mission. The Hadalus is a 34-foot UUV with a six-foot cross section and over 2,000 nautical miles of endurance, featuring a free-flooded, all-carbon-fiber exoskeleton for strength and payload capacity at a significantly lower cost—roughly one-third to one-fifth of comparable long-endurance vehicles. The companies progressed from a conceptual sketch to a complete prototype in less than 18 months, driven by joint investment in design, launcher integration, sonar, electronics, and full system testing. Raytheon and CET officials emphasized the platform's affordability, speed of development, and potential for scalable, autonomous undersea capabilities.
