Raytheon and CET Successfully Test Hadalus UUV with Weapon Launch for US Navy
Raytheon and Composite Energy Technologies (CET) successfully demonstrated the Hadalus, a low-cost, long-endurance unmanned undersea vehicle (UUV), during a US Navy exercise. The 34-foot, carbon-fiber UUV completed missions on a Navy undersea test range, proving its ability to autonomously detect, reacquire, and engage targets from beneath the surface. Developed from concept to prototype in under 18 months, the Hadalus costs one-third to one-fifth of comparable vehicles, marking a significant advancement in autonomous undersea warfare capabilities.

Raytheon and CET demonstrate HADALUS drone submarine with weapon launch capability for US Navy
Raytheon and Composite Energy Technologies (CET) have successfully demonstrated the HADALUS uncrewed undersea vehicle (UUV) during a US Navy exercise, marking the first time the service has seen an integrated launch capability from a submerged drone. The 34-foot-long vehicle features a free-flooded carbon fiber exoskeleton, allowing lighter construction and lower cost—roughly one-third to one-fifth the price of comparable long-endurance UUVs. HADALUS completed missions on a Navy test range, demonstrating detect, reacquire, and engage functions within a single mission. The companies developed the prototype from concept to water demonstration in under 18 months using their own investment. The vehicle's ability to autonomously find and engage targets represents a significant step beyond current undersea drones, which typically only survey and report. The UK's Royal Navy is pursuing similar capabilities through Project Cetus and autonomous mine countermeasures systems, with the 2025 Strategic Defence Review calling for pairing crewed submarines with UUVs for Atlantic Bastion operations.
Raytheon and Composite Energy Technologies test HADALUS drone submarine that launches weapons
Raytheon and Composite Energy Technologies have demonstrated a new uncrewed undersea vehicle, HADALUS, launching weapons from beneath the surface during a US Navy exercise. This is the first time the Navy has seen this integrated capability in the water. The 34-foot-long vehicle has a carbon fibre exoskeleton, a range of over 2,000 nautical miles, and is designed to cost a third to a fifth of comparable long-endurance vehicles. It completed missions on a Navy undersea test range, proving its ability to detect, reacquire, and engage targets autonomously within a single mission. The companies developed the vehicle from a conceptual sketch to a water-tested prototype in under 18 months using their own investment. The demonstration marks a step beyond current undersea drones, which typically only search, survey, and report, by enabling autonomous target engagement.

Raytheon and CET Successfully Test New Low-Cost Hadalus UUV for U.S. 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.

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 34-foot UUV, with a six-foot cross section and over 2,000 nautical miles of endurance, completed a series of at-sea missions on a Navy undersea test range, proving its submerged launch and autonomous mission capabilities. This marks the first time the U.S. Navy has seen this integrated capability in the water, pointing toward a future where a single unmanned undersea platform can perform detect, reacquire, and engage functions within one mission. The free-flooded, all-carbon-fiber exoskeleton delivers exceptional strength and payload capacity while enabling a significantly lower-cost architecture, designed to cost roughly one-third to one-fifth of comparable long-endurance vehicles. In less than 18 months, the companies progressed from a conceptual sketch to a complete prototype successfully demonstrated in water.
