Composite Energy Technologies

Composite Energy Technologies is a US energy-technology firm named alongside Raytheon as co-developer of HADALUS, an uncrewed underwater vehicle unveiled in reporting published 12 August 2026. The launch put Composite Energy Technologies alongside a defence prime many times its size, credited jointly for a vehicle claimed to run over 2,000 nautical miles submerged at a fraction of the usual cost.

Coverage of the unveiling points, from the company's name, toward a contribution centred on the vehicle's hull and propulsion rather than its sensors, though the two firms have not confirmed the split publicly. The performance figures themselves are launch-day claims rather than results logged by an independent operator, a caveat that applies to the vehicle rather than to Composite Energy Technologies' part in building it.
