HUGIN at US Navy Facilities

HUGIN is Kongsberg's family of free-swimming autonomous underwater vehicles, and the registry entity is scoped to the HUGIN AUV rather than Kongsberg, the large Norwegian sensor and systems conglomerate that makes it. HUGIN passes the AI-as-primary test despite its corporate parentage because it is a genuine autonomous undersea vehicle with in-mission onboard processing, including autonomous pipe-tracking, terrain-relative navigation, and automated target recognition, not a sensor package; the HUGIN Superior variant is rated to full ocean depth with more than 70 hours of endurance and navigation accuracy better than 0.04 percent of distance travelled.

The registry records it at production maturity: twelve navies operate HUGIN for mine countermeasures, intelligence preparation of the operational environment, seabed warfare, and survey, it passed US Navy acceptance tests in early 2025, and Kongsberg began HUGIN production in the United States in 2025. Its autonomy is strong at the vehicle level, with onboard autonomy, automated target recognition, and terrain-relative navigation, and the sensor-package and legacy risk applies to the parent corporation rather than to HUGIN, a distinction the entity scoping resolves by recording the HUGIN AUV rather than Kongsberg itself. The twelve-navies figure is vendor-stated and the exact fielded count and per-customer details are not independently audited.
