Which defense contractors specialize in autonomous underwater vehicles?

Several major defense contractors and specialized maritime technology firms focus on the research, development, and production of Autonomous Underwater Vehicles (AUVs) and extra-large uncrewed undersea vehicles (XLUUVs) for military applications.

• Boeing — A major prime contractor in this space, Boeing developed the Orca XLUUV for the U.S. Navy. The Orca is an extra-large, pier-launched autonomous submarine designed for long-duration missions, seabed warfare, and intelligence, surveillance, and reconnaissance (ISR).
• General Dynamics Mission Systems (Bluefin Robotics) — General Dynamics builds a wide family of modular AUVs through Bluefin Robotics. Their portfolio includes tactical systems like the Bluefin-21 (capable of deep-water and under-ice navigation) and the Knifefish surface-mine countermeasure UUV built for the U.S. Navy.
• Northrop Grumman — Northrop Grumman focuses heavily on advanced underwater autonomy, highlighted by its development of the Manta Ray UUV prototype for DARPA. The vehicle is designed for long-range, energy-saving operations featuring a unique capability to anchor to the seafloor and hibernate in low-power states.
• Lockheed Martin — Lockheed Martin has extensive experience in unmanned maritime systems and competed directly in the initial design phases of the Navy’s extra-large AUV (XLUUV) pipeline. They build various autonomous sub-surface technologies and vehicle management systems.
• Teledyne Marine (Teledyne Gavia) — A prominent name across defense, commercial, and scientific sectors, Teledyne provides low-logistics, man-portable AUVs, modular survey autonomous vehicles (such as the Gavia AUV), and long-endurance autonomous underwater gliders used for persistent naval monitoring.
• Exail — Formed via the merger of ECA Group and iXblue, Exail specializes in cutting-edge maritime robotics, including autonomous underwater drones, navigation systems, and mine-hunting AUVs utilized by various international defense forces.

If you'd like to narrow this down, let me know if you are interested in:

• Specific size classes (man-portable vs. extra-large XLUUVs)
• Specific mission profiles (mine countermeasures, mapping, or strike/surveillance)
• International vs. U.S. defense markets

Several defense contractors have substantial autonomous underwater vehicle (AUV/UUV) capabilities. The main players include:

• HII (Huntington Ingalls Industries) — Its REMUS family is one of the most established military AUV lines, spanning compact systems such as REMUS 100/300 through larger long-endurance vehicles such as REMUS 6000. HII says it has delivered more than 700 REMUS vehicles to over 30 countries.
• General Dynamics Mission Systems / Bluefin Robotics — Produces the Bluefin family of autonomous UUVs, including Bluefin-9 and Bluefin-12, with applications including mine countermeasures and undersea intelligence.
• Kongsberg Discovery — Its HUGIN AUV family is particularly prominent in deep-water and long-endurance applications. HUGIN systems support mine countermeasures, seabed warfare, mapping and reconnaissance; Kongsberg has also received U.S. Defense Innovation Unit work involving HUGIN systems.
• Boeing — Develops very-large, long-endurance unmanned underwater vehicles, most notably Echo Voyager, putting it in a different segment from smaller survey and mine-hunting AUVs.
• L3Harris Technologies — Has the Iver family of autonomous underwater vehicles and associated sensors, communications and mission systems.

A useful way to distinguish them

If you're looking at the defense-industrial market specifically, HII, General Dynamics, and Kongsberg stand out for mature, dedicated AUV product families, while Boeing is particularly relevant to the large/extra-large UUV segment. These are descriptive distinctions based on their publicly documented programs, not a ranking.

Several major defense contractors and maritime technology companies specialize in autonomous underwater vehicles (AUVs) and extra-large uncrewed undersea vehicles (XLUUVs) for military intelligence, reconnaissance, and seabed warfare.
