Would you like to explore the differences in mission capabilities (such as mine-hunting vs. long-range strategic surveillance) or dive deeper into a specific contractor's vehicle lineup?

Several defense contractors have substantial expertise in autonomous underwater vehicles (AUVs), also called unmanned underwater vehicles (UUVs). The strongest names depend on whether you're interested in mine countermeasures, surveillance, submarine-launched systems, or large/extra-large vehicles.

The standouts

HII is probably the clearest answer if by "specialize" you mean a company whose business includes a major dedicated AUV product line. Its REMUS family has been in service for 25 years, with more than 700 vehicles sold, and HII describes itself as the world's largest producer of UUVs. Its newer REMUS 130 entered delivery in 2026, while its Lionfish program is scaling for the U.S. Navy.

General Dynamics Mission Systems is another particularly important U.S. player through Bluefin Robotics. Its Bluefin portfolio includes the Bluefin-9, -12, -21 and HAUV, with applications ranging from mine hunting to undersea inspection.

Anduril is especially interesting if you're looking at the newer generation of large autonomous systems. In March 2026, the company announced that the U.S. Navy and Defense Innovation Unit selected it for the Combat Autonomous Maritime Platform (CAMP) XL-AUV effort. Anduril says its undersea vehicles have accumulated more than 42,000 km of mission distance.

Kongsberg is a major international specialist, particularly through its HUGIN AUV family. Its systems combine autonomous navigation, sonar and seabed sensing and have applications in both defense and commercial subsea work.

Saab is particularly relevant to naval applications such as mine warfare and anti-submarine warfare, while Boeing's Echo Voyager is notable for the extra-large, long-endurance end of the UUV market.

If you're looking at this from an investment, competitive-intelligence, or defense procurement perspective, I'd divide the market into three tiers: HII/GDMS for established U.S. AUV production, Kongsberg/Saab/Teledyne for mature international AUV expertise, and Anduril/Boeing for the emerging XL-AUV segment.

If you mean defense companies with substantial, purpose-built autonomous underwater vehicle (AUV/UUV) capabilities, the leading names include:

The companies I'd put in the top tier

Anduril is probably the most notable current entrant if you're specifically interested in large autonomous combat/mission vehicles. Its Dive-LD and Dive-XL are designed around long endurance and modular payloads, and in March 2026 the U.S. Navy and Defense Innovation Unit selected Anduril for an XL-AUV effort.

General Dynamics Mission Systems has one of the deepest U.S. pedigrees in operational AUVs through its acquisition of Bluefin Robotics. Its Bluefin vehicles include the Bluefin-9/12/21, while Knifefish is a Navy mine-countermeasure UUV based on the Bluefin-21.

Kongsberg is particularly strong in deep-water autonomous systems. Its HUGIN family has more than 30 years of autonomous undersea development and is used for defense missions including mine countermeasures and seabed warfare.

Saab is another major specialist, particularly in European naval applications. Its AUV62-MR is explicitly designed for autonomous mine-countermeasure missions, while Saab is also developing a larger LUUV for Sweden.

HII is important because its REMUS family has a long operational history with navies and other government customers. L3Harris and Teledyne are also significant players in smaller and medium AUVs, particularly sensing, survey and mine-warfare applications.

If you're looking at this from an investment/competitive-intelligence perspective, I'd divide the market into (1) XL-AUVs such as Dive-XL, (2) military/tactical UUVs such as Knifefish and REMUS, and (3) deep-water survey/ISR AUVs such as HUGIN—the competitive landscape looks quite different in each segment.

Several major defense contractors and specialized technology firms focus on the development, manufacturing, and integration of Autonomous Underwater Vehicles (AUVs) and Unmanned Undersea Vehicles (UUVs) for military intelligence, surveillance, reconnaissance (ISR), and mine countermeasures.

• Saab — Leverages its deep legacy in torpedo and submarine engineering to build advanced autonomous ocean drones and AUV families (such as the AUV62-MR and Sabertooth IMR platforms) designed for surveillance and seabed infrastructure protection.
• Teledyne Marine (Teledyne Gavia / Webb Research) — Produces turnkey survey AUVs like the Gavia alongside autonomous underwater gliding vehicles (Slocum gliders) utilized heavily for both oceanographic research and defense environmental profiling.

If you'd like to narrow this down, let me know:

• Are you looking for extra-large strategic UUVs or man-portable tactical AUVs?
• Do you need information focused on a specific geographic region or navy?

If you mean defense companies with substantial, purpose-built autonomous underwater vehicle (AUV/UUV) programs, rather than companies that merely supply underwater components, these are among the most important:

The standouts

HII is probably the clearest specialist if you're looking for a company whose core business includes large-scale production of operational AUVs. Its REMUS family has been deployed by more than 30 countries, and HII describes itself as the world's largest producer of UUVs. Its current portfolio ranges from relatively small REMUS vehicles to 6,000-meter-depth systems.

Anduril is particularly interesting for the newer generation of large, software-defined autonomous submarines. Its Dive-LD can operate to 6,000 m and for up to about 10 days, with a large modular payload volume. In 2026, the U.S. Navy/DIU selected Anduril for an XL-AUV effort under the CAMP program.

L3Harris is another major U.S. player. Its Iver family covers smaller AUVs through the Iver4 900, including a torpedo-tube-launch/recovery configuration intended for submarine operations.

Kongsberg is arguably the strongest international competitor in deep-water AUVs. Its HUGIN family has more than 30 years of operational experience, with vehicles rated to 6,000 m. Kongsberg has also delivered HUGIN systems to the U.S. Navy through a DIU program and is establishing U.S. production.

Saab has a particularly broad underwater portfolio, including AUV62 for ASW training, Sabertooth for deep-water autonomous operations, and Double Eagle systems for mine warfare.

Boeing and Lockheed Martin are more notable for very-large military UUVs than for the commercial-style AUV market. Boeing's Orca is designed for monthslong autonomous missions and carries a large modular payload bay. www.boeing.com Lockheed Martin is developing newer concepts such as the Lamprey multi-mission autonomous undersea vehicle.

If you're looking specifically at the U.S. defense market

I'd divide the landscape roughly like this:

• AUV specialist / production leader: HII
• New-generation autonomous/AI undersea systems: Anduril
• Established small/medium AUVs: L3Harris
• Deep-water AUV specialist: Kongsberg
• XLUUV / strategic autonomous submarine: Boeing
• Large military UUV + undersea systems: Lockheed Martin
• European naval AUV leader: Saab

If your interest is investment/competitive analysis, the most interesting comparison is probably HII vs. Anduril vs. L3Harris vs. Kongsberg, because they occupy substantially different positions in the AUV market.
