Smarter Underwater Data Collection

We designed our line of small and medium-class UUVs to help extend the Navy's underwater reach while keeping sailors out of harm's way. These autonomous UUVs can be deployed by submarines, surface vessels or two-man teams as part of an interconnected ecosystem of other surface and undersea vessels.

Designing UUVs For The Future Undersea Battlespace

General Dynamics engineers are building smarter UUVs for the naval missions of the future. Some of these advancements include:

  • Connecting UUVs with other vessels using command & control systems
  • Integrating the latest commercial technology, including sonars
  • Leveraging machine learning & AI algorithms 


Our Current Programs

General Dynamics has begun production on unmanned underwater vehicles for the U.S. and Australian Navies. These next-generation UUVs will be deployed on mine-hunting missions all over the world, protecting sailors and their ships.

Knifefish UUV 2019 Testing

Knifefish — A U.S. Navy Mine-Hunting UUV

Knifefish is a medium-class mine countermeasure Unmanned Undersea Vehicle (UUV) intended for deployment from U.S. Navy vessels. Knifefish will reduce risk to personnel by operating in the minefield as an off-board sensor while the host ship stays outside the minefield boundaries. Knifefish is based on the Bluefin-21® UUV.

Project Sea 1778 Bluefin-9 UUV Royal Australian Navy

SEA 1778 — Australian Mine-Hunting UUVs

General Dynamics is delivering Bluefin-9 and Bluefin-12 lightweight UUVs to Thales in support of the Royal Australian Navy’s SEA 1778 program. The autonomous UUVs will help search for, classify and identify sea mines, providing a maritime task group with an initial mine counter-measures (MCM) capability.

Our Products

We offer a range of modular, free-flooded Bluefin UUV products designed for military and scientific missions. Many of our models are customizable, and our proven integration track record includes 70 different sensors on more than 100 vehicles.

Bluefin Robotics Unmanned Underwater Vehicles

Our Bluefin Robotics® UUVs are designed for defense, commercial and scientific customers worldwide. These underwater vehicles can dive up to 14,000 feet below the ocean's surface while collecting data from the sea floor.
