Bayonet AUGVs

Versatile, Durable, and Built for Extreme Conditions

The Bayonet series of Autonomous Underwater Ground Vehicles (AUGVs) represents the pinnacle of mission-ready versatility for complex subsea and amphibious operations. These rugged vehicles thrive in environments where traditional ROVs and AUVs face limitations, offering unmatched stability and payload capacity for a range of defense, commercial, and scientific applications.

Mission Capabilities in Harsh Environments:

Bayonet AUGVs operate seamlessly from the seabed to the surf zone and onto shore, making them ideal for nearshore and amphibious operations such as underwater beach surveys, unexploded ordnance (UXO) detection, and coastal mapping. They are engineered to maintain operational stability even in high-energy surf zones, capable of withstanding wave heights up to 6 feet.

Key Features:

  • Amphibious Performance: Designed for surf zones and depths up to 100 meters.
  • Payload Flexibility: A large open deck and modular design allow for the integration of payloads such as forward-looking sonar, magnetometers, and sub-bottom profilers.
  • Rugged Construction: Built to endure extended missions in extreme conditions.

UXO Inspection and EOD Applications:

The Bayonet AUGV is widely utilized for UXO inspection, providing defense operators with a reliable, autonomous tool for detecting and mapping underwater hazards. Its precise navigation system and compatibility with advanced sensor payloads ensure enhanced situational awareness during EOD operations, improving safety and operational success.
