The United States Marine Corps has awarded Greensea Systems, Inc., operating as Greensea IQ, a $3.7 million task order for four additional Bayonet 250 Autonomous Underwater Ground Vehicles.
The vehicles will further support the Littoral Explosive Ordnance Neutralization Family of Systems, a critical capability for mine countermeasures and subsea threat mitigation in the littoral battlespace.
The task order was issued under an existing multi-year Indefinite Delivery/Indefinite Quantity contract and continues the Marine Corps’ procurement of Greensea IQ’s Bayonet Autonomous Ground Vehicles.
The US Marine Corps was the earliest adopter of Bayonet Autonomous Underwater Ground Vehicles for mine warfare. Greensea IQ also reports engagement with multiple other agencies and allied organizations.
Greensea IQ describes the Bayonet 250 as the adaptable workhorse of its autonomous underwater ground vehicle lineup. According to the company, Bayonet AUGVs are the only commercially ready unmanned amphibious robots capable of navigating from the deep ocean through the surf zone and onto land.
This capability allows the vehicles to operate across seabed, littoral, and coastal environments.
Powered by Greensea IQ Core open-architecture autonomy software and Bayonet Workspace, the Bayonet 250 AUGV is designed for high-risk unmanned subsea reacquisition and threat-neutralization missions.
The vehicles form part of the wider Greensea IQ Bayonet portfolio, which includes remote navigation packages, mission-execution software, and training simulators. The technology suite is designed to provide flexible capabilities across environments ranging from the surf zone to deep-sea terrain, supporting safer and more efficient naval missions.
Greensea IQ has spent 20 years developing autonomous maritime technology for complex and dangerous environments. Its autonomy, navigation, and software technologies support commercial and defense operators around the world.
