Bayonet Ocean Vehicles was formed following the acquisition of C-2 Innovations' line of undersea crawling robots. Headquartered in Plymouth, Massachusetts, the company shares with Greensea a newly renovated 17,000-square-foot manufacturing facility with waterfront access for year-round testing and training. The robots have been renamed the Bayonet 150, Bayonet 250 and Bayonet 350 vehicles. Their applications include amphibious operations and coastal warfare, such as mine detection and mine clearance.
