About Bayonet 250

Bayonet 250 is Greensea IQ's amphibious tracked vehicle for carrying sensors and mission payloads through beaches, surf zones and shallow coastal water. It supports remote control and autonomous mission software, with camera, forward-looking sonar, navigation and radio equipment. Additional sensor packages can support geophysical survey and explosive-ordnance detection.

A 2023 survey demonstration used the crawler with a towed White River Technologies APEX electromagnetic sensor sled to locate buried objects. Later U.S. Marine Corps procurement included a $5.36 million LEON project award in February 2025 and an additional $3.7 million delivery order in July 2026. These announcements document procurement for defence applications. The commercially offered platform has different battery configurations, so endurance, range and vehicle mass depend on the selected configuration.
