The US Marine Corps is strengthening its expeditionary mine countermeasure capabilities through the acquisition of additional Bayonet 250 autonomous underwater vehicles developed by Greensea IQ. Designed for operations across deep water, coastal shallows, surf zones, and beaches, the robotic platform enables the detection, identification, and neutralization of underwater explosive hazards without exposing explosive ordnance disposal teams to unnecessary risk. Equipped with open-architecture autonomous navigation software and advanced mission management systems, the Bayonet 250 supports fully unmanned operations in complex littoral environments. The procurement forms part of the Marine Corps’ broader Littoral Explosive Ordnance Neutralization (LEON) program, which continues to modernize underwater explosive threat response through autonomous technologies. By expanding the LEON fleet, the Marine Corps improves operational safety, accelerates mine-clearing missions, and enhances freedom of maneuver during amphibious and coastal operations.
