The Response Boat-Medium (RB-M) will provide greater effectiveness on Search And Rescue missions. It will also be a more capable platform for Enforcement of Laws and Treaties, Ports, Waterways, and Coastal Security, Defense Operations, Recreational Boating Safety, and Marine Environmental Protection missions. Interoperability of the RB-Ms with other Coast Guard assets will greatly enhance the overall Coast Guard command and control in the Coastal Zone..
