Why this program?
The 45-foot response boat-medium (RB-M) program revitalized the Coast Guard's shore-based boat fleet, delivering improved speed, maneuverability and ergonomics over the 41-foot utility boat and other nonstandard boats it replaced. The RB-M has proven effective in performing Coast Guard missions, including search and rescue; ports, waterways and coastal security; law enforcement; and drug and migrant interdiction. The Coast Guard acquired 174 RB-Ms to replace the 41-foot utility boat class, which was in service from 1973 to 2014. The RB-M program transitioned to sustainment in June 2015 and the Coast Guard completed an RB-M electric retrofit program in May 2017.
