Keeper-class cutters serve the Coast Guard in a variety of missions and are tasked with maintaining aids to navigation (ATON), search and rescue (SAR), law enforcement (LE), migrant interdiction, marine safety inspections, environmental protection and natural resources management. Keeper-class cutters are also used for light ice breaking operations. These vessels are 175' long and replaced the WWII era 157' and 133' tenders. The new class of buoy tender cut crew size from 35 and 26, respectively, to 25 saving the already cash strapped Coast Guard financial and personnel resources.
