Sentinels at Sea Meet the Coast Guard’s newest asset, the Sentinel-class Fast Response Cutter. Designed to replace the aging 110-foot Island-class patrol boat, the Sentinel-class fast response cutter is a key component of the Coast Guard’s offshore fleet that is capable of deploying independently to conduct missions that include port, waterways and coastal security; fishery patrols; search and rescue; and national defense. @uscg @commandantuscg @officialmcpocg @uscglantarea #USCGC #FastResponseC
