According to the US Coast Guard, "While primarily a Search and Rescue (SAR) asset when the 41' UTB was first fielded, the evolution of missions has increased the requirement to perform many missions including Recreational Boating Safety (RBS), Marine Environmental Protection (MEP), Enforcement of Laws and Treaties (ELT), Ports, Waterways, and Coastal Security (PWCS) and Defense Operations (DO), including those traditional missions associated with Homeland Security." In August 2010 the US government donated three boats for drug interdiction to Albania, where they are known as the Archangel class.
