The Sentinel-class cutter, also known as Fast Response Cutter due to its program name, is part of the United States Coast Guard's Deepwater program. At it is similar to, but larger than the lengthened 1980s-era s that it replaces. Up to 58 vessels are to be built by the Louisiana-based firm Bollinger Shipyards, using a design from the Netherlands-based Damen Group, with the Sentinel design based on the company's Damen Stan 4708 patrol vessel. The Department of Homeland Security's budget proposal to Congress, for the Coast Guard, for 2021, stated that, in addition to 58 vessels to serve the Continental US, they requested an additional six vessels for its portion of Patrol Forces South West Asia. Planning and acquisition On March 14, 2007, newly appointed United States Coast Guard Commandant Thad Allen announced that the USCG had withdrawn a contract from Lockheed Martin and Northrop Grumman for the construction of an initial flawed design of what would eventually become the Sentinel class. Allen announced that instead of the initial high-tech design Bollinger would build vessels based on an existing design, and the new program would focus more on existing "off-the-shelf" technology. On September 26, 2008, Bollinger Shipyards in Lockport, Louisiana, United States, was awarded US$88 million to build a prototype. The vessel would be the first of a series of 24–34 cutters built to a design largely based on the Damen Stan 4708 patrol vessels from the Netherlands firm the Damen Group. The South African government operates three similar 154 ft Lillian Ngoyi-class vessels for environmental and fishery patrol. The first cutter, , and all future Sentinel-class vessels would be named after enlisted Coast Guard heroes. Bernard C. Webber was launched on Thursday, April 21, 2011, and commissioned on Saturday, April 14, 2012 at the Port of Miami. Bernard C. Webber, and five sister ships, are stationed in Miami, Florida. The second cohort of six vessels is homeported in Key West, Florida, while the third cohort of six vessels is homeported in San Juan, Puerto Rico. On September 26, 2013, Marine Link reported that the Coast Guard had placed orders with Bollinger Shipyards for additional cutters, bringing the number of such cutters ordered by then to thirty. As of June 23, 2016, eight more for a total of 38 FRCs have been ordered, 17 are in service, with six in Miami, Florida; six in Key West, Florida; and five in
