and interceptions. According to Marine Log, modifications to the Coast Guard vessels from the Stan 4708 design include an increase in speed from , fixed-pitch rather than variable-pitch propellers, stern launch capability, and watertight bulkheads. The vessels are built to ABS High Speed Naval Craft rules and some parts of the FRC also comply to ABS Naval Vessel Rules. The vessels meet Naval Sea Systems Command standards for two compartment damaged stability and also meet the Intact and Damage Stability and reserve buoyancy requirements in accordance with the “Procedures Manual for Stability Analyses of U.S. Navy Small Craft". The vessels have space, weight, and power reserved for future requirements which includes weapons and their systems. The cutters have a reduced radar cross-section through shaping. On September 26, 2008, Bollinger Shipyards in Lockport, Louisiana, was awarded US$88 million to build the prototype first vessel in its class. That vessel became USCGC Bernard C. Webber, which is the first of 58 planned Sentinel-class cutters to go into the U.S. Coast Guard fleet to replace their remaining 37 aging, 1980s-era 110 ft Island-class patrol boats. On February 7, 2013, the Department of Homeland Security requested tenders from third party firms to independently inspect the cutters, during their construction, and their performance trials. The bridge is equipped with a handheld device that allows crew members to remotely control the ship's functions, including rudder movement and docking. On July 24, 2014, it was announced that the U.S. Coast Guard had exercised a $225 million option at Bollinger Shipyards for construction through 2017 of an additional six Sentinel-class Fast Response Cutters (FRCs), bringing the total number of FRCs under contract with Bollinger to 30. Later that number was increased to 32 cutters. On May 4, 2016, Bollinger Shipyards announced that the U.S. Coast Guard awarded it a new contract for building the final 26 Sentinel-class fast-response cutters. That brings to 58 the total number of FRCs that the USCG ordered from Bollinger. Acquiring the 58 cutters is expected to cost the federal government $3.8 billion — an average of about $65 million per cutter. On August 11, 2021, it was announced that U.S. Coast Guard had exercised a contract option for 4 additional FRC's, bringing the total number to 64. They will be built at Bollinger's Lockport, Louisiana facility. On March 15, 2022, President Joe Biden signed the Consolidated Appropriations Act for Fiscal Year 2022, which
