The Sentinel-class cutter , also known as the Fast Response Cutter or FRC due to its program name, is part of the United States Coast Guard 's Deepwater program. At 154 feet (46.8 m), it is similar to, but larger than, the 123-foot (37 m) lengthened 1980s-era Island-class patrol boats that it replaces. At least 77 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 Southwest Asia .^[source]Sentinel-class cutter · Lead; only the objects and conditions stated in this passage

The design chosen was 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.^[source]Sentinel-class cutter · Planning and acquisition; only the objects and conditions stated in this passage

In September 2008, Bollinger Shipyards in Lockport, Louisiana, was awarded US$88 million to build the prototype first vessel in its class. That prototype was the first of a projected series of 46.8-meter (154 ft) cutters. In September 2008 the series was expected to comprise a maximum of 24 to 34 cutters but by the time the prototype cutter, which became USCGC Bernard C. Webber , entered service in 2012 the planned number of Sentinel-class cutters had grown to 58. They replaced the 37 remaining aging, 1980s-era 110 ft Island-class patrol boats.^[source]Sentinel-class cutter · Planning and acquisition; only the objects and conditions stated in this passage

In 2017, the Coast Guard announced two FRCs would be stationed in Astoria , Oregon starting in 2021. In 2018, the Coast Guard announced four more would be stationed in San Pedro , California in 2018 and 2019. Also in 2018, the Coast Guard revealed plans to eventually homeport a total of six FRCs in Alaska , with one cutter in Sitka , one in Seward , and two in Kodiak , joining two already operating from Ketchikan . Boston, Massachusetts and St. Petersburg, Florida would eventually be FRC homeports.^[source]Sentinel-class cutter · Planning and acquisition; only the objects and conditions stated in this passage

The vessels are armed with a remote-control Mark 38 25 mm Machine Gun System and four crew-served .50-caliber (12.7 mm) M2HB heavy machine guns . They have a bow thruster for maneuvering in crowded anchorages and channels. They have small underwater fins, for coping with the rolling and pitching caused by large waves. They are equipped with a stern launching ramp , like the Marine Protector-class and the eight failed expanded Island-class cutters. They are manned by a crew of 22. The Fast Response Cutter deploys the 26-foot (7.9 m) Cutter Boat - Over the Horizon (OTH-IV) for rescues and interceptions.^[source]Sentinel-class cutter · Design and construction; only the objects and conditions stated in this passage

Modifications to the Coast Guard vessels from the Stan 4708 design include an increase in speed from 23 to 28 knots (43 to 52 km/h; 26 to 32 mph), 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 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".^[source]Sentinel-class cutter · Design and construction; only the objects and conditions stated in this passage

The cutters have intercepted smugglers carrying large shipments of drugs. In February 2017 Joseph Napier intercepted a shipment of over four tons of cocaine, reported to be the largest drug-bust in the Atlantic Ocean since 1999.^[source]Sentinel-class cutter · Operational histories; only the objects and conditions stated in this passage
