The USCG wants to buy 58 Fast Response Cutters (FRC), and these Sentinel Class boats are sorely needed by an overstretched US Coast Guard. When the Island Class refurbishment program was terminated in June 2005, 41 Island Class vessels like the USCGC Sanibel, above, still plied US and international waters.
It has been clear for some time that the US Coast Guard needed a massive modernization effort, after years of neglect. Former Commandant Collins had been sounding this clarion call throughout his 4-year stint, and elected representatives had been paying attention.
Appendix B details the failure of the initial FRC program, which aimed to field a composite-hull cutter to replace the Island Class. The Sentinel Class will be built to ABS High-Speed Naval Craft Guide specifications, which has meant adding watertight bulkheads.
The boats and their crews of 22-24 personnel are clearly intended for near-shore activities.
All of these boats will be named after enlisted Coast Guard heroes, who distinguished themselves in USCG or military service. The Coast Guard sees the Caribbean and the Gulf of Mexico as its top priorities, and has sent the first Sentinel Class cutters to those regions.
This option brings the total number of FRCs under contract with Bollinger to 30, with 10 delivered so far, and the total value of the contract to nearly $1.38 billion. Machinery Technician First Class Charles Sexton gave his life in 1991, during a rescue operation near Washington State’s treacherous Columbia River bar. This 6-ship purchase was one component in $9.3 billion of US DHS discretionary funding allocated to the Coast Guard for FY 2013. Fireman First Class Paul Leaman Clark served as a landing boat engineer during the Allied invasion of North Africa in November 1942. Margaret Norvell was a lighthouse keeper near New Orleans, and is credited with a number of daring rescues during her 41 years of service. The boat is named after Coast Guard Engineman and ammunition specialist First Class Robert J. She will serve from Miami, but Tampa was the site of the Coast Guard’s worst peacetime loss of life in 1980, when the oil tanker Capricorn hit CGC Blackthorn and ripped the buoy tender open with its anchor. This option brings the total number of FRCs ordered to 18 of a possible 34 boats, and the total value of the contract so far to nearly $880 million.
The RDLP will provide the Coast Guard with the required design data, drawings, materials list, and technical and testing information necessary to allow a competition for the follow-on Phase II FRC production contract. As the unofficial CGBlog points out, The Coast Guard’s last contract also covered the design rights, which means a different shipyard could conceivably produce the Sentinel Class design. In 1880, Richard Etheridge became the first African-American to command a life-saving station. Having successfully cleared its Critical Design Review last month and the Department of Homeland Security’s Acquisition Review Board earlier in December, the Sentinel project is now approved to begin low-rate initial production (LRIP). In a long-delayed echo, the USCG recently took the time to award Peter Kennedy of the Orleans Historical Society its Meritorious Public Service Award, for restoring Webber’s CG36500 and turning it into a floating museum. The USCG has not disclosed how many companies responded to its Request for Proposals, but Rear Adm.
Coast Guard officials do not plan to update cost estimates for the FRC-B until after the contract is awarded. The Island Class extension program was just a small part of the Deepwater program constellation. The 110-foot Patrol Boat fleet has experienced 23 hull breaches (literally an opening in the hull from corrosion) requiring emergency dry docks.
Changes in the reconfigured craft included an extra 13 feet of length (to 123 feet), an 11-ton extension to their sterns, and a larger and slightly heavier upper works amidships. The $367.5 million dollar conversion program had been announced during February 2003 by Fred P. During sea trials with the lead ship in the summer of 2004, the USCGC Matagorda cracked amidships at [structural] Frame 22 while running at approximately 24 knots near Key West in Sea State 5 conditions (8-12-foot seas).

There must be some problem with my dimensioning, because, besides the problems with the slurry hulls (patches starting close to zero), to get them as far apart as shown in the screen an offset value of 50000 had to be inserted for the WW hull.

An attempt to extend the lives of their aged Island Class cutters ended as an expensive failure in 2005, and string of blunders has delayed replacements. DID discusses the programs, their outcomes and controversies, the fate of the Island Class and FRC-A programs, and the work underway to replace them.
That forced an end to the contractor-managed effort, and the subsequent breakup of the Deepwater Lead System Integrator model brought the next steps under the sole control of the US Coast Guard. They will be armed with a Mk38 MOD 2 stabilized, remotely-operated 25mm chain gun that can fire accurately from a pitching ship, and 4 crew-served .50-caliber machine guns. Other modifications from the original Damen design include stern launch facilities for a rigid hulled inflatable boat, an electrical system that offers North American voltages, and a reconfigured interior.
The design’s base endurance at sea with full crew is just 5 days, but they can sortie often, giving them the ability to be underway for 2,500 hours per year. It remains to be seen whether the 24 ships of the follow-on FRC Phase II buy will stay with the Damen design, or field a different design that meets FRC requirements.

The first 6 FRCs were delivered to Miami, FL, and the next 6 are being homeported at Key West, FL.
Bollinger Shipyards of Lockport, LA receives a 255.1 million contract option for 6 more Sentinel Class Fast Response Cutters (FRCs) and 3 sets of deep insurance spares.
Nine FRCs have been commissioned into service, and the Raymond Evans, will be commissioned this September in Key West, FL.
Coast Guard Cutter Kathleen Moore [WPC 1109] is commissioned into service at Coast Guard Sector Key West, FL, becoming the 3rd of 6 ships of class that will eventually be homeported there. The Coast Guard accepts delivery of Coast Guard Cutter Kathleen Moore [WPC 1109] in Key West, FL.
Coast Guard Cutter Charles Sexton [WPC 1108] is commissioned into service at Coast Guard Sector Key West, FL. The Coast Guard announces the names and backgrounds of Sentinel-Class Fast Response Cutters WPC 1116 – WPC 1125, along with brief explanations of each USCG hero behind a ship name.
Sexton boarded the sinking fishing vessel Sea King, and worked pumps for 6 continuous hours to keep her afloat.
The Coast Guard exercises a $250.7 million option with Bollinger Shipyards for 6 FRCs to be delivered in 2016. DHS approves the Sentinel-class FRC program for full rate production after it successfully completed its Initial Operational Test and Evaluation (IOT&E). After his boat came under attack by an enemy fighter, Clark assumed control of the boat, brought his wounded crewmembers to the destroyer USS Palmer, then returned the damaged boat to the beach to complete its mission.
SitNews reports that the USCG plans to build a 405-foot floating pier and a new 3,000 square foot support building in Ketchikan, AK, in order to homeport 2 FRCs there by 2015.
One had her rowing for 2 hours through a severe storm on Lake Pontchartrain in 1926, then heading back in with a downed naval aviator. CGC William Flores (WPC 1103), the 3rd FRC boat, is commissioned into service in Tampa, FL. Seaman apprentice William Ray Flores was 1 of 23 crew members who died in that accident, as he chose to stay aboard to help shipmates rather than abandon ship.
All 6 Sentinel Class boats are scheduled to be delivered in 2015, and homeported in San Juan, Puerto Rico.
CGC Cutter Richard Etheridge (WPC 1102), the 2nd FRC boat, arrives at Port Everglades, FL and is commissioned into service. If the Coast Guard exercises all options on the initial FRC-B contract with Bollinger, Phase II will be 24 ships.
They would begin from a disadvantage when compared to what Bollinger has learned by building that design to date, but a switch is not impossible. The US Coast Guard announces its decision to name all FRC Sentinel Class cutters after enlisted Coast Guard heroes, who distinguished themselves in USCG or military service. The entire FRC contract contains options for up to 34 cutters, and is worth up to $1.5 billion (vid. Webber, is approximately 70% complete, and is expected to be delivered to the Coast Guard in the spring 2011. A keel laying ceremony for the first FRC takes place at Bollinger Shipyards in Lockport, LA. US Coast Guard officials announce that the first Sentinel-class cutter will change its name from Sentinel to “Bernard C. Meanwhile, the 2 firms continue to cooperate as joint members of the team building Lockheed Martin’s Littoral Combat Ship design.
It will complete a comprehensive operational test and evaluation period, and then enter operational service in the Caribbean. The Coast Guard is currently evaluating proposals and expects to award the FRC-B contract in the third quarter of fiscal year 2008, with the lead cutter to be delivered in 2010.
Gary Blore forwards recommendations to Coast Guard senior leadership in a formal decision memorandum. The US Coast Guard takes the first legal steps to recoup up to $100 million from the contractors who oversaw the failed Island Class cutter modernization, via a revocation of acceptance letter. The modifications were intended to accommodate dual-gender quarters, a more robust communications suite, and a boat ramp on the stern. By March 2005, the converted cutters Nunivak and Padre also began experiencing problems with hull buckling. The alternations had changed the vessels’ center of gravity, and the vibration patterns throughout their hulls. All 8 ships were officially placed in limbo and taken out of service, more than 2 years after the first ship began buckling in heavy seas.
Coast Guard and ICGS successfully completed the preliminary design review for the 58 FRC vessels, giving the project their official go-ahead.

The Island Class’ safe lifetime is running out fast, but by the end of 2013 FRC Sentinel Class deliveries were set to ramp up to full production pace.
His report showed that out of 39 similar naval organizations surveyed, only 2 countries had fleets older than the United States Coast Guard. A positive GAO report on the overall program in June 2006 was followed by December 2006 revelations that stretched beyond the Island Class and Fast Response cutters. The ships will be powered by 2 TIER II diesel engines rated at 5,760 bhp, driving fixed rather than controllable-pitch propellers. Like their fellow Deepwater cutters, FRCs will carry a subset of the Deepwater C4ISR (command, control, communications, computer, intelligence, surveillance, and reconnaissance) system. Boats 13-18 are slated for San Juan, Puerto Rico, and boats 19-20 will be based in Pascagoula, MS.
It was one of the modernized Island Class cutters, and the FY15 budget provides for decommissioning 8 more Island Class boats. Nine more FRCs are currently in production at Bollinger Shipyards in Lockport, LA, out of 16 more ordered. This concludes a rather beefy LRIP phase of 12 ships out of the 34 total contracted in September 2008. A barge carrying several hundred tons of mortars had been hit by enemy rocket fire, and there were 15 Kilotons of explosives at risk, including 2 more ammunition ships nearby. He received the Coast Guard Medal as a posthumous honor, and now has a ship named after him.
The RFI also implies that different designs might be considered, however, which could open the competition to options like Westport’s GRC43. This 2nd Sentinel Class cutter will undergo a series of tests and evaluations prior to its planned delivery to the USCG early in 2012. Webber, enters the water after a 3-day journey from the fabrication shop, which included a tow across Highway 308.
The other 3 FRCs ordered to date are currently under construction: #2 is about 40% complete, #3 is 15% complete, and #4 is just 1% complete, at the moment. To honor past Guardians who stood the watch, each Sentinel-class FRC will be named for one of the Coast Guard’s many enlisted heroes.
On February 18, 1952, Petty Officer Webber led his 3-man crew through a fierce Cape Cod winter storm’s 60-foot waves, in order to save the lives of 32 crewmen from the SS Pendleton, a 504-foot freighter that had been split by onboard explosions. With the global price of steel skyrocketing, economic price adjustment contracts are important addenda to shipbuilding contracts these days.
By the end of 2005, the Coast Guard will have taken delivery of eight reconfigured 123-foot patrol boats, which are upgraded 110-foot patrol boats designed to sustain this cutter class until replacement with the Integrated Deepwater System’s Fast Response Cutter. That same month, similar hull deformations were discovered in 3 other modified boats: the Metompkin, Vashon, and Monhegan.
This created new levels of stress in areas of the ship that had not been built to take them, in a set of hulls that were already quite old and fatigued when the conversions were started.
By April 28, 2006, the GAO gave Deepwater a review that lauded improvements to the program.

The problem is keeping up numbers, after all of the delays and false starts chronicled in this FOCUS briefing. After boarding the ship, he helped stabilize an injured crew member and dewatered flooded compartments of the ship for 6 hours to keep it afloat.
Sexton and 2 of the fishing boat’s crew members lost their lives, and he was posthumously awarded the Coast Guard Medal for extraordinary heroism. The contract requires that 3 to 4 cutters be ordered each year; so far, 7 cutters have been delivered, and the 7th will be commissioned in November 2013.
In its August 2012 report [PDF], the DHG IG had noted that this was a rather aggressive acquisition plan which limited the Coast Guard’s ability to control risks. Indeed, the first 6 FRCs are scheduled to be stationed in Miami to support operations in the 7th Coast Guard District, an area ranging from the South Carolina coast to the Caribbean.
Pattie Hamilton, is the ship’s sponsor, and his granddaughters, Leah and Hilary, are the maids of honor. The approximate maximum value of this contract, if all options are exercised and all 34 patrol boats are ordered, is about $1.5 billion over 6-8 years.
The contract will include a 2-year base period for the design and production of the lead cutter and six 1-year option periods. This firm was intended as a joint venture sub-contractor to Northrop Grumman Ship Systems for the Deepwater program, and immediately pursued the contract to modify and lengthen the 49 Island Class vessels specified in the interim plan. As a result of the deteriorating hull conditions, the Coast Guard imposed operational restrictions on the boats in April 2005.
