[5] In March 2007, newly appointed United States Coast Guard Commandant Thad Allen announced that the USCG had withdrawn a contract from Lockheed Martin and Northrop Grumman for the construction of an initial flawed design of what would eventually become the Sentinel class.

The 18th fast response cutter, Joseph Tezanos, was delivered to the Coast Guard in Key West, Florida, in June 2016 en route to completing the San Juan cohort.

[26] 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.

[28][29] In June 2019, the United States House Committee on Armed Services approved a requirement for the US Navy to study the possibility of buying a version of the FRC, and basing them in Bahrain.

[30] In 2019 Lieutenant Commander Collin Fox (USN), and columnist David Axe suggested that, when the US Navy started to develop unmanned patrol ships to replace the Cyclone class, which are similar in size to the Sentinel class, the hulls and other elements of the robot ships would be based on the Sentinels, and built in the same factory.

[34] In 2022, the Coast Guard awarded a $30 million contract to install a fixed pier and two floating docks to accommodate FRCs at East Tongue Point in Oregon.

[35] In March 2022, President Joe Biden signed the Consolidated Appropriations Act for Fiscal Year 2022, which provided $130 million in funding for two additional FRCs, bringing the total number to 66.

[43] 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.

[48] The bridge is equipped with a handheld device that allows crew members to remotely control the ship's functions, including rudder movement and docking.

[49] In February 2013, the Department of Homeland Security requested tenders from third party firms to independently inspect the cutters, during their construction, and their performance trials.

[50] At the September 2022 commissioning of USCGC Douglas Denman, it was announced that she had several upgrades compared to the two cutters deployed to Ketchikan, Alaska six years previously.

[52] In March 2024, a Congressional Research Service report revealed that the Coast Guard's long term procurement plan called for the purchase of up to 71 FRCs.

[53] Prior to the deployment of the Marine Protector class, the Coast Guard decided that all its cutters, even its smallest, should be able to accommodate mixed-gender crews.

When USCGC Rollin Fritch was commissioned, a profile in The Philadelphia Inquirer asserted off-duty crew members had access to satellite television broadcasts.

[182][183] Similarly, Charles Sexton helped search for the freighter El Faro when she was lost at sea during Hurricane Joaquin in October 2015.

[184] In 2018 and 2019 Oliver Berry and Joseph Gerczak made voyages beyond the design range, on missions from Hawaii to the Marshall Islands and American Samoa.

In August 2022, one of the ships in the Sentinel class, Oliver Henry, was stuck in the Solomon Islands after the country's government failed to respond to a fuel request.
