The United States Coast Guard’s Sentinel-class fast response cutters (FRCs) have emerged as a significant force for international deployments, dwarfing the legacy Island-class patrol boats in size, sensors, weaponry, and range. With 52 FRCs operational as of December 2022 and 13 in construction, the Coast Guard’s FRCs not only represent a radical upgrade but also offer the Navy an opportunity to utilize these cutters as future missile patrol vessels in support of distributed maritime operations.
The FRC, more tonnage and advanced than its predecessors, has already demonstrated its capability through multiple expeditionary deployments. Since being commissioned in April 2012 by the first of class FRC, the Bernard C. Webber (WPC-1101), these cutters have conducted counterdrug operations interdicting thousands of pounds of narcotics, supported international partnerships, and participated in multinational exercises from the Pacific to the Arctic.
With the Coast Guard continuing to prove out the FRC’s capabilities, the Navy is growing more interested in applying this platform to its missile patrol boat fleet. The FRC design lays out a high-speed, stable platform with excellent endurance that is very well-suited for conversion to a missile craft mission. Equipped with gyro-stabilized Mk 38 Mod 2 25-mm autocannon, .50-caliber machine gun, and state-of-the-art sensor and communications packages, the FRCs have already demonstrated flexibility in weaponry and technological integration.
The deployment of the FRCs to Bahrain during 2020 further reflects their growing maritime security role. Although they have been successful in replacing the Navy’s Cyclone-class patrol boats, operational commanders have been able to deploy these cutters for as long as 40 days at a time in the northern Arabian Sea, interfering with illegal arms and narcotics. This demonstrates the FRC capability for long-endurance patrols and its capacity to be outfitted with other weapons systems, such as the Naval Strike Missile, without reducing its core missions.
Although they possess many strengths, extended FRC deployments do have inherent risks and logistical challenges, including crew fatigue, medical resource limitations, and demands for innovative solutions to the storage of food and fuel. To reduce such challenges, the Coast Guard has attempted to make FRC operations sustainable by applying changes to work-to-rest ratios and utilizing support teams during port calls.
The FRC’s consideration by the Navy to be a missile patrol boat is not new. The previous deployment of anti-ship missiles on Coast Guard cutters during Admiral Paul A. Yost’s tenure indicates that there have been times in the past when cutters were equipped for more naval combat capability. The current geopolitical situation and technological developments revive discussion of arming cutters with missiles. The FRC, with its hot manufacturing line and affordability reputation, is a natural fit for the Navy’s shift to distributed maritime operations.
