Medium endurance cutter

The Medium Endurance Cutter or WMEC is a type of United States Coast Guard Cutter mainly consisting of the 270 ft Famous- and 210 ft Reliance-class cutters. These larger cutters are under control of Area Commands (Atlantic Area or Pacific Area). These cutters have adequate accommodations for crew to live on board and can do 6 to 8 week patrols. Other ships in the WMEC classification are the 282 ft USCGC Alex Haley (WMEC-39), and the now-decommissioned 213 ft USCGC Acushnet (WMEC-167), and 230 ft USCGC Storis (WMEC-38), and 205 ft USCGC Tamaroa (WMEC-166) which began as the United States Navy Cherokee-class fleet tug USS Zuni (ATF-95) launched in 1943.

There are 13 vessels in the Famous class, and 12 vessels still in active US service in the Reliance class. The Coast Guard plans to eventually phase out the vessels in both of these cutter classes and replace them with the Offshore Patrol Cutter as part of the Integrated Deepwater System Program.

History
After World War II, the United States Coast Guard used the US Navy hull classification system. The large, sea-going cutters were classified primarily as Coast Guard gunboats (WPG), destroyer escorts (WDE), and seaplane tenders (WAVP). In 1965 the Coast Guard adopted its own designation system and these large cutters were then referred to as Coast Guard High Endurance Cutters (WHEC). The coastal cutters once known as Cruising Cutters, Second Class and then as Coast Guard patrol craft (WPC) were now Coast Guard Medium Endurance Cutters (WMEC)."

Famous-class cutter
The Famous-class vessels have hull numbers in the range from WMEC-901 through WMEC-913. Entering service in the 1980s, the Famous-class cutters were designed as replacements for the 327 ft Treasury-class cutters, and their mission profile emphasized law enforcement, particularly patrolling the newly established 200 mi exclusive economic zone.

The Coast Guard harvested weapons systems components from decommissioned Oliver Hazard Perry-class frigates to save money. Harvesting components from four decommissioned frigates resulted in more than $24 million in cost savings, which increased with parts from more decommissioned frigates. Equipment such as the Mark 75, 76 mm/62 caliber gun mounts, gun control panels, barrels, launchers, junction boxes, and other components from decommissioned Oliver Hazard Perry-class frigates were returned to service aboard Famous-class cutters in order to extend their service lives into the 2030s.

Reliance-class cutter
The Reliance-class vessels have hull numbers in the range from WMEC-615 through WMEC-630. Entering service between 1964 and 1969, the Reliance-class cutters were meant to replace the 125 ft cutters of the Prohibition era and were the first major cutter replacement project since the 255 ft Owasco-class cutters from World War II.

The 210s (210-foot cutters) received upgrades and modifications (in a program named "Midlife Maintenance Availability" or MMA) during the 1986 through 1990 time period. The "A"-class cutters had their gas turbines removed, and all 210s had their stern transom exhaust systems replaced with a traditional stack. While this modification reduced the size of the flight deck, they were still more than capable of carrying out helicopter operations. Other modifications included enlarging the superstructure area, replacing the main armament, and increasing the fire-fighting capability of the cutters. The modifications cost approximately $20 million per cutter, well above their original cost of about $3.5 million each.

Ships in class
Courageous was decommissioned on 19 September 2001. She was transferred to the government of Sri Lanka on 24 June 2004 as SLNS Samudura (P-621).

Durable was decommissioned on 20 September 2001. In 2003 she was transferred to the Coast Guard of the Colombian Navy as ARC Valle del Cauca (PO-44).

Decisive was decommissioned on 2 March 2023.

Steadfast was decommissioned on 1 February 2024.

Dependable was removed from active service and placed in commission, special status on 9 April 2024. Her crew were transferred to other Coast Guard units to help meet the service-wide shortage of enlisted personnel.

Dauntless was removed from active service and placed in commission, special status on 21 June 2024. As of that date she had served 56 years. She and Steadfast are the only two Coast Guard cutters to have seized one million pounds of marijuana.
