Medium endurance cutter

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==

Entering service in the 1980s, the Famous-class cutters were designed as replacements for the s, and their mission profile emphasized law enforcement, particularly patrolling the newly established exclusive economic zone. Ships in class . Service life extension program The service life extension program (SLEP) for eight cutters of the class started in July 2021 with prototype work for electrical and structural systems on the Seneca and Harriet Lane. Additionally, Harriet Lane served as the prototype for the replacement of the main gun with a Mk38 Mod 3 25mm machine gun. The production phase of the SLEP, which will be carried out on Spencer, Legare, Campbell, Forward, Escanaba and Tahoma, covers four main areas: the electrical, structural and weapons systems work prototyped on Seneca and Harriet Lane and finally replacement of the main propulsion Diesel engines. The last SLEP is expected to be complete by 2030. == Reliance-class cutter ==

Entering service between 1964 and 1969, the Reliance-class cutters were meant to replace the cutters of the Prohibition era and were the first major cutter replacement project since the s from World War II. USCGC Courageous (WMEC 622) was decommissioned on 19 September 2001. She was transferred to the government of Sri Lanka on 24 June 2004 as (P-621). USCGC Steadfast (WMEC-623) was decommissioned on 1 February 2024 and transferred to the Malaysian Maritime Enforcement Agency. USCGC Dauntless (WMEC-624) 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. USCGC Dependable (WMEC-626) 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. USCGC Durable (WMEC-628) 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). USCGC Decisive (WMEC-629) was decommissioned on 2 March 2023. ==Notes==
