The USCGC Munro (WHEC-724) was a high-endurance cutter commissioned by the United States Coast Guard on September 27, 1971, at Avondale Shipyard in New Orleans, Louisiana. As the tenth of twelve 378-foot (115 m) cutters, she was notable for being the first to be named after a Coast Guard hero—Signalman First Class Douglas A. Munro—whose service earned him the Medal of Honor. Originally, she had a complement of 17 officers and 143 enlisted personnel. Constructed at Avondale, the Munro featured the typical design of the Hamilton-class cutters, emphasizing endurance and multi-mission capability. Her initial homeport was Boston, Massachusetts, where her early missions focused on ocean station patrol and search and rescue operations. In 1973, she relocated to Seattle, Washington, shifting her focus toward fisheries enforcement, particularly targeting illegal foreign fishing vessels in Alaskan waters. Her law enforcement efforts included seizing vessels such as the Korean longliner Dong Won No. 51 in 1979. In 1980, Munro moved her homeport to Honolulu, Hawaii, and later, in 1989, she was homeported at Coast Guard Island in Alameda, California, following a major modernization that upgraded her weapons systems and internal components. Throughout her service, she conducted numerous notable law enforcement and rescue missions, including intercepting illegal vessels, seizing significant quantities of narcotics—such as 11.5 tons of cocaine in 1998—and participating in international operations like the relief efforts after the 2004 tsunami. Her most significant rescue operation was on March 23, 2008, when she rescued 20 survivors from the sinking FV Alaska Ranger, earning recognition as the largest cold-water rescue in Coast Guard history. After nearly five decades of active service, Munro was decommissioned on April 24, 2021, at Kodiak, Alaska. Subsequently, she was transferred to the Sri Lanka Navy on October 26, 2021, where she was commissioned as SLNS Vijayabahu (P627). She underwent extensive refits and arrived in Colombo in November 2022. As Vijayabahu, she continues to serve in regional maritime security, participating in multinational exercises and rescue missions, maintaining her legacy as a versatile and durable offshore patrol vessel.
