SLNS Gajabahu (P626)
SLNS "Gajabahu" (P626) () is an Advanced Offshore Patrol Vessel of the Sri Lanka Navy. The ship is the second ship named after King Gajabahu I, the warrior king of the medieval Sri Lankan Kingdom of Anuradhapura. Formerly, it was USCGC "Sherman" (WHEC-720) a United States Coast Guard Hamilton-class high endurance cutter named for John Sherman, the 32nd United States Secretary of the Treasury and author of the Sherman Antitrust Act. United States Coast Guard. CGC "Sherman"s keel was laid on January 25, 1967 at Avondale Shipyards in New Orleans, Louisiana. She was launched on September 3 , 1968. CGC "Sherman" was originally homeported in Boston, Massachusetts where her primary mission was ocean station patrol in the North Atlantic. In 1970, "Sherman" was assigned to Coast Guard Squadron Three in Vietnam. Her tasking during the conflict was primarily in support of Operation Market Time, which involved sorting through hundreds of small vessels off the Vietnamese coast in search of enemy weapons smugglers. "Sherman"s crew inspected some 900 vessels during her 10-month tour in Southeast Asia. The old 5" gun (now replaced by a 76mm mount) answered 152 calls for naval gunfire support, including a running fight  on the night of 21 November 1970 which resulted in sinking the North Vietnamese armed freighter "SL-3", which was carrying tons of enemy munitions. In 1971, "Sherman" returned to Boston. With satellite technology reducing the need for ocean station patrols and amid concern of the rising American drug problem, the emphasis shifted to drug interdiction. In October 1976, "Sherman" seized the 275-foot Panamanian freighter "Don Emilio" and confiscated 82 tons of marijuana, the largest drug seizure in history at the time. Responding to a need for greater operational resources in the Pacific, "Sherman" was transferred to her next homeport  in Alameda, California in May 1979. "Sherman"s primary missions shifted to Alaskan Patrols (ALPAT) involving fisheries law enforcement (LE), drug interdiction, search and rescue (SAR), and military readiness in the Bering Sea and Gulf of Alaska. "Sherman" was decommissioned from May 1986 until July 1989 to complete a three-year Fleet Renovation and Modernization (FRAM) project at Todd Shipyard in Seattle, Washington. The project upgraded "Sherman"s weapons, communications, aviation and other operating systems and completely renovated crew living and berthing spaces. "Sherman" completed ready-for-sea trials in July 1990 and once again commenced operational missions in the Pacific. In  July 2001, "Sherman" became the first Coast Guard cutter to circumnavigate the world, after conducting U.N. sanctions enforcement duty in the Persian Gulf and goodwill projects in Madagascar, South Africa, and Cape Verde. "Sherman" was involved in search and rescue efforts following the sinking of F/V "Big Valley" near Saint Paul Island, Alaska, on January 15, 2005. CGC "Sherman" appeared in the 2005 film "Yours Mine & Ours". In May 2006, the cutter participated with a U.S. Navy task group during a five-month deployment to Singapore, Thailand, Indonesia, Malaysia, Brunei and the Philippines. In March 2007, "Sherman" received worldwide  attention when her boarding team discovered more than 17 metric tons of cocaine aboard the Panamanian freighter "Gatun", a record seizure in the Eastern Pacific. "Sherman" was awarded the Golden Eagle award by the White House for combined interdiction successes during 2007. In May 2011, "Sherman" was transferred to San Diego, California. "Sherman" continued her operations by accomplishing three drug interdiction deployments in the Eastern Pacific, a winter Alaskan patrol in the Bering Sea to enforce U.S. fisheries regulations and to provide search-and-rescue support during the Alaskan red king crab harvest, and by earning the Pacific Area Operational  Readiness Award. In May 2015, "Sherman" transferred her homeport to Honolulu, Hawaii. After a final patrol in the Bering Sea, "Sherman" returned to Honolulu on January 23, 2018 to await decommissioning on March 29, 2018. Two new National Security Cutters will replace "Sherman" and the previously-retired in Honolulu. Sri Lanka Navy. On 27 August 2018, at Honolulu, the ex-"Sherman" was transferred to the Sri Lanka Navy. Ex-"Sherman" was recommissioned 6 June 2019 as SLNS "Gajabahu" (P626). The ship is the second ship named after King Gajabahu I, the warrior king of the medieval Sri Lankan Kingdom of Anuradhapura. The  ship retained its Otobreda 76 mm gun and MK 92 Fire Control System, while the Phalanx CIWS was removed and was replaced with a rear dual 23mm cannon.
