SLNS Samudura (P-621) (Samudura, in Sinhalese: Sea) is an Offshore Patrol Vessel (OPV) of the Sri Lanka Navy. Formerly the USCGC Courageous of the United States Coast Guard, the medium endurance cutter was donated to Sri Lanka on June 24, 2004.


Samudura is tasked with deep sea patrolling both within the Sri Lankan territorial waters and in international waters to curb ongoing arms smuggling by the LTTE. In recent months Samudura, along with other OPVs of the Sri Lankan Navy, has been able to successfully intercept several ships smuggling arms for the LTTE. In all these cases the ships were sunk when they attacked the naval vessels with mortars. Samudura also participated in the Cadex 2009 military training exercises with the Indian Navy after the war.[1]

SLNS Samudura in her post-conflict operations continue to serve the nation with policing and law enforcement duties in maritime jurisdiction of the country. Apart from her traditional role the ship successfully completed a scientific study programme in liaison with Geological & Mine Bureau of Sri Lanka in conjunction with Woods-hole Oceanographic Laboratory of USA. The ship celebrated her 7th anniversary in Trincomalee on 21 April 2012 with the participation of families of all her serving crew. Furthermore, the ship performed a major role in protecting the Sri Lankan waters from Indian poaching menace in the northern waters by enforcing strict vigil on the preservation of marine environment & supporting sustainable fish-harvesting. At present the ship is attached to the Southern Naval Area to secure maritime interests in Sri Lankan maritime jurisdiction. Her primary duties are to ensure the main Sea Lane of Communication (SLOC) that runs through the Sri Lankan maritime jurisdiction is safe for seafaring and policing the EEZ. Furthermore the ship has intercepted several boat loads of illegal immigrants heading to Australia violating the country's immigration & emigration laws.
