Reliability for Norway, Readiness for NATO
KV Harstad (W 318) is one of the Norwegian Coast Guard’s most capable offshore patrol vessels, operating throughout Norway’s vast maritime areas including the Norwegian Sea, the Barents Sea and the fisheries protection zone around Svalbard.
Built at Søviknes Verft in 2005 and initially leased from Remøy Shipping, the vessel was taken over by the Norwegian Armed Forces in 2009 and has since served as a core asset within the Outer Coast Guard.
Key Facts
Reliability for Extended Deployment
KV Harstad is powered by two Bergen B32:40L8 engines, forming the vessel’s main propulsion system. These medium-speed engines provide the dependable performance required for long patrols, heavy-weather towing and slow-speed manoeuvring during sensitive Coast Guard tasks.
Their stable load response and long service intervals support the vessel’s varied operational profile, allowing KV Harstad to operate far from support hubs as needed.
Supporting NATO’s Submarine Rescue System
KV Harstad also plays an important multinational role as Norway’s dedicated platform for NATO’s Submarine Rescue System (NSRS). The vessel was lengthened during design to accommodate the equipment required for NSRS operations, enabling her to support rapid mobilisation in the event of a distressed submarine.
This capability strengthens Norway’s contribution to NATO’s collective readiness and ensures the alliance can respond quickly and effectively to underwater emergencies across the region. Modern aerial and underwater drones further expand the ship’s situational awareness during these high-priority missions.
