The K2 was a K-class sloop built for the Royal Netherlands Navy to replace the aging Brinio-class gunboats. Originally seven ships were planned, but only three were laid down and two more ordered. By the time of the German invasion of the Netherlands, the ships were still incomplete and not yet launched. The K2 was laid down in 1939 and commissioned in 1942. Very little is known about her career except that she was hit by an aerial torpedo on 9th October 1944, heavily damaging her. She was towed to port and at the end of the war found in port of Horten, Norway. She was then towed to the Dutch port of Delfzijl where she sank by accident in November 1945. On 26th July 1946, she was raised and, after inspecting her, sold for scrap in 1947.

The K2 was introduced in Update 1.79 "Project X" as part of the fleet closed beta test. Unlike any destroyer or even some light cruisers, the K2 features 40 mm thick belt armour protecting magazines with 50 mm plates protecting vital machinery such as engine and fuel tanks. The turret ammo elevators are surrounded by 60 mm armour as well as the turret itself are protected by 60 mm thick armour all-round making them immune to auto cannon and lower calibre fire. The bridge is protected by 35 mm rolled homogeneous armour all around, again making it much more protected than any of its contemporaries. As the K2 was designed to serve in coastal waters, her max speed is only 34 km/h. The main armament of four 120 mm cannons is on par with destroyers of other navies.
