The K-class gunboats were ordered as a replacement to the outdated Dutch Brinio-class gunboats that preceded them. Originally, seven ships of the class were planned to be constructed, three of which were ordered and laid down right away. However, the German occupation of the Netherlands in 1940 abruptly ended the construction of the already laid down ships, with pending orders for the remaining ships getting cancelled. Following the occupation, all three uncompleted warships were captured after falling into German hands.

The Kriegsmarine decided to continue construction and to complete all three of the captured warships for use in the German war effort. Thus, the K-1, K-2 and K-3 were all subsequently completed by 1940/41 and were put into commision with the German navy by 1942. The three gunboats primarily saw service in Norwegian and German waters, performing patrols and other low-profile missions. K-1, the lead ship of the class, was sunk right at the end of WW2 in 1945 off the coast of Denmark. The К-2’s back of the deck was damaged by a torpedo during another air attack of the allies. The vessel had been towed back to Germany but was never repaired till the end of the war. After the war she was towed to the Netherlands where it sunk for unknown reasons, it was raised from the seabed and scrapped in 1946.K-3 was the sole survivor of the class, being recommissioned into Dutch service after WW2 under the name “Van Speijk”. K-3 remained in Dutch service until 1960, after which she was sold for scrap.
