The Keeten class was a ship class of three minesweepers that served in the Royal Netherlands Navy (RNN) between 1946 and 1964. They were former Royal Navy harbour defence motor launches sold to the RNN in 1946.

History

The ships were used as patrol boats in the Dutch East Indies and in this role were equipped with a single 20 mm gun and a single machine gun. They were known as RP104, RP105 and RP106.

In 1949 the ships were reclassified as shallow-water minesweepers, with their hull numbers changing to MV31, MV32 and MV33 respectfully.

The three ships were decommissioned on 15 August 1951 and put on transport to The Netherlands on 2 September 1951. In February 1953 they were recommissioned as HNLMS Keeten (M881), HNLMS Mastgat (M882) and HNLMS Zijpe (M883).

In January 1956 they left service as minesweepers and entered a refit period to become diving support vessels. When the entered service as diving support vessels, there hull numbers changed once more to Y8128, Y8129 and Y8130 respectfully.

Mastgat was and Zijpe were both decommissioned in 1962. Keeten was the last to be decommissioned in 1964.
