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.[2] They were known as RP104, RP105 & RP106.

In 1949 the ships were reclassified as shallow-water minesweepers, with their hull numbers changing to MV31, MV32 & 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) & HNLMS Zijpe (M883).

In January 1956 they left service as minesweepers and entered a refit period to become diving support vessels.[4] When the entered service as diving support vessels, there hull numbers changed once more to Y8128, Y8129 & Y8130 respectfully.[3]

Mastgat was and Zijpe were both decommissioned in 1962.[4] Keeten was the last to be decommissioned in 1964.[2]
