126 Feet-class minesweepers

The 126-feet minesweepers were an enlarged version of the 105-feet-class. They were intended to be more seaworthy and had better accommodation for the crew. They were capable of sweeping acoustic mines using their SA-gear and magnetic mines using their LL-sweep. In May 1945, these ships were fitted with captured German gear against anchor mines. The Dutch Navy acquired 8, and named them after Dutch islands.

After commissioning, these ships became part of teh 203rd Minesweeper Flotilla. Divisions were stationed at Yarmouth and Harwich. As the allied armies advanced across Europe's mainland, former German-occupied ports had to be cleared of mines before convoys could enter. In September 1944, the flotilla was active off Oostende (Belgium). Starting May 1945, these ships were active in clearing the North sea off the Dutch coast. In October 1945, the flotilla left with the Jan van Brakel for the Netherlands East Indies, where they arrived in January, 1946. With intervals, these ships continued operations until 1950, with the Walcheren as their only loss. The remainder were either transferred to the newly-established Indonesian Navy or continued operations off New Guinea.

* More recent information shows that Duiveland was ex-MMS 1074 rather than MMS 1044, as reported in Dutch sources and H.T. Lenton "Navies of the Second World War II: the Royal Netherlands Navy". The source for this new info is M.J. Melvin "'Minesweeper, the Role of the Motor Minesweeper' in World War II" and H.T. Lenton's own "British and Empire Warships".
** Dutch sources often mention Richard Crowns Iron Works as the builder.
