Jan van Amstel-class minesweeper

The Jan van Amstel-class was a class of nine minesweepers of the Royal Netherlands Navy, built to serve in the Dutch East Indies and Dutch territorial waters in Europe.

The class was originally planned to consist of 12 ships, but because of the German occupation of the Netherlands in the Second World War, three of the four ships that were still under construction were never completed.

The ships could also be used as minelayers. The construction of the ships took place in two different shipyards, four by Gusto, Schiedam and five by P. Smit, Rotterdam.
