The '''''Jan van Amstel'' class''' was a [[ship class|class]] of nine [[minesweeper]]s 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 [[World War II|Second World War]], three of the four ships that were still under construction were never completed.

==Description==
The ''Jan van Amstel''-class ships were {{convert|55.8|m|ftin}} long, with a [[Beam (nautical)|beam]] of {{convert|7.8|m|ftin}} and a [[Draft (ship)|draught]] of {{convert|2.2|m|ftin}} at [[deep load]]. They [[Displacement (ship)|displaced]] was {{convert|450|LT|t|lk=on}} at normal load, which increased to {{convert|585|LT|t}} at deep load. A pair of [[Yarrow boiler]]s fed steam to two [[Marine steam engine#Triple or multiple expansion|triple-expansion steam engines]] that each drove a single [[Propeller (ship)|propeller shaft]]. The engines were rated at {{convert|1690|ihp|kW|lk=on}} which gave the ships a speed of {{convert|15|kn}}. They carried up to {{convert|110|LT}} of [[fuel oil]] and had a [[Ship's company|complement]] of 45 officers and [[Naval rating|ratings]].<ref>Roberts, p. 394; van Willigenburg, p. 106</ref>

The ships could also be used as [[minelayer]]s. The construction of the ships took place in two different [[shipyard]]s, four by Gusto, [[Schiedam]] and five by P. Smit, [[Rotterdam]].
