The DEFG class was a class of ten minesweepers. Officially classed as auxiliary minesweepers, these ships made up the bulk of the Dutch minesweeper capabilities in the Dutch East Indies. Derived from the preceding ABC class, they were constructed with future Government Navy usage in mind where they would most likely be used as patrol boats and small personnel and cargo transports.[1][2][3]
