The Onversaagd class was a ship class of six minesweepers that were built in the United States for the Royal Netherlands Navy (RNN). They were paid for by the United States under the Mutual Defense Assistance Program (MDAP). The minesweepers were based on the design of the Aggressive class and taken into service of the RNN between 1954 and 1955.
