The Onversaagd class was a ship class of six minesweepers that were built in the United States for the Royal Netherlands Navy (RNN).[1] [2] They were paid for by the United States under the Mutual Defense Assistance Program (MDAP).[3] The minesweepers were based on the design of the and taken into service of the RNN between 1954 and 1955.[4]
To sweep naval mines the minesweepers of the Onversaagd class were equipped with the Wire Mk1, M Mk 6 A, A Mk 6B and the A Mk 4v. Furthermore, the ships had a single 40 mm gun. In addition, the minesweepers were equipped with a prototype of the UQS-1, but this mine avoidance sonar did not meet expectations.
While the Onversaagd-class minesweepers had a range of 2200nmi, it was deemed insufficient, as it meant that the ships could only stay at sea for a maximum of eight to nine days without having to replenish its oil.[5]
