As a result of the Korean war experience
the United States undertook the construction of a new series of minesweepers on
a large scale. During the decade of the 1950s sixty-five new minesweepers were
built. These new minesweepers were designated Minesweeper, Ocean (non-magnetic (MSO).
They consisted of three classes of ships: Agile/Aggressive, Hull numbers 421 to
507; Acme, hull numbers 508 to 518; and Ability, hull numbers 519 to 522. In
contrast to the steel-hulled minesweepers of World War II, designated (AM) later
(MSF) and still later (MSO(O), these new minesweepers were smaller and built
primarily of wood , with bronze and stainless (non-magnetic) steel fittings to
minimize their magnetic signature. All of the 1950 era MSOs had UQS-1
mine-locating sonar, later updated with SQQ-14 sonar. MSOs were capable of
sweeping for moored and bottom contact, magnetic and acoustic mines.
Hr.ms.Mercuur is the only remaining Ocean Minesweeper of the U.S Navy in the Netherlands after the second Wold War,together with five sister ships, the Ocean Mine Sweeper assisted in the clean up of sea mines in the important waterways to the Dutch harbours.
These ships played a role in the rebuilding of the economy of the Netherlands
