 To save costs and especially time, as the navy was in dire need of modern ships to replace some of its pre-war material, the four destroyers were provided with equipment that was built during the Second World War for the German Navy.In addition to these four submarine destroyers, two more other destroyers were planned to be built, but due to cost savings, the construction of these ships was postponed.Nonetheless, on 30 December 1954, the first "Holland"-class destroyer, "Holland", was completed and taken into active service.
