The Holland-class destroyers were built for the Royal Netherlands Navy in the 1950s. They were the first major ships designed and built by the Dutch after World War II. In contrast to previous Dutch Navy practice the ships were named after provinces rather than admirals.
These ships were unusual as they were the first destroyers built without large calibre anti-ship torpedoes. Their primary role was anti-submarine warfare and convoy defence. The specification was issued in 1947 and construction was approved in 1948.
The armament comprised two twin Bofors 120 mm guns which were capable of 45 rounds per minute. The mountings were automated and stabilised with radar control and 720 rounds were stored per mounting. Initially British 4.5 inch twin Mk 6 mountings were considered but rejected due to complexity, man power requirements (19 men per mounting) and dependence on hydraulics for operation. The close range anti aircraft armament was reduced to a single Bofors 40 mm gun due to the heavy top weight of the 120 mm mountings. Anti-submarine weaponry consisted of two quadruple Bofors 357mm anti-submarine mortars sited in B position forward of the bridge.
The turbine machinery was ordered before the war for the Gerard Callenburgh-class destroyers and hidden during the German occupation. The turbines were built by Werkspoor and four boilers were used. The ships had a unit machinery layout with alternating boiler rooms and turbine rooms.
The radars were designed by Hollandse Signaal Apparaten; The ZW-01 provided surface warning, the DA-01 provided medium range surveillance and the LW-02 long range surveillance. Fire control was provided by the GA-03 and KA-01 radars. Sonars PAE-1N and \\cwe-10 were also fitted.
The superstructure was built of aluminium alloy in order to reduce weight and electric welding was used throughout.
The Netherlands navy considered replacing the after 120 mm turret with a guided missile system in the late 1950's but this project was cancelled.
