Dutch joint support ship Zr.Ms. Karel Doorman. Het Sloe, Vlissingen 4 July 2014

In the 19th meeting of the Tweede Kamer of the Dutch parliament on 7 December 1965 was the request of the Royal Netherlands Navy for a helicopter carrier in the budget for 1966 discussed. Parliament member Bos (of the C.H.U.) asked if such a ship was a satisfying alternative instead of having nuclear submarines. One advantage was that the Netherlands became less depending on other countries. Whatever the answer was from the minister there were no helicopter carriers built. Both ships were planned to be built between 1971-1977 respectively 1972-1978. Dimensions 182 (between perpendiculars)-190 (over all) 23 (waterline)-27 (flight deck) x 7,5 (maximum draught) x 18 (hold below flight deck) metres and a maximum displacement of 18.000 tons. Hangar storage for 9 helicopters and 8 helicopters could depart at the same time. Speed 24 knots with a horsepower of around 50.000hp. Armament consisted of 2 PDMS or Point Defence Missile System (3-4 launchers) at the foreside of the ship. Accommodation for a crew numbering about 600 men and furthermore for around 320 marines. Could take 2.000 tons of fuel oil for supplying purposes at sea. Could carry at least LCA’s with her. Main tasks of the helicopter carriers war anti submarine warfare and such a ship needed a protection of at least 4-6 destroyers or frigates. Such a squadron needed an endurance of at least 14 days without returning to a base for victuals. At that moment was the Dutch light aircraft carrier Hr.Ms. Karel Doorman just sold.(1)
