The minimum demanded specifications for Dutch destroyers serving in the Dutch East Indies according to the Dutch magazine Marineblad dated 1925 no. 2

Hr. Ms. Wolf of the Roofdier-class

Hr.Ms. Kortenaer of the Admiralen-class

An item referred to a essay written by the Dutch lieutenant 2nd class J.A. de Gelder (1) on board of Hr. Ms. Vos (2) at Surabaya, Dutch East Indies on 10 December 1924 dealing with the issue what kind of destroyer the Royal Netherlands Navy needed for service in the Dutch East Indies. Their tasks were numerous from neutrality maintenance, scouting, anti aircraft defence, cruising-guarding-communication tasks, escorting own transports and so against the attacks of submarines of the enemy, battles with or without cooperating with cruisers and submarines, torpedo attacks at daytime against transport fleets and attacks in the nights against transports and warships. He compared figures supplied by Jane’s Fighting Ships of American, British and Japanese destroyers. His conclusion was an oil fuelled destroyer with a displacement of 1.500 ton with a range as large as maximum with the economic speed and a bunker capacity making a stay of some weeks at sea with a varying speed between economic-maximum possible. The maximum speed while full loaded was at last to be 32-34 miles. Except for the need of strong search lights was an armament of at least 3 but preferable of 4 12cm quick firing guns with complete central firing control, some light anti aircraft guns like 5cm twins or heavy machine guns and twin, triple of quad torpedo launchers for long distance torpedoes.(3)
