HNLMS Kortenaer () was an of the Royal Netherlands Navy, named after 17th century Dutch Admiral Egbert Bartholomeusz Kortenaer. Design In the mid-1920s, the Netherlands placed orders for four new destroyers to be deployed to the East Indies. They were built in Dutch shipyards to a design by the British Yarrow Shipbuilders, which was based on the destroyer , which Yarrow had designed and built for the British Royal Navy. The ship's main gun armament was four guns built by the Swedish company Bofors, mounted two forward and two aft, with two anti-aircraft guns mounted amidships. Four 12.7 mm machine guns provided close-in anti-aircraft defence. The ship's torpedo armament comprised six torpedo tubes in two triple mounts, while 24 mines could also be carried. To aid search operations, the ship carried a Fokker C.VII-W floatplane on a platform over the aft torpedo tubes, which was lowered to the sea by a crane for flight operations. Service history The ship was laid down on 24 August 1925, at the Burgerhout's Scheepswerf en Machinefabriek, in Rotterdam, and launched on 30 June 1927. The ship was commissioned on 3 September 1928. On 11 June 1929, a detachment of marines was sent on Kortenaer to Curaçao, after Venezuelan rebels, led by Rafael Simón Urbina, had raided Fort Amsterdam, in Willemstad, on 8 June. World War II In 1940, she and her sister guarded five German cargo ships. The ships were relieved by the cruiser on 26 April 1940. She served mostly in the Netherlands East Indies, and when war broke out in 1941, she was at Surabaya. She took part in Battle of Badung Strait on 18–20 February 1942, where she ran aground on one of the channel shores after temporarily losing rudder control. It was impossible for the Dutch ship to return to the formation, and they had to wait for the next morning tide to free the ship. Kortenaer was sent to Surabaya for repairs. She was back in action in time for the Battle of the Java Sea on 27 February 1942, where she was torpedoed at 17:14 by the Japanese cruiser . The commanding officer, Alexander Sharp, of the nearby United States Navy destroyer, , recorded that, "Kortenaer, about bearing 80° relative, was struck on the starboard quarter by a torpedo, blew up, turned over, and sank at once leaving only a jackknifed bow and stern a few feet above
