Design and construction

The keel was laid on 26 November 1938. The ship was launched on 16 March 1940 and the unfinished ship was evacuated to England after the German invasion of the Netherlands. She was completed in Great Britain, with six British 4-inch dual purpose guns instead of planned five 120 mm guns. The ship was modern for her time, she was fast and had two manually stabilized 40 mm Bofors AA-guns, each with its own "Hazemeyer" fire control, an on-mount mechanical analog fire control computer integrated with a on-mount optical rangefinder. It was the first Dutch ship to use radar to aim its AA-guns. The ship's plans were saved from the Germans and elements were incorporated into Royal Navy ship designs. [1]

Isaac Sweers was part of the Allied flotilla of destroyers which torpedoed and sank the Italian cruisers Alberico da Barbiano and Alberto di Giussano on 13 December 1941, at the Battle of Cape Bon. She riddled Alberto di Giussano with gunfire at short range and launched four torpedoes against the Italian torpedo boat Cigno; all of them missed their target. She escorted the important convoy MW 8B to Malta in January 1942. During this mission the British destroyer Gurkha was torpedoed by the German submarine U-133 on 12 January 1942. Isaac Sweers towed the stricken British destroyer through a field of burning oil and saved her entire crew of 240 sailors. They were taken to Tobruk.

[2] On 13 November 1942, Isaac Sweers was hit by two torpedoes from the German submarine U-431 under command of Wilhelm Dommes. She sank with the loss of 108 of her 194 crew.
