HNLMS Abraham Crijnssen (1936)

On arriving in Australia in 1942, she was commissioned into the Royal Australian Navy (RAN) as HMAS Abraham Crijnssen and operated as an anti-submarine escort.

After the war, Abraham Crijnssen operated on anti-revolution patrols in the East Indies, before returning to the Netherlands and being converted into a boom defence ship in 1956.

[3][4] Built by Werf Gusto at their yard in Schiedam, South Holland, the minesweeper was launched on 22 September 1936, and commissioned into the RNN on 26 May 1937.

[3] The minesweepers were fitted with two Yarrow 3-drum boilers and two Stork[citation needed] triple expansion engines, which provided 1,690 ihp (1,260 kW) to two propeller shafts, allowing the ship to reach 15 knots (28 km/h; 17 mph).

[7] To escape detection by Japanese aircraft (which the minesweeper did not have the armament to defend effectively against), the ship was heavily camouflaged with jungle foliage, giving the impression of a small island.

[4][6][7] She headed for Fremantle, Western Australia, where she arrived on 20 March 1942; Abraham Crijnssen was the last vessel to successfully escape Java, and the only ship of her class in the region to survive.

[4] The wardroom tradition of hanging a portrait of the commissioned ship's reigning monarch led to some tension before it was decided to leave Queen Wilhelmina of the Netherlands on the bulkhead instead of replacing her with King George VI of the United Kingdom, which was installed in the lieutenant's cabin.

[5][8] Abraham Crijnssen was used for mine-clearing sweeps of Kupang Harbour prior to the arrival of a RAN force to accept the Japanese surrender of Timor.

[5] After leaving service, Abraham Crijnssen was donated to the Sea Cadet Corps (Zeekadetkorps Nederland) for training purposes.
