HNLMS Aldebaran was a Government Navy patrol boat. She would be militarized by the Royal Netherlands Navy upon the start of the Pacific theatre of World War II.

HNLMS Aldebaran was stationed at Makassar when war broke out. She would be transferred to Surabaya harbor where she would serve as an accommodation ship and guard ship due to stability issues that she had suffered from ever since commissioning.

After the fall of Java, she would be scuttled by her own crew on 2 March 1942 as it was not deemed possible to escape to Australia by that point.
