The US Navy received an Australian government contract to provide Naval mines for the protection of Australian ports and to disrupt Japanese shipping. As such the Navy built a Naval mine depot at the port of Darwin, in Darwin Harbour. Due to Japan's southern advance in the Pacific War into the Southwest Pacific the US Navy also built a submarine base and PT boat Bases on the northwest coast of Australia, to patrol and protect the shipping lanes. The city of Darwin is on a peninsula between Clarence Strait and Frances Bay in the northern coast of Australia. Naval Base Darwin was part of the 1942 American-British-Dutch-Australian Command (ABDACOM). With ABDACOM the Allies tried to limit the advance of Japan. ABDACOM did not have enough troops or supplies to carry out the mission in 1942.[3][4]
The submarine started with the arrival of the submarine tender USS Otus (ARG-20) worked at the base from December 10, 1941 to January 1942.[5] The submarine tender USS Holland (AS3) arrived on January 2, 1942 and began around the clock service to US submarines. A land submarine repair base with docks and depots was built to support the operations. In February 1943 Holland departed Australia for Mare Island Navy Yard for overhaul.[6] The USS Coucal (ASR-8) worked at the base from August 12, 1943 to October 29, 1944. USS Chanticleer (ASR-7) worked at the base from October 1944 to January 1945.[7]
The USS Black Hawk (AD-9) a destroyer tender operated out of Naval Base Darwin from January 3 to February 1942.[8] USS Langley (CV-1), the US Navy's first aircraft carrier, assisted the Royal Australian Air Force in running anti-submarine patrols out of Darwin from January 1 to 11 1942.
Much of the Darwin submarine base operations was moved to the Fremantle submarine base in Western Australia, as this was out of range of land-based Japanese aircraft. Darwin also had a high tide problem.[9]
In January 1945 US Navy Seabees built a Seabees base camp at Darwin. The other large US Naval Advance Bases in Australia were at Naval Base Brisbane and Naval Base Sydney. The Royal Australian Navy operated bases in Darwin and worked with the US Navy. Royal Australian Navy base around Darwin: HMAS Coonawarra Naval Base, HMAS Melville Naval Base. *After Victory over Japan Day the base closed and the US Navy started taking Troops home in Operation Magic Carpet.[10][1]
