The "Atomic Tank" was a Centurion tank which was placed 500 m (1,600 ft) from ground zero of a 10Kt atomic bomb test at Woomera in 1953. It was damaged but still driveable, was repaired and served in Vietnam, before being used as a "gate guardian" at Robertson Barracks.[3]
In 2011 as part of the Obama administration's "pivot to Asia" it was announced that US Marines would be based in Darwin at the Robertson Barracks. In November 2011 it was announced that up to 2,500 US Marines would be based in Australia for training, starting from 200 to 250 in 2012, to 2500 over the following five years. The Marine groups were to stay for six months at a time.[6][7][8]
Robertson Barracks is reported to be a future site of a United States Pacific Command, Marine Rotational Force-Darwin (MRF-D), and its current capacity of 4,500 troops will be upgraded in the near future. Currently, the size and the accessibility of key facilities in Darwin follows closely with other US deployment sites around the globe.[citation needed]
In 2016, 1,250 US Marines deployed to Robertson Barracks, along with four UH-1Y Venom helicopters.[9]
Drawn-out negotiations over cost-sharing and other issues meant that the original number of 2,500 Marines per deployment would not be reached until at least 2020.[10]
As of February 2024[update], it was reported that up to 2,500 Marines had been stationed at Darwin each year.[11]
