Johnston Atoll is a US territory covering about 50 square miles of islands in the remote Pacific Ocean. From 1934 to 2003, it was under the control of the US Navy and was used as launch site for nuclear testing and super-secret experimental aircraft and who knows what else. The base was abandoned when the atoll was turned over to the US Fish and Wildlife Service. See photographs from various phases of the base's history at Urban Ghost Media. http://www.urbanghostsmedia.com/2010/04/isolated-and-abandoned-military-airbase-johnston-atoll/

...and now a chemical incinerator?
Wow, this place IS a pacific paradise!
It was actually under the control of the US Air Force, but the army provided soldiers for physical security and to move the chemical agents from the bunkers to the incinerator plant.
