Both the US and the Kingdom of Hawaii annexed Johnston Atoll in 1858, but it was the US that mined the guano deposits until the late 1880s. Johnston and Sand Islands were designated wildlife refuges in 1926. The US Navy took over the atoll in 1934, and subsequently the US Air Force assumed control in 1948. The site was used for high-altitude nuclear tests in the 1950s and 1960s, and until late in 2000 the atoll was maintained as a storage and disposal site for chemical weapons. Munitions destruction is now complete. Cleanup and closure of the facility was completed by May 2005. The Fish and Wildlife Service and the US Air Force are currently discussing future management options, in the interim Johnston Atoll and the three-mile Naval Defensive Sea around it remain under the jurisdiction and administrative control of the US Air Force.
