Usacap Johnston Atoll

USACAP Johnston Atoll, officially known as the United States Army Chemical Activity Pacific, was established in the 1970s on Johnston Atoll in the Pacific Ocean. The unit was primarily responsible for the safe storage, management, and eventual destruction of the U.S. chemical weapons stockpile located on the atoll. USACAP Johnston Atoll operated the Johnston Atoll Chemical Agent Disposal System (JACADS), the first full-scale chemical weapons destruction facility in the world, which began operations in 1990. The unit completed its mission with the destruction of the last chemical munitions in 2000, and the facility was closed and dismantled by 2003, marking the end of the Army’s permanent presence on Johnston Atoll.
