The Army's [[Johnston Atoll Chemical Agent Disposal System]] (JACADS) was the first full-scale chemical weapons disposal facility. Built to incinerate chemical munitions on the island, planning started in 1981, construction began in 1985, and it was completed five years later. Following construction and facility characterization, JACADS began operational verification testing (OVT) in June 1990. From 1990 until 1993, the Army conducted four planned periods of Operational Verification Testing (OVT), required by Public Law 100–456. OVT was completed in March 1993, demonstrating that the reverse assembly incineration technology was adequate and that JACADS operations met all environmental parameters. The transition to full-scale operations started in May 1993, but the facility did not begin full-scale operations until August 1993.

All of the chemical weapons once stored on Johnston Island were demilitarized, and the agents incinerated at JACADS, with the process completed in the year 2000. Later, the destruction of legacy hazardous waste material associated with chemical weapon storage and cleanup was completed. JACADS was demolished by 2003, and the island was stripped of its remaining infrastructure and environmentally remediated.<ref name="cma.army.mil"/>
