The Cape Cod system reached Initial operating capability (IOC) as the Cape Cod Missile Early Warning Station on 4 April 1981 with initial operational test and evaluation (IOT&E) completed 21 May; Beale AFB reached IOC on 15 August. The two PAVE PAWS, three BMEWS, and the PARCS & FPS-85 radar stations transferred to Strategic Air Command (then Space Command) in 1983. By 1981 Cheyenne Mountain was providing 6,700 messages per hour including those based on input from the PAVE PAWS and the remaining FSS-7 stations. In 1981, as part of the Worldwide Military Command and Control System Information System (WIS), the Pentagon's National Military Command Center was receiving data "directly from the Satellite Early Warning System (SEWS) and directly from the PAVE PAWS sensor systems".
