The Hughes AN/TSQ-51 Air Defense Command and Coordination System[1] was a transportable electronic fire distribution center for automated command and control of remote Nike missile launch batteries. The radar netting system replace the vacuum tube AN/FSG-1 in 6 United States Missile Master bunkers after the upgrade was approved by the United States Department of Defense in 1963; and additional deployments were at Homestead-Miami, Florida, and Providence, Rhode Island, to replace Battery Integration and Radar DIsplay Equipment (BIRDIE) systems;[2] as well as at San Francisco.[3] As with the AN/FSG-1, the AN/TSQ-51 could provide fire control for 24 Nike batteries,[4] but the smaller AN/TSQ-51 could be fielded in 2 trailers.
