description

Summary

Significance: It is believed that the plans for deployment and initiation of construction of this facility were instrumental in obtaining Soviet agreement to the Anti-Ballistic Missile Treaty and a subsequent decline in Cold War hostilities between the Superpowers. The Perimeter Acquisition Radar Building (PARB) is the only structure of its kind and size in the world. A unique massive, structure, for some time it was the second largest building in the state of North Dakota. The structure, which is steel reinforced concrete, was built to withstand a nuclear blast, termed nuclear hardened. The Perimeter Acquisition Radar is a long-range, phased array radar. It faces north and provides surveillance over the polar region. It can detect and track multiple targets. After the termination of the Safeguard system, the PAR became part of the missile early warning network and has remained operational to date.
Survey number: HAER ND-9-P
