PARCS
The acronym, PARCS, stands for Perimeter Acquisition Radar attack Characterization
System. This huge structure was built as the main sensor for the Army`s Safeguard
missile system that deployed north of Grand Forks, North Dakota. Upon shutdown of
Safeguard in 1976, the Air Force took over the huge UHF phased-array radar for use
in tracking ballistic missiles and objects in space.
