The radar was a medium power D-Band search radar designed for aircraft control and early warning, and was installed at commercial airports and military bases both in the United States and overseas. In most installations the antenna was exposed, being mounted on a temporary tower.

For severe environmental conditions, the AN/FPS-8 was self-contained in an arctic tower with a protective radome. Over the years improvements were made to the basic AN/FPS-8, culminating in the final version whose nomenclature was AN/FPS-88 (V). The AN/FPS-8 also had two mobile versions: the AN/MPS-11 and the AN/MPS-11A.
