In both images, note the dead-end cable troughs at the corners of the site -- they `confirm` the former presence of four AN/FPS-6 (or -90) height-finder radars (2 for USAF, 2 for Army), as expected. One would have been removed upon FOC of the AN/FPS-26A, and two others would have been removed a few years later for cost savings (as would done at other shared sites supporting Nike Missile-Master operations, e.g., Highlands AFS, NJ).
