[6] Ascension Island's Target Tracking Radar was checked out on January 16, 1961,[4] and used to create recordings of radar reception from Cape Canaveral warheads, "chunks of the booster rocket", and "nose cone decoys" during reentry for use as simulated "ghost" missile input during WSMR's Zeus "synthetic intercept" program.

[6] The HAPDAR (HArd Point Demonstration Array Radar)[12] construction began 16 July 1965 in the former ZAR Receiver building.

[13] The Nike Zeus prototype launching facilities in the design by the Burns and Roe Company[4] was begun in 1959[14] and completed in October 1962.

[15] LC-18 had a Battery Control Building ("contained two Missile Track Radars, the Target Intercept Computer, and data communication equipment"),[11] a Launch Control Building (LCB, now used for the Patriot missile), Launch Cell,[16] tunnel,[17] and nearby tracking radar.

[26] Bell Telephone Laboratories[27] started the Multi-function Array Radar (MAR-I) construction at WSMR for Nike-X in March 1963.
