KREMS is that portion of the RTS that con- tains a suite of the world’s most powerful and precise instrumentation radars. KREMS is named after U.S. Army Lieutenant Colonel Joseph M.

The Reagan Test Site is located in the central Pacific on the world’s largest atoll. This atoll is about equidistant from Hawaii, Australia, and the Philippines (a). The world’s most sophisticated instrumentation radars are located on Roi-Namur island (b) at the northern extent of the atoll. Most personnel manning the site continue to reside on the southernmost Kwajalein Island (c).

NELSON AND KENNETH R. ROTH Honoring LTC Kiernan Lieutenant Colonel Joseph M. Kiernan Jr., the son of a captain in the U.S. Navy, was commissioned in the Army after his graduation from the U.S. Mili- tary Academy at West Point. The top graduating senior in the class of 1948, he was assigned to the 1st Engineering Battalion of the 1st Infantry Division (nicknamed the Big Red One). After earning a master’s degree at the Cali- fornia Institute of Technology, Kier- nan was assigned to the Missiles and Space Division of the Office of the Chief of Research and Development. His expertise in missile technology led to his Pentagon assignment in the Advanced Research Projects Agency (ARPA) and to Project PRESS. During a critical three-year period of growth and consolidation, 1963– 66, Project PRESS was energized by the leadership and presence of LTC Upon completing his tour of Legion of Merit, the Distinguished Kiernan.
