Aircraft Warning Corps

The Aircraft Warning Corps (AWC) was a World War II United States Army Air Force organization for Continental United States air defense. The corps' information centers networked an area's "Army Radar Stations" which communicated radar tracks by telephone, and the information centers also integrated visual reports processed by Ground Observer Corps filter centers. The AWC notified air defense command posts of the First Air Force, Second Air Force, Third Air Force, and Fourth Air Force. These command posts would deploy interceptors which used command guidance to achieve ground-controlled interception.

United States electronic attack warning began with the 1929 Air Corps "experimenting with a rudimentary early-warning network at Aberdeen Proving Ground" in Maryland, a 1939 networking demonstration at Twin Lights station (New Jersey), and 2 SCR-270 radar stations during the August 1940 "Watertown maneuvers" (New York). When "Pearl Harbor was attacked, [there were 8 CONUS] early-warning stations" (Maine, New Jersey, and 6 in California), and Oahu's Opana Mobile Radar Station had 1 of 6 SCR-270s.

CONUS Army Radar Station deployments after Pearl Harbor were primarily for anti-aircraft coastal defence, e.g., L-1 at Oceanside, California, B-30 at Lompoc, California, and J-23 at Tillamook Head (Seaside, Oregon). California's B-78 Mount Tamalpais Radar Station, subsequently became a Cold War station of the Lashup, Permanent, SAGE, and JSS radar networks. Aircraft Warning Battalions included: 551st at tbd, 555th at tbd, 558th, and 599th (Drew Field, Tampa: 30 March 1944).
