Former USAF Air Def Cmd, 37th Air Defense Missile Squadron 1960-1972 operating 28x nuclear CIM-10s
CIM-10 Bomarc was a supersonic interceptor for Cold War air defense of North America which, in addition to being the first long-range anti-aircraft missile was the only SAM deployed by the USAF.
Stored horizontally in a launcher shelter with movable roof, the aircraft was erected to fire vertically using rocket boosters and then was ramjet-powered during midcourse command guidance to a dive point. During the "homing dive",the missile's onboard AN/DPN-34 radar allowed the BOMARC to guide itself to the target (e.g., enemy bomber or formation) and a radar proximity fuze detonated the 10 kiloton nuclear W-40 warhead.

37th ADMS initially monitored construction of the BOMARC missile facility near Raco, Michigan. The squadron moved to the missile site and was operational by 1 June 1961. By the end of 1961 the squadron stood alert using its complement of 28 CIM-10 BOMARC surface to air antiaircraft missiles. During the 1962 Cuban Missile Crisis, the full squadron stood alert for 27 days. The squadron was tied into a Semi-Automatic Ground Environment (SAGE) direction center which could use analog computers to process information from ground radars, picket ships and airborne aircraft to accelerate the display of tracking data at the direction center to direct the missile site to engage hostile aircraft. As the strategic bomber threat to the US diminished, so did the need for BOMARC missiles and the squadron was deactivated on 31 July 1972. The BOMARC missile site was located at grid 4620′53″N 8448′18″W. Although geographically separated from the base, it was an off base facility of Kinchloe airbase.
