Boeing CIM-10B BOMARC rocket

The CIM-10 Bomarc (originally IM-99) was the product of the Bomarc Missile Program. The Program was a joint United States of America–Canada effort between 1957 and 1972 to protect against the USSR bomber threat. The Bomarc was a joint development with Boeing and Michigan Aeronautical Research Center. It involved the deployment of tactical stations armed with Bomarc missiles along the east and west coasts of North America and the central areas of the continent. BOMARC and the SAGE guidance system were phased out in the early 1970s since they seemed to be ineffective and costly. Neither of these systems was ever used in combat, so while their combat effictiveness remains untested, they are still perceived as having been an important deterrent.
