Nike Base was built as the Cold War peaked. Ajax and Hercules missiles were placed in underground launching silos between Oxford and College Corner in 1960. The Oxford Nike Base, its common name, was north of U. S. 27, off Todd Road, about two miles west of Oxford. It was one of four missile bases circling the Greater Cincinnati area, all operational in February 1960. The other sites were at Wilmington and Felicity in Oxford, and at Dillsboro in Indiana. The $3 million Oxford base -- officially called an anti-aircraft facility -- had four underground bunkers. The 14-acre, 14-building complex also included barracks, offices and missile control and monitoring facilities, staffed by 40 men. By the late 1960s, new long-range weapons made obsolete the Oxford base, and others like it. The base closed early in 1970 and was declared surplus property by the government in July 1970. It was acquired by Miami University's Institute of Environmental Services.
