On-Site Inspection Agency (OSIA) Collection

The 1987 Intermediate-Range Nuclear Forces (INF) Treaty between the United States and the Soviet Union eliminated nuclear and conventional ground-launched ballistic and cruise missiles with ranges of 300 to 3,200 miles. The treaty was the first nuclear arms control treaty to require the destruction of an entire class of nuclear-armed missiles and to permit on-site inspections to help verify compliance. President Ronald Reagan directed the Department of Defense (DOD) to create the On-Site Inspection Agency (OSIA) in 1988 to carry out US inspections in the USSR, Czechoslovakia, and East Germany and to escort Soviet inspectors in the United States, West Germany, Belgium, the Netherlands, Italy, and the United Kingdom. As a result of the INF Treaty, the United States and the Soviet Union destroyed a total of 2,692 short-, medium-, and intermediate-range missiles by the treaty's implementation deadline of June 1, 1991. Martin Lee Klug was Deputy INF Program Manager (1989–1990) and then INF Program Manager (1991–1995) at the Martin Marietta plant (former Pershing 1 launcher production facility) at Middle River, Maryland.
