This is a model of unknown scale of the SAM-5, a Soviet ground-launched anti-aircraft missile also believed to have potential use as an anti-ballistic missile. One of the largest anti-aircraft missiles ever developed, the SAM-5 has either a conventional or nuclear warhead, a maximum speed of Mach 4, a range of 155 miles, and a ceiling of 100,000 feet. Beginning in the 1960s, it was deployed in the Soviet Union and Warsaw Pact nations. Today the missile is deployed only in Russia. The model's manufacturer is unknown.
