R-16 (missile)

The R-16 was the first successful intercontinental ballistic missile deployed by the Soviet Union, designed by Mikhail Yangel and Valentin Glushko and built at Plant 586 (Yuzhmash), Glushko's OKB, and Hartron's OKB, achieving initial operational capability on November 1, 1961 after its first flight on February 2 of that year. A true first-generation ICBM and a major improvement over the largely experimental R-7 Semyorka that preceded it, the R-16 used storable, hypergolic liquid propellants, measured 30.4 meters long, weighed 141 tons at launch, and could deliver thermonuclear warheads over a range of 11,000 to 13,000 kilometers. It remained in service until 1976, reaching a peak deployment of 202 missiles in 1965.
