R-16
Encyclopedia
The R-16 was the first successful intercontinental ballistic missile
deployed by the Soviet Union
. In the West it was known by the NATO reporting name
SS-7 Saddler, and within Russia, it carried the GRAU
index 8K64.
(CEP) of 2.7 km.
After the delays associated with the deaths of most people working on the project, the first flight of the missile took place on 2 February 1961. Initial operational capability was achieved on 1 November 1961. The missile continued to serve until 1976, with maximum deployment numbers reached in 1965 with 202 missiles deployed. The Soviets had fewer than 50 of these missiles deployed in 1962 during the Cuban Missile Crisis
. It is possible that only around 20 interim R-16 launchers were operational during the height of the crisis.
The R-16 was a true first-generation intercontinental missile and a vast improvement over the largely experimental 'zeroth' generation R-7 Semyorka
. Unsymmetrical dimethylhydrazine bipropellant used in R-16. It was initially deployed at soft sites which were not shielded from nuclear attack. On normal duty the missiles were stored in hangars, and it took one to three hours to roll them out, fuel them, and reach launch readiness. The missiles could remain fueled for only a few days due to the corrosive nature of the nitric acid
fuel oxidant. After this, the fuel would have to be removed and the missile sent back to the factory for rebuilding. Even when fueled and in an alert posture, the Soviet
missiles still needed to wait up to twenty minutes to spin up the gyroscopes in their guidance systems before launch was possible. Despite these shortcomings, the R-16 was unquestionably the first truly credible rocket-based strategic nuclear deterrent developed by the Soviet Union.
The Soviets were aware of the missile's vulnerability, and from 1963
onward some R-16U missiles were based in silos, with around 69 silo launchers put into service. Each launch complex consisted of three silos clustered together for economic reasons to allow them to use a common refueling system, making them vulnerable to a single U.S. missile.

Description
The missile was over 30 m long, 3.0 m in diameter and had a launch weight of 141 tons. The maximum range was 11,000 km with a 5-6 Mt thermonuclear warhead and 13,000 km with a 3 MT warhead. The missile had a circular error probableCircular error probable

History
During development, a massive failure occurred on October 24, 1960, when a prototype rocket exploded on the pad killing over 100 personnel. After decades of government coverup, this incident, referred to as the Nedelin disaster, was finally revealed.After the delays associated with the deaths of most people working on the project, the first flight of the missile took place on 2 February 1961. Initial operational capability was achieved on 1 November 1961. The missile continued to serve until 1976, with maximum deployment numbers reached in 1965 with 202 missiles deployed.

The R-7 was a Soviet missile developed during the Cold War, and the world's first intercontinental ballistic missile. The R-7 made 28 launches between 1957 and 1961, but was never deployed operationally. A derivative, the R-7A, was deployed from 1960 to 1968...
