350-043 AMERICAN NUCLEAR-POWERED SUBMARINE SSBN-611 JOHN MARSHALL

USS John Marshall (SSBN-611) is an American nuclear-powered submarine - carrier of nuclear-warhead ballistic missiles (SSBN), the keel of which was laid in April 1960, was launched in July 1961, and was commissioned by the US Navy place in 1962. The total length of the ship at the time of launching was 125 m, width 10.1 m, with an underwater displacement of approx. 7,900 tons. The maximum underwater speed did not exceed 21 knots. The unit had 16 ballistic missile launchers and 4 533 mm torpedo tubes. USS John Marshall (SSBN-611) was the fourth of five Ethan Allen-class ships. This type of units was created as an evolutionary development of the George Washington type and was largely based on the project of the very successful Skipjack hunting submarines. At the same time, they were actually the first SSBN units in the US Navy to be designed and built for this role from the very beginning. The basic armament of the Ethan Allen class ships were 16 Polaris A-2 missiles with a range of up to 4,600 km, capable of carrying (after modernization) three W58 nuclear warheads with a capacity of 200 kT each. The USS John Marshall (SSBN-611) was built at Newport News Shipbuilding, and shortly after entering service was assigned to the Atlantic Fleet, and in July 1962 made its first test launch of a Polaris rocket. The unit spent the period 1962-1980 mainly on patrols and in ports on the Atlantic Ocean. In 1981, in connection with the disarmament agreements, USS John Marshall was reclassified to a fighter submarine, and five years later (1986) it was adapted to transport and partial securing of special units' actions. The unit served actively in the US Navy until 1992, and in 1993 it was completely withdrawn from the line.
