UGM-27 Polaris - Strategic Role

Strategic Role

The Polaris A-1 missile was developed to complement the limited number of medium-range systems deployed throughout Europe. As those systems lacked the range to attack major Soviet targets, Polaris was developed to increase the level of nuclear deterrence. At this time there was little threat of counterforce strikes, as few systems had the accuracy to destroy missile systems. The primary advantages of ballistic missile submarines was their ability to launch submerged, which offered improved survivability for the submarine while also (like their Regulus predecessors) move shorter ranged systems within range.

The USN had forward-basing arrangements for its Atlantic-based Polaris fleet with both the United Kingdom and Spain permitting the use of bases at the Holy Loch in Scotland and at Rota in the Bay of Cadiz that were much closer to patrol areas, avoiding the necessity for lengthy transit times from U.S. East Coast bases. This forward-basing arrangement was continued when Poseidon replaced Polaris. Polaris was not accurate enough to destroy hardened targets but would have been effective against dispersed surface targets, such as airfields, radar and SAM sites, as well as military and industrial centers of strategic importance. The military authorities, however, regarded Polaris as but one of a nuclear triad, each with its own function. The task allotted to Polaris of 'taking out' peripheral defenses was well-suited to its characteristics and limitations.

Famous quotes containing the words strategic and/or role:

    Marriage is like a war. There are moments of chivalry and gallantry that attend the victorious advances and strategic retreats, the birth or death of children, the momentary conquest of loneliness, the sacrifice that ennobles him who makes it. But mostly there are the long dull sieges, the waiting, the terror and boredom. Women understand this better than men; they are better able to survive attrition.
    Helen Hayes (1900–1993)

    Our role is to support anything positive in black life and destroy anything negative that touches it. You have no other reason for being. I don’t understand art for art’s sake. Art is the guts of the people.
    Elma Lewis (b. 1921)
