Submarine-launched ballistic missile
From Wikipedia, the free encyclopedia
Image:SNLE-SNLE-NG-vectoriel.png Submarine-launched ballistic missiles or SLBMs are ballistic missiles delivering nuclear weapons that are launched from submarines. Modern variants usually deliver multiple independently targetable reentry vehicles (MIRVs) each of which carries a warhead and allows a single launched missile to strike a handful of targets.

[edit] Description
As early as 1934, H. G. Wells predicted, in his The Shape of Things to Come, the use of submarines carrying "long-range air torpedos with directional apparatus". Though he envisaged these as carrying a chemical rather than nuclear warheads, he grasped the far-reaching strategic implications: "The smallest of these raiders carried enough of such stuff to 'prepare' about eight hundred square miles of territory; it could have turned London or New York into a cityful of distorted corpses. These vessels made London vulnerable from Japan, Tokyo vulnerable from Dublin; they abolished the last corners of safety in the world."
The first successful tests of a submarine-based launch platform were by German U-boats in World War II using a submarine towed launch platform. These and other early SLBM systems required vessels to be surfaced when they fired missiles, but after World War 2, launch systems were quickly adapted to allow underwater launching. In September of 1955, the Soviet Union was the first country in the world to launch a ballistic missile from a submarine.
Ballistic missile submarines have been of great strategic importance for the USA and Russia since the Cold War, as they can hide from reconnaissance satellites and fire their nuclear weapons without much warning, even close to the opponent's coast.
Numerous international press reports since the middle 1990s attribute to Israel a policy of mounting missiles with nuclear warheads on the submarines it obtained from Germany, for use especially in the event of Iran developing nuclear arms of its own. The government of Israel persistently denies all such reports, though they will neither confirm nor deny whether they have nuclear weapons.
