Ballistic missile submarine
A ballistic missile submarine is a submarine capable of deploying submarine-launched ballistic missiles (SLBMs) with nuclear warheads. These submarines became a major weapon system in the Cold War because of their nuclear deterrence capability. They can fire missiles thousands of kilometers from their targets, and acoustic quieting makes them difficult to detect (see acoustic signature), thus making them a survivable deterrent in the event of a first strike and a key element of the mutual assured destruction policy of nuclear deterrence. The deployment of ballistic missile submarines is dominated by the United States and Russia (following the collapse of the Soviet Union). Smaller numbers are in service with France, the United Kingdom, China and India; North Korea is also suspected to have an experimental submarine that is diesel-electric powered.[1][2]
Ballistic missile submarines should be distinguished from so-called nuclear submarines, which does not refer to a submarine carrying nuclear weapons, but instead refers to submarines with a nuclear propulsion engine.
Terminology[edit]
United States and United Kingdom[edit]
In the US Navy, SSBNs are sometimes called Fleet Ballistic Missile submarines, or FBMs. In US naval slang, ballistic missile submarines are called boomers. In the UK, they are known as bombers.[32] In both cases, SSBN submarines operate on a two-crew concept, with two complete crews – including two captains – called Gold and Blue in the United States, Starboard and Port in the United Kingdom. The designation SSBN is also used throughout NATO under STANAG 1166.[33]
France[edit]
The French Navy commissioned its first ballistic missile submarines as SNLE, for Sous-marin Nucléaire Lanceur d'Engins (lit. "nuclear-powered device-launching submarines"). The term applies both to ballistic missile submarines in general (for instance "British SNLE" occurs [34]) and, more technically, as a specific classification of the Redoutable class. Its successor, the Triomphant class, is referred to as SNLE-NG (Nouvelle Génération, "New Generation"). The two crews used to maximise the availability time of the boats are called "bleu", (blue) and "rouge", (red) crews.
Soviet Union and Russian Federation[edit]
The Soviets called this type of ship RPKSN[35] (lit. "Strategic Purpose Underwater Missile Cruiser"). This designation was applied to the Typhoon class. Another designation used was PLARB(«ПЛАРБ» – подводная лодка атомная с баллистическими ракетами, which translates as "Nuclear Submarine with Ballistic Missiles"). This designation was applied to smaller submarines such as the Delta class. After a peak in 1984 (following Able Archer 83), Russian PLARB deterrence patrols have declined to the point where there is less than one patrol per sub each year and at best one sub on patrol at any time. Hence the Russians do not use multiple crews per boat.[36]
