The primary mission of the fleet ballistic missile submarine is deterrence. By deploying these submarines, we are sending aggressor nations a message. That message is that we have nuclear and other strategic weapons on a platform that can be positioned just about anywhere in the ocean and used to retaliate against any nation that is overtly aggressive toward us or our allies.
In the power plants of ballistic missile submarines.
Modern submarines carry a wide variety of weapons. An example of a U.S. Navy Fast-Attack Submarine weapons capability includes: Homing Torpedoes (Active and Passive Sonar) Tomahawk Land-Attack Missile (Conventional and Nuclear) Tomahawk Anti-Ship Missile Harpoon Anti-Ship Missile Mines Ballistic Missile submarines can carry those weapons as well, but their primary mission is Nuclear Deterrence, and as such their main weapons are Submarine Launched Ballistic Missiles (SLBM's).
As of end of 2010, the Russian Navy included 12 strategic submarines of four different types. The submarines can carry 160 sea-launched ballistic missiles (SLBMs) that can carry 576 nuclear warheads.
Propulsion-wise, there are 2 types - Nuclear Powered and Diesel-Electric. Class-wise, there are several: Fast-Attack Ballistic Missile Guided Missile (e.g., Tomahawk)

SSBN stands for "Ship Submersible Ballistic Nuclear" submarine. It refers to a class of submarines designed to carry and launch ballistic missiles armed with nuclear warheads. These submarines are a crucial component of a nation's nuclear deterrent strategy, providing stealth and survivability while maintaining a second-strike capability. SSBNs are typically equipped with advanced technology for navigation, communication, and missile systems.
An intercontinental ballistic missile, or ICBM, is a long-range (greater than 5,500 km or 3,500 miles) ballistic missile typically designed for nuclear weapons delivery, that is, delivering one or more nuclear warheads.Source: Wikipedia.
The Royal Navy Operates 6 Trafalgar class submarines and 1 Astute class. These submarines are called 'attack' or 'hunter-killer' submarines and have roles such as land attack using Tomahawk cruise missiles and anti-surface and anti-submarine roles using the Spearfish torpedo. They can also carry out surveillance and reconnaissanse. The Royal Navy also has 4 Vanguard class submarines. These submarines are ballistic missile submarines. These submarines are responsible for the UK's nuclear detterent and use the Trident missile system. There is always at least one of these boats at sea at any given time.
the nuclear and ballistic missile spheres
The codes are- for conventional () non nuclear powered) Submarines- SS ( for example the U.S.S. is SS-297. Atomic subs are SSN or SSBn - BN if fitted for Ballistic missiles such as the Polaris or Trident types ( there is no Submarine Called the Polaris- it is a guided missile!) so SS- submarine, SSN- Nuclear submarine- SSBN- Nuclear submarine- Missile type.
The hull designator denotes the hull type, it's purpose, and its propulsion mode. For example SSN stands for "Submersible Ship, Nuclear"; SSBN is Submersible Ship, Ballistic, Nuclear; and SSGN is Submersible Ship, Guided Missile, Nuclear. Any vessel that isn't a variant (rare in today's Navy) has a single designation - BB, DD, etc. Nuclear powered vessels are denoted with an "N" in the designation.For submarine hull types, there are currently 3 in the U.S. inventory - SSN, SSGN, and SSBN. SSN's are Nuclear Fast-Attack Submarines - Sturgeon, L.A., Seawolf and Virginia Classes. SSBN's are Ballistic Missile Submarines (Ohio class, etc.) SSGN's are converted older SSBN's that have had their Ballistic Missiles removed as part of the Treaty with the former Soviet Union. They were converted to Cruise Missile launch platforms.
The current total is 71 active and 2 reserve as of May 2011 - Commissioned 14 SSBN's (Ballistic Missile Submarines) 4 SSGN's (Cruise Missile Submarines, converted SSBN's) 53 SSN's (Fast-Attack Submarines) Reserve 2 SSN's (688-class Fast-Attacks) The USS California, the newest Virginia-class SSN, is scheduled for commissioning in October 2011, with another 4 on the way.
