What is the difference between fast attack (SSN) and fleet ballistic missile (SSBN) submarines?
Fast attack submarines (designated as “SSNs” by the U.S. Navy) are designed to pursue and attack enemy submarines and surface ships using torpedoes. They also carry cruise missiles with conventional high-explosive warheads to attack enemy shore facilities. Fast attack submarines launched cruise missiles against targets in Iraq during Operation Desert Storm and targets in Serbia during the conflict in Kosovo. They also conduct intelligence, surveillance and reconnaissance missions, mine laying and support special operations, among other types of classified operations. Fleet ballistic missile submarines (designated as “SSBNs”) carry long-range nuclear warhead missiles. They roam the ocean avoiding contact with other submarines and surface ships. The ability of the fleet ballistic missile submarine to survive a nuclear attack against the United States made them the most credible deterrent during the Cold War. The fleet ballistic missile submarines could be ordered to retaliate by launchin
