What are the differences between classes of submarines?
“Hunter killer” submarines (designated SSNs by the RN) are designed to pursue and attack enemy submarines and surface ships using torpedoes. They are also able to carry “cruise” missiles for use against shore-based targets. This type of submarine is used to conduct surveillance and intelligence gathering tasks as well as other types of classified operations. Ballistic missile submarines (designated SSBNs) carry long-range nuclear warhead missiles. They roam the oceans of the globe avoiding contact, to ensure that their anonymity is not compromised. The ability to strike at any time has ensured that deterrent value of SSBNs, or “Bombers”, has proved effective in preventing attack on the UK.
