Object description
The evolution of the submarine and its important rôle as a nuclear deterrent in the Royal Navy and NATO.
Full description
The age of the battleship as a deterrent is over; its role has been replaced by the submarine. Submarines are less vulnerable to aerial attack than surface ships, which is why they have been adopted for Britain's nuclear deterrent. However, a submarine naval blockade could compromise NATO and therefore the RN has also invested in anti-submarine measures. With the aid of diagrams, sonar tracking is explained and its drawbacks analysed. Helicopters can help in a submarine tracking role but also has drawbacks (they need a landing platform). Thus, today, there are submarines hunting submarines in the same environment with their own sonar. Descriptions of the three types of submarine used by the RN: (1) patrol submarines (diesel, patrolling a specific area); (2) fleet submarines (nuclear, doesn't need to resurface periodically); (3) Polaris submarines (basically floating weapons silos). In future, much of the Royal Navy's power will be deployed underwater.
