The Government could also opt to make use of the military’s Type 45 destroyer vessels, which could use their defensive capabilities to fend off any nuclear attack.
For example, if it was deemed necessary, these ships could be placed in the Thames Estuary to defend London and the surrounding areas.
Since April 1969, the Royal Navy has maintained continuous at sea deterrence, with at least one nuclear-armed ballistic missile submarine patrolling the seas undetected at all times.
Their fundamental purpose is to preserve peace, prevent coercion, and deter aggression.
