Britain’s nuclear weapons and submarines are kept at the Faslane naval base in Scotland, which employs thousands of people.
All the pro-independence parties say they’ll disarm the base of its nuclear components but others say that Scotland’s military contribution to the UK is both necessary and beneficial.
At least one nuclear-armed submarine is always on patrol at the Faslane base, providing a continuous at-sea deterrent against potential external attacks. Each of the submarines at the base is armed with a maximum of eight missiles and 40 warheads.
After the Act of Union in 1707, the Scottish army and navy merged with those of England. Scottish soldiers and sailors went on to play a crucial role in expanding the British empire, becoming involved in many international conflicts.
The Scottish National Party and other left wing parties all oppose the deployment of nuclear weapons on Scottish soil, as does most of the public.
