What a load of codswallop, The SSBN's are based at Faslane and the warheads at RNAD Coulport, both in Scotland.
The Trident missiles are rotated between the US/UK and maintained in the US but the Warheads are built, stored and maintained in the UK!
"One of the most common myths around the system is that the United States has control over the UK’s Trident missile system, that is not the case.
It’s often said that the UK’s Trident nuclear weapons system is not ‘independent’ or that the UK doesn’t have the ability to use the system without the US agreeing to it, in reality the UK does retain full operational control over the system.
One common argument is that the US can simply ‘turn off’ the GPS system and therefore can stop the UK using Trident, this is also a myth, Trident isn’t guided by satellite."
No, America doesn’t control Britain’s nuclear weapons
