🚨 Three of the UK’s four nuclear deterrent submarines are out at sea, it is understood.
It is not clear why but at least one of the boats will be armed with nuclear warheads and on routine patrol.
An expert said one of the other Vanguard-class submarines would likely be working up to take over the patrol, while the third could be undergoing sea trials.
The Ministry of Defence declined to comment.

The unusual deployment of most of the fleet indicates improved availability, which has been a problem for the Royal Navy’s submarine service in recent years.
It will doubtless be noticed by the UK’s enemies.
