From the information revealed by the Open origin Intelligence analysts, no of the British, impacted atomic submarines have sailed to sea for 47 days. The reason for this circumstantial “ground” is to be the backlog in the maintenance of individual units. However, this problem does not apply to the British fleet of atomic submarines with ballistic missiles, which form the backbone of the British CASD (Continuous At Sea Deterrent) deterrence system. The 4 Vanguard-type boomers of this fleet are inactive in constant operational readiness and carry out on-call missions.
