I guess, we are all expecting the RN to be able to run Our Nuclear Deterrent in a secure and safe as possible manner at all times.
Of course the boats will break-down now and then, like everything mechanical. I expect them to carry snags for a while here and there. But I expect them to be seaworthy before they depart on patrol.
I would also expect security to be tight and hope our authorities are constantly monitoring and testing it.
I would like to see a statement from the Royal Navy giving us assurances that all is well. Unless of course things are actually that bad. If they are, what are Senior Officers doing about it.
This budget is by far the most important and if it needs more spending on it then the RN needs to get it's act together.
