NAB,
Having exactly one Ship of a Six Ship Class in Port for any reason that prevents them from being at Sea on Ops is not a good thing.
Scheduled maintenance periods should ensure the Fleet capability is not harmed by yard periods.
Having unreliable Engines in all of them really isn't a good thing with unscheduled repairs and/or modifications impacting operational capability being a very bad thing.
Today's Royal Navy's throw weight has been so reduced it might consider sticking to Fishing Wars where it might have a chance for success.
I am not slighting the Crews....just the Politicians that have seen to make cuts in Defense Spending in exchange for social welfare spending.....something we suffer from as well.
The lack of ability of Nations to rapidly replace losses of aircraft and ships suggests the next major War is going to be short and ugly with a very great risk of going nuclear.
At some point there is bound to be another War....Politicians seem to have a real ability to get us into those situations.
All that has to be done is to look at the World's shared Histories.....seems there's conflict and combat going on somewhere on the Globe all of the time.
