The case for eliminating the carrier force was far more complicated than you make out, but eventually came down to the fact we couldn't afford the three that would have been required.
The situation in today is similar. The situation is not that a case cannot be made made for the SHAR, it can. It is that better cases can be made for other capabilities.
If you wish to find the money to refurbish and retain the SHAR, the money must be found from eslewhere in the RN budget. Please explain where. Because, in the present climate, you will not get extra from the treasury.
And if I were you, I'd start worrying about where they plan to find the extra £3 billion for the new carriers as well. Now about those SSN boats and their reactors........
