Just because we don't need Merlin HM1, Typhoon, T45, challenger II now it doesn't mean we won't need them in the Future.
I note Challey II has seen active service in the last few years and as has been mentioned there are many countries with submarines... some of whom may not be our friends this time next week.
Yes budgets are tight and the main focus has to be on current ops but it should not be at the expense of all other capabilities. The UK armed forces has become very very unbalanced and that could cause us major problems in the future when our lightly equipped forces ISTAR assets detect comming over the horizon a heavy force we havn't the capability to stop.
