It was wrong of Mr Cameron to try to score political points over this before, just as it's wrong for you to try and settle the score:
"Ah well, only £50million down the drain."
If you or David Cameron are the slightest bit interested in the way MOD procurement then: -
The organisation develops a six phase procurement plan, the first part of which involves developing a range of options. The preferred option (and non-prefeered) pass through an initial gate business case process which includes technical appraisals as well as involvement by the Treasury in assessing the economic business case. Because these projects never involve buying something straight off the shelf, industry partners are involved in providing proposed solutions and their outline costs. One of the main issues in the costings is the price of risk - these are the 'unknowns' and there are sophisticated models used to cost these risks. As the solution develops, the risks either come to bear or are mitigated. Sometimes risks are mis-estimated or aspects to risk are not even considered - so costs can escalate.
The £50m you refer to has not been poured down the drain - it has partly been spend on labour costs with potential suppliers in the UK and has thus supported badly-needed UK jobs. I'd have thought you might have considered that important. But the work have have to be redone for the new solution so a cost to the Exchequer.
