Quite right HAL9000, spot on.
This decision has been made by the government based solely on one issue and one issue alone. COST.
The arguments SHOULD be about whether the job really can save the public money.
6 billion is a lot of savings INITIALLY. Over the 25 yr contract though maybe it isn't. Provided the civilian contractor DOESN'T come back to the table asking for more taxpayers cash to prop up their operation in future, then it's a reasonable deal, I suppose.
However - I would suggest that due to the current MOD climate where everything is being cut back, this project must be up there along with others as sacrificial lambs.
The next election may end up happening before a decision is made with SAR-H. What then !!!
