Question: (2) what the projected cost to the public purse is of long-lead items for purchase ahead of the Trident replacement main gate decision.

Answer: The programme to replace the Vanguard class has still to enter the assessment phase. The initial gate business case for the assessment phase of the programme is currently being reviewed. It is not possible to confirm the value of long-lead items or assessment phase provision before the assessment phase programme has been approved. Moreover, we do not routinely publish figures for anticipated project expenditure, as to do so would prejudice commercial interests.
