Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what is the (a) original and (b) current cost expectations for the Core Production Capability programme.

The original expected programme cost to completion at initial approval was £1,385 million. The current programme expected cost to completion is £1,822 million. The cost increase is due to changes in programme scope since initial approval along with the combination of additional submarine core manufacturing and facility regeneration costs.
