Kate Hollern – 2016 Parliamentary Question to the Ministry of Defence

The below Parliamentary question was asked by Kate Hollern on 2016-02-10.

To ask the Secretary of State for Defence, what percentage optimism bias his Department applied to the Successor Trident programme.

Mr Philip Dunne

Successor submarine is categorised as "Production of a Platform" for optimism bias purposes. In line with normal Ministry of Defence processes, the optimism bias will be addressed as part of the process of securing approval for the next investment point.

I am withholding information for the current calculations for optimism bias, as the formal internal scrutiny process has not been completed.
