Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the projected whole life costs of Sea Venom (a) were originally and (b) are as of 13 October 2023.

The original Sea Venom Business Case from 2012 provided a cost of £452 million for the demonstration and manufacture phases of the project. The current forecast is £493.8 million. These figures do not include the integration costs associated with the project, including ship modification costs, as these were transferred into the Martlet Business Case in 2013. Through life support cost estimates are commercially sensitive.
