Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the cost to the public purse was of spending on submarines in each financial year since 2019.

The table below shows the values for the procurement of equipment for submarines, as well as equipment support costs for submarines in each complete financial year since 2019.

In addition to the £2.2 billion spend specific to submarines (as shown in column two), the third column in the table shows expenditure on common contracts that support both the surface and submarine fleets.

These figures do not include the cost of operating the platforms, propulsion costs, missiles and capabilities in support of ships and submarines.
