asked the Secretary of State for Defence when he hopes the T2400 submarine will come into service in the Royal Navy.

asked the Secretary of State for Defence how much money has been allocated for the development contract of the T2400 submarine; and how much has been spent.

asked the Secretary of State for Defence what is the present estimated unit cost of the T2400 submarine.

It is not the practice to reveal precise unit costs in advance of placing an order. Costs depend on the outcome of detailed negotiations between the Ministry of Defence and contractors, and it is not possible to give a firm figure until the contract negotiations are complete. However, our aim is that the unit cost of the T2400 submarine should be less than half that of a new nuclear submarine.
