Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what the total projected cost is of the Type 23 frigate capability upgrade programme; how many of that class are planned to receive an upgrade; and what capabilities will be enhanced as part of that programme.

The Type 23 capability sustainment programme will deliver equipment upgrades, depending on the requirement of each ship in the class. This will ensure that these adaptable Frigates continue in service.

With regards to the cost of this programme, this draws together a number of capability enhancements and the information is not held centrally and could be provided only at disproportionate cost.

Regarding detail of the upgrades, it is UK policy that we do not comment on matters relating to individual warship capability as this would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.
