Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answers of 26 February 2018 to Questions 128460 and 128462, whether his Department holds the average yearly cost per vessel of (a) Type 23, (b) Type 45, (c) Hunt Class, (d) Sandown Class and (e) Albion Class vessels.

The average yearly cost per vessel of each Type 23, Type 45, Hunt Class, Sandown Class and Albion Class vessel could be provided only at disproportionate cost.

Estimated figures for the total yearly cost of operating a Type 31e and Type 26 are not yet available.

The cost of operating a River Class Offshore Patrol Batch 2 Vessel will be determined by the specific operational programmes of the ships when they enter service. We have used the cost of the current in service Batch 1 Offshore Patrol Vessels as the basis of our planning which is £6.5 million per year.
