Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 26 February 2018 to Question 128462, whether his Department has estimated figures for the total yearly cost of operating the following the (a) Type 26, (b) Type 31e and (c) River Class OPV Batch 2 vessels when in service.

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.
