Question to the Ministry of Defence:

To ask the Secretary of State for Defence, if he will publish his Department's reasons for installing an Engineered Material Arresting System at RAF Northolt; how much he expects that installation to cost; and if he will make a statement.

The Engineered Material Arresting System (EMAS) is being scoped as a military infrastructure requirement commensurate with safety cases for military aircraft operating at RAF Northolt and the associated military aerodrome design standards utilised at the Station. I am withholding estimated costs for the EMAS project as it is at the pre-tender stage and disclosure would or would be likely to prejudice commercial interests.

The Mott McDonald report has no opinion or relevance against the military aerodrome design criteria and safety cases in place at the Station or the current operation of RAF Northolt. Any infrastructure investment for military operational requirements will continue to be undertaken as necessary to support military and Government outputs.
