Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what upgrades the Sentinel R1 aircraft is receiving; and what the (a) purpose, (b) cost to the public purse and (c) completion date of those upgrades is.
I refer the hon. Member to the answers I gave on 1 September 2014, (Official Report, column 103W), to him and to the hon. Member for North Durham (Mr Kevan Jones). I am withholding technical details of the upgrades as their disclosure would, or would be likely to, prejudice the capability, effectiveness or security of the Armed Forces.
