Question to the Ministry of Defence:

To ask Her Majesty's Government what assessment they have made of how robust in terms of (1) price, and (2) delivery, the approved business case is for the procurement of the Boeing E-7 Wedgetail.

All Ministry of Defence (MOD) business cases undergo rigorous assessment in accordance with Joint Service Publication 655, which includes assessments of both cost and deliverability. An outline business case to replace the existing capability delivered by the E-3D Sentry fleet was submitted to the MOD Investment Approval Committee in December 2018. This was subject to approval by MOD Head Office and HM Treasury.
