Question to the Ministry of Defence:

To ask the Secretary of State for Defence, pursuant to the Answer of 18 May 2021 to Question 1009 on Chinook Helicopters: Procurement, for what reason there is a discrepancy in the reported sales cost for Extended Range Chinook Helicopters between (a) £1.4 billion stated in that answer and (b) £2.8 billion stated in the 2018 Defence Security and Cooperation Agency.

The Approved Budgetary Level for the acquisition of 14 Chinook H-47 Extended Range Helicopters of £1.4 billion is based on the Foreign Military Sale case value received in 2020. The earlier estimate, as published by the US Defense Security Cooperation Agency, was prepared in advance of the final agreed cost and included the potential provision for a further two aircraft if requested.
