Conclusion
The Department told us that its intention to buy 138 aircraft was based on its original plan that there would always be four operational squadrons and both carriers operating. The 2015 Strategic Defence and Security Reviews altered this expectation, and the Department now regards Carrier Strike’s full operating capability as being two UK Lightning II squadrons (up to 24 jets) operating from one of the carriers. It aims to achieve this by the end of 2023. The Department assured us that having 48 aircraft by 2025– 26 would be adequate to deliver two squadrons in normal circumstances.39 However, it acknowledged that the attrition rate in a high-intensity war would mean it could not sustain two squadrons, which would very much reduce a carrier’s utility.40

4a: PAC recommendation: It should provide the Committee with a full and detailed breakdown of Lightning II related expenditure to date, the approved budget and the forecast whole life costs of the Programme. 4.1 The government agrees with the Committee’s recommendation. Target implementation date: January 2021 4.2 The department has arranged for a private briefing session on 20 January 2021 to discuss Lightning II related expenditure. To note: The briefing date has been agreed with the Committee, however, this does not meet the recommendation timeline (within one month). 4.3 The briefing will cover the Whole Life Costs (WLC) of the 48 F-35 aircraft that the department is currently committed to purchase and includes the current programme approval levels. The procurement strategy for Lightning II is one of incremental acquisition and was approved at Main Gate 2 in 2006. This strategy tied the UK to a through-life collaborative partnership within the Joint Strike Fighter Programme, using the governance and procurement processes set out in the Production, Sustainment and Follow-on Development memorandum of understanding. 4.4 The WLC model considers all the acquisition phases from Lightning inception to aircraft disposal and are based upon the current mandate for 48 F-35Bs with an out of service date of 2048. The costs do not include operating costs such as service delivered manpower, fuel and weapons expenditure that are covered under separate Top-Level Budgets.
