Question to the Ministry of Defence:

To ask the Secretary of State for Defence, what assessment he has made of the potential impact of replacing retiring Tranche 1 Typhoon aircrafts with foreign-built aircraft on (a) BAE Systems sites at (i) Warton and (ii) Samlesbury and (b) the UK aerospace sector.

The RAF's fleet of Typhoon Tranche 2 and 3 aircraft will remain at the cutting-edge of the UK and NATO Combat Air power until at least 2040. The decision in 2021 to retire our oldest Tranche 1 Typhoon aircraft was independent of the decision to procure Lockheed Martin F-35B, which are required to deliver combat aircraft capable of operating from our Queen Elizabeth Class aircraft carriers.

Around 20,000 people are employed within the UK on the Typhoon programme, which is expected to rise to 24,000 by 2030. The vast majority of those jobs support the maintenance and upgrade of the existing multinational Typhoon fleet. This Government is strongly committed to supporting the export of Typhoon internationally and pressing for success in the campaigns currently in train. 37% of the major units required for new Typhoon aircraft ordered by Germany, Spain and Italy will be manufactured by BAE Systems in the UK.

In addition, through Lockheed Martin and the Joint Program Office approximately 15% by value of the total global F-35 Lightning production is manufactured by UK companies. This manufacturing and equipment support includes over 100 UK-based suppliers and has created over 20,000 jobs in the UK. As part of this BAE Systems employ approximately 1,800 people on F-35 sub-system production at their UK plant in Samlesbury. The equipment support provided by the UK for the global fleet of F-35 will likely endure until the F-35 retires from service, which is 2069 for the UK fleet and longer for some other nations.
