UK industry is making a significant contribution to the F-35 programme, providing 15% by value of every F-35 built. With regard to the Rolls-Royce lift fan system, approximately 70% of the development work and 40% of the production work is carried out in the UK. Given the nature of the supply chain, the Ministry of Defence does not hold further detailed information on the value of UK F-35 work that is specifically attributable to the lift fan.
