The F-35 Joint Program Office places contracts to support and maintain the global fleet of F-35 aircraft, including those operated by the UK. It places the support and maintenance contracts through its two main prime contractors, Lockheed Martin and Pratt and Whitney. These two companies then place contracts across and through the F-35 global supply chain, including UK based companies. These include maintenance and repair contracts, initial and replenishment spares, and technical support.
Further to my answer to the hon. Member on 2 March 2021 to questions 158864 and 158865, I will be writing to him shortly regarding UK industrial content in the F-35 programme.
