A Chinese-owned company is making circuit boards for the top secret next generation F-35 warplanes flown by Britain and the United States, Sky News can reveal.

Exception PCB, a printed circuit board (PCB) manufacturer in Gloucestershire, south west England, produces circuit boards that "control many of the F-35's core capabilities", according to publicity material produced by the UK Ministry of Defence (MoD).

This includes "its engines, lighting, fuel and navigation systems", it said.

When asked about the firm's Chinese ownership, the MoD said Exception PCB is an established manufacturer of circuit boards to the defence industry and presents "no risk" to the F-35 Joint Strike Fighter supply chain.
