.....and is a subcontractor to Pratt & Whitney who is part of United Technologies Corp who build the F-35B engine with Rolls-Royce Plc......
Hang on, correct me if I'm wrong but isn't the fault on the F135 engine? If so, what part of that do Rolls Royce build?
My understanding is that Rolls Royce build the 'vertical lift module' (shaft-driven fan bit at the front) and were involved in the development of the alternative F136 engine.
