Engines,
Thanks again for getting back to me.
Regarding 3F software, I also understood that the software was meant to have been released by now, as yet I have not seen a photo of a F35, that is not part of the test fleet with external stores, makes me think that 3F has yet to be released. Although I have read somewhere that 3F has been released, with no linked source as I recall.
As I understood it plan A was that all F35s would in the end be on the same level of software, implicitly any necessary technical refreshes necessary would have to be installed.
My concern is that IF the USAF has decided NOT to upgrade their early LRIP F35s, where will the UK ones be upgraded and where the funding for the upgrade comes from?
Apologies if I have misunderstood your response.
Philip
