Feels like we're missing a piece of the puzzle in this story. Maybe something else happened over that year? Politics? The story starts as you'd expect. Accidents happen. Support. Returning to duty. What went wrong?
So they fire the guy, and promote someone else that can be relied on to say that the F-35 has no more defects than any other plane had at this point in the program, and we can trust the US military industrial complex to deliver the F-47 in a similar fashion.
At the same time, you send a message: eject when your plane is misbehaving and you'll end your career. Sure, there's a risk that someone won't eject when they should, but there's also a chance that you'll be able to cover up another malfunction when the pilot nurses the plane back to base.
Did Pizzo say anything disparaging about the F-35? I doubt it. But when you've got billions of dollars of revenue/potential embarrassment on the line, you don't take chances.
The F-35 is technically capable but even that is subject to export controls despite being purpose-built for export. A lot of European companies have a large stake in the success of the F-35 in its various versions because they are building it for European customers.
Not the typical mindset of someone wanting true superiority through military power. Makes you think twice.
The F35 is expensive, keeps the defense apparatus going, and ultimately gets paid for by other countries. F22 barely reached production, so F47 will be interesting.
The unfortunate reality, which the US is exploiting, is that Europe would struggle to produce an equivalent of the nerfed F-35, never mind one that hadn’t been nerfed. As a consequence, the US can sell nerfed F-35s all day. There aren’t many alternatives currently. 4.5 gen aircraft aren’t competitive in a serious conflict and everyone knows it. Even the US has to contend with that reality.
