Criticism of F35 is unfair. As a military procurement programme it has exceeded all reasonable expectations, at least in terms of meeting its objective.
I think the problem lies with our understandinmg of the objective....
Some of you seem to think it is to bring into service a multi role stealth fighter than can take on any opposition, or something on those lines.
However, you're wrong. the objective is to be a sink hole for money. Objective met with 100% success.
If, at the end of the project, you get a useful bit of kit..... Well, consider that a bonus.
