Writer is an idiot, but then again, that's the style of those on that site. Tomorrow, another writer on that site will come out saying that the F35 is the greatest thing since sliced bread. But I digress. Politics killed the F22 in favor of other "projects"
F35 costs are still coming down as efficiencies are wrung out.
Make no mistake, I'm not defending Lockheed, they really deserve a black eye for their ineptitude, incompetence and mismanagement in the early years of the program. But the F35 packs a crap ton of technology into it that no other aircraft has seen or will see for quite some time, so those complexities take some time to sort out.
Sadly, I really believe you're going to see more and more incompetence in programs in the future thanks to companies promoting "wonder kids" into management roles. I'm seeing it right now on one and if they are an indicator, the future is quite bleak. Glad that I'm just a few years off from retirement and won't have to endure them and their ilk much longer.
