In the US, what Lockheed, Boeing and Northrop do is far more insidious and harder to overcome though. They don't sell to the public at large. You never saw that Boeing commercial with the two little kids talking about the f-35 and the f-18 on American TV.
What they do is hire a bunch of ex-military guys, who come with a degree of built-in gravitas. Then they sell their program with all of its faster-than-light technology to some major who more likely than not may not even have an engineering degree. The next thing you know that major is all lathered up, and has sold the program to his Colonel and his general. all of a sudden, the glossy brochure becomes a valid verified military absolute must have need. and while the warfighters are getting themselves in a frenzy about how many Americans will die if we don't have this glossy brochure technology, no one with an actual science degree has actually looked at or verified that any of the bull crap is even feasible. So when the system is delivered with the equivalent of dozens of engines missing in terms of cost of capability, no one notices because the airplane flies around makes lots of noise and drops bombs. But it sure as heck ain't what anyone was expecting at the beginning of the process.
And with all due respect, Nue, Lockheed isn't lying as much now as they did in the early days because there is such a substantive body of work, both good and bad to support or deny any ridiculous claims that they make. And they were put under tremendous pressure during the Bogdan days to get their house in order.
To me, it's just a matter of Saab being markedly worse at lying than the other companies. So they forgot to include an engine is part of the FlyAway cost? Kids stuff compared to the amount of capability that was whittled out of the f-35 program between 2008 and 2016. The other point is a lot of that capability that disappeared from the program while costs increased--no one will ever know about it because it was all Green door stuff in the first place. So yeah, forgetting to include something as obvious as an engine is pretty boneheaded. But certainly dollar-wise no worse than any of the shenanigans Lockheed, or Boeing, or Northrop have pulled on their various programs through the years. Nobody knew that the f-35 was supposed to have a banana trash powered flux capacitor, so when it dropped out of the program, only a few people even cared, and they were the program office people who are most vested in the success of the program at that point.
Have we also already forgotten that the super hornet was supposed to be a miner upgrade compared to a whole new aircraft development?
So again, one company may be worse at the fine art of lying, but their lies are certainly no better or worse than the others.
