Why they think it will be different this time I don't know.
The contractors lie about capability and cost because they want to win the contract. The DoD accepts these lies because it wants shiny new toys. Congress goes along with it as long there's pork involved. No-one learns anything because there's no incentive to avoid corrupt behaviour. The MICC at its finest.
Reality intervenes and the project goes overbudget. Production gets cut, yet it doesn't really save any money. The project continues through several cycles of the death spiral until it is either cancelled or delivers a product. And we end up with the congress critters getting their pork, contractors getting their piles of money, DoD getting their shiny new toys, along with promotions for anyone who didn't end up holding the bag. The troops end up with nothing or a handful of gold-plated weapons with less capability than they were promised. Oh, and the taxpayer gets screwed, but that's the usual outcome.
Consider: you grab a movie from the Pirate bay, and seed parts of it to torrent peers in 15 other countries. Is it fair to be convicted in each country separately?
Don't give the RIAA and MPAA execs ideas. Imagine receiving multiple copies of their standard legal shakedown letters, each threatening a copyright lawsuit in a different jurisdiction where you may have been infringing.
You will have many recoverable tape errors.
