LOLS, you really are behind in fact checking.
Unions control what military contracts allow the military to create and repair organically. All US military forces are bound by contract as to what they can manufacture in their "depot level" repair facilities. Many of those facilities are quite capable of re-creating almost anything in an aircraft or vehicle (wheels and tracks). They are required to obtain parts from the manufacturers whether they could make the item in-house or not. Tens of thousands of items could be made in a repair shop rather than being ordered from the OEM and their suppliers.
That is the unions and the politicians. Organized labor guaranteeing their paychecks and politicians buying favor by nodding sagely and saying, "Sho' nuff!"
I know you're upset about the way things are going. Me, too. Lobbyists are just the beltway's infomercial. They're talking heads presenting facts about complex systems in sub-comic book form so that the politicians can understand it.
The military says we want this and the politicians work to make it not happen. Eventually, someone caves and the systems are created - usually as poor imitations of the original idea.
I have to run sorry
Unions? Unions are not the reason of why military spending is bloated in the US. We're talking about the problems of military contractors here, not teachers or police. Defense is not a heavily unionized industry at all. And the unionized workers that do exist in manufacturing have reduced size over the last 50 years while budgets have ballooned reliably.
You're also completely ignoring the massive role of lobbying and pork-barrel spending that occurs in the military industrial complex. It's pretty funny to fly through Dulles and see ads in the airport for missile systems, for example. These vendors love to use lobbying for tax development incentives and spread their programs across tons of states so it becomes politically unpopular to make any cuts. Is it smart for them to increase profit? Absolutely. Does it get us the best systems for our taxpayer money and benefit society? Absolutely not. So yes, I do consider these vendors responsible for their role in this mess or waste.
I get what you're saying about the DoD making bad choices in the requirements of the F-35, but it's laughable to act like Boeing, Raytheon, etc are just passive entities here. There is a closed ecosystem and the (one-way) revolving door between the military and contractors, and of course this leads to bloated and unnecessary programs. The DoD doesn't just draw up requirements out in a vacuum. The problem of bloated military spending isn't limited to this one plane and poor choices. We've had this problem for at least 50 years.
My original comment stands: great news for Boeing/Lockheed to sell more weapons for whatever is the replacement.
