> What keeps them from changing or trying out new ways of designing/building? Is it entrenched interests that resist any changes? If someone had been honest and told Congress "Oh, the F-35 will cost $1 trillon dollars" they would never have approved it. The military does this so that they can claim something will be cheap. Then over the next 5 to 10 years they increase the cost astronomically, step by step, because Congress will look bad canceling the program and getting nothing for all the billions they spent so far. There's no one resisting the change. If I gave you unlimited money, but all you had to do is take it $100 at a time, you'd do it too. The problem is that Congress refuses to keep the DoD accountable.
