I'd argue your first point directly contradicts your second point.
I don't want the military failing hard and failing fast. Make it work, make it work well, and then don't mess with it.
The B-52s are a shining example of this.
Behold:
"The unexpectedly long career is due in part to a rugged design that has allowed the B-52 to go nearly anywhere and drop nearly anything the Pentagon desires, including both atomic bombs and leaflets. But it is also due to the decidedly underwhelming jets put forth to take its place."
"“There have been a series of attempts to build a better intercontinental bomber, and they have consistently failed,” said Owen Coté, a professor of security studies at the Massachusetts Institute of Technology. “Turns out whenever we try to improve on the B-52, we run into problems, so we still have the B-52.”"
"I don't want the military failing hard and failing fast. Make it work, make it work well, and then don't mess with it."
This presumes the mission, terrain, and enemy remains static, which has really never been the case. What worked in WW2 isn't often going to be effective for today's problems.
Sure there are jobs that are nearly eternal, from which we should pick proven designs, doctrines. But especially in wartime, a "fail fast, fail cheap, and learn quickly" is exactly what I would want in a military to complement the decades of bureaucratic planning that preceded in peacetime.
