You're making a different argument.

You're saying we need to retain manufacturing capability and expertise. I agree.

I'm saying we need to stop being bled dry by private weapons manufacturers on cost plus contracts who are rewarded, by definition, by making the system as expensive as possible.

If we were truly interested in having an effective military, we would bring production in-house and focus on standardized vehicles and weapons systems with standardized interchangeable parts on production lines that can be scaled up if necessary.
