I'm having trouble reconciling this comment with reports that US stockpiles are already being depleted by the Iran war. At this point the US weapons production seems relatively specialized and inefficient, not "huge scale." Someone more informed care to weigh in?
I’m probably not more informed, but it seems to me that it can be both. The rate of expenditure in a medium-sized war will far outstrip peacetime production needs. Even if you’re arming half the planet’s militaries, your peacetime production rate will be much smaller than what’s being used now, even if you’re building a lot by non-wartime standards.
Raytheon is about half the size of Pepsico, with about the same profit margin.
The supposed "Military Industrial Complex" that Ike warned about died years later, and the end of the Cold War buried what little remained. The F-35 is basically the only big military construction project we've had in a very long time, and it comes at a few hundred airframes per year.
In WW2, we were producing 10k+ rather advanced airframes every single year. In each category.
The company that designed and built the M1 Abrams Tank doesn't really exist anymore for example. We, like Russia, might not really have a capability of building 4000 hulls in a short timeframe, which is table stakes if we are actually concerned about a war with China. We were able to do these things back in WW2 because we, through central planning (not a free market), reorganized like 1/20th of the economy into building war assets. FDR decreed that we build 120k Shermans. We eventually managed 50k.
A lot of the supposed "graft" and pork of the defense industry is about giving it a lot of leeway just to stick around. Once you lose domain knowledge it's gone forever, you have to expend considerable resources to rebuild and recollect it. No, documentation doesn't count. Reading all of our notes hasn't fixed the fact that Russia and China can't build the exceptional jet engines we can.
