i personally believe we are in a bad hole with our industrial base. there absolutely is a surge capacity problem right now in the supply chain, and there is a lot of focus right now in the DoW on the topic. the issue is multilayer and the comments about freedom's forge / WWII / willow run bomber plant run by ford reveal the problem and are damning about what we're doing about it.
Bill Knudsen (immigrant to Ford to president of GM) quit his job to serve the USG in 1939 as the director of production for the department of war. His realization was that you can't bend the supply curve fast enough simply by ordering. you have to build the capacity ahead of demand. Since we didn't have time to build capacity from scratch, the only available option was to convert existing commercial industrial capacity to wartime needs. there were four basic moves he used - pre-position factory construction and equipment orders out ~2 years before the demand needed them, use existing private capacity with deep manufacturing expertise as the production backbone, leave profit motive in place, and focus on supply networks to support final assembly.
the short version is we can't recreate what Knudsen and others did in 1939 to speedrun industrial capacity. there was a massive amount of latent civilian industrial output in the US that was leveraged into dual-use to support planes, ammunition, small arms, tank production. we don't have it. it's gone. we have lost our industrial depth in machine tools, tool and die making, castings, forgings, machining, electronics. it was cost optimized and outsourced.
and even if we did, if we look to freedom's forge as the (incredible) example of what can be done by leveraging the US economy we're talking two years to ramp.
the same supply chains that feed transformer manufacturing, gas turbine production, and all the inputs required to build data centers (steel, copper, etc) are dual use for war materiel. we can't meet the civilian AI surge even with effectively infinite demand pressure. what makes people think we can conjure up the ability to 10x or 100x our tomahawk production?
perhaps people don't know what goes into a tomahawk. you need semiconductor manufacturing, printed circuit boards and assembly, passive components (resistors, capacitors, inductors) for the electronics; you need composites for the bodies; castings and forgings for the titanium and other alloy structural components; more and different castings and forgings, as well as machining for the small turbofan gas turbine powering it; solid rocket boosters for the initial launch which themselves have supply chain exposure.
two thirds of the foundries (castings and forging suppliers) have closed in the US over the past fifty years. as recently as the 90s we had over 3000 domestic foundries, with less than half of that today. and along with them went the necessary input supply chains - pressure vessels and fabrication for their melters, vacuum systems, induction coils (specialty copper) and induction power supplies (electronics, specialty capacitors, specialty transformers), AND the know-how to design and build them. a lot of this stuff is just gone.
forging capacity is much the same - our really heavy forge capacity, like what's used to make aircraft bulkheads or gas turbine wheels (for power gen or jet engines) was made in the 50s. we literally do not have the ability to make the very heavy forges that we rely on today.
so - focusing on castings and forgings because i am "in" it - just take Knudsen's approach that it's two years to get the factory online, and now add two MORE years because that's how long the lead time is for the equipment that goes in it.
now do the same for the specialty heat treatment equipment, the coatings, the machine tools for finishing.
now think about the labor force that used to operate those machines - not only did we outsource and lay those off, not only did we double-bounce them out with layoffs in industry in 2008 and again in 2014-2019, we also have a massive contraction of available layer as a simple consequence of demographics. AND we didn't train labor - instead our best and brightest went into finance instead of engineering and manufacturing, and our skilled labor workforce was told to get silly college degrees. we lost a generation of manufacturing ability ON TOP.
AND we severely curtailed our defense contracting base after the cold war.
so yes - the shortage in the ability to manufacture so-called exquisite missile systems is very real. drones are no better (you cannot make a US manufactured input drone today, the supply chain doesn't exist). this is a MASSIVE concern for us, and the DoW and President Trump's administration broadly is taking this issue very seriously. the problem is they are (in my opinion) not learning the lessons Kudsen taught the USG in '39. you just can't bend the supply curve with orders. you HAVE to invest in capacity up front.
