Yeah... even with it's atrophied industrial muscles, you don't out-build the US and Europe combined. Worst case scenario comes when the US and Europe actually start committing to wartime production. We're still not doing that. Almost everything so far has been from old stocks and supplies.

During World War II, the US sent 1,911 locomotives, and 11,225 railcars to the Soviet Union under the lend-lease program, just as an example of the scale of production we have achieved in the past. The US has many many many flaws, but we've demonstrated a history of being able to out-build everyone once we're committed to it: https://en.wikipedia.org/wiki/Lend-Lease

Another phenomenal one was that the US shipyards put out an average of one Liberty Ship every TWO days (every other day....) from 1941 to 1945. https://en.wikipedia.org/wiki/Liberty_ship

Hell, we made 270+ destroyers during WWII. It's a mind bending quantity of ships produced: https://destroyerhistory.org/fletcherclass/

We can't afford healthcare, our cities are rotting out, and our schools are being undermined by small minded bigots, but we can sure as hell build weapons. If there's a will to fight, and NATO is committed to supplying you, you'll never lack for hardware.
