And that's the issue we're running in to. The various widgets that go inside these weapons (maybe a simple actuating servo or a circuit board), widgets built in various warehouses in flyover USA by various salt-of-the-earth middle class Americans who drive Kias, deep fry turkeys on Thanksgiving, and live in modest suburban homes, are coming up against supply chain issues for the various widgets that they need to build their widgets.
Somewhere out there in flyover country is a middle-aged woman. She has a flower tattoo on her ankle. Her husband is overweight and has a goatee. He watches football on Sunday. The have a "thin blue line" flag hanging in their garage and a "FJB" bumper sticker on their car. We know these people. They're our friends and neighbors. She might post here!
And she works for the widget company in Shitsville, Kansas, making widgets for munitions. And they're making all they can but they can't make any more because the company in Indonesia the presses the circuit board they use is still following COVID regulations.
The Department of Defense is saying, "We need 250 of these a month!" And she's telling them, "We can give you 20. We can't give you any more. We don't have the supplies"
It’s defence, ... it’s everything.
Late model vehicle parts with all sorts of stockout and backorders, even for high volume parts.
And the vintage stuff, you can get the old flat tappet lifters and cams, but they are now unreliable junk with multiple failure modes due to manufacturing and material problems, as well as the oils.
