Chrysler was given task of taking the hand-fit 40mm Bofors
anti-aircraft gun and mass producing it for WWII. They gave each
division a main part and used over 1,000 sub-contractors for the
small
parts. Drawings were translated from Swedish so the shopmen could
read them. I imagine the entire process took months so our ships
could
be better protected for the war. One aircraft carrier shot down
32
Japanese planes in under half an hour with these things. Thinking
back to my yout, I called these "pom-pom guns".

I think the "pom pom" was a different, British, gun.
Often remembered in its multiple-barrel form.

Yeah, same Bofors, built by the Brits in quad format.

The original Pom Pom was a late 1800's Maxim machine gun scaled up to
37mm. When it was replaced with a different design of 40mm gun the
name stayed, so it can be considered generic for an automatic cannon.
