One famous example is Corning which mostly does kitchenware and then also huge military contracts for military equipment. But then of course every single US company takes on military contracts from Ford making engines to Singer making sewing machines and guidance systems during cold war lol

So OP is absolutely right. American companies will dip into everything that makes money which is really not a problem tbh and that’s how capitalism is intended to function just a bit funny given that one company makes kitchenware and bullet proof glass for mil vehicles.
