“One scuttles one’s own ship. The enemy doesn’t scuttle you — they sink you.”
Well, if we won the war, technically, they were surrendered, and were “ours”. In the not too distant past, it was fairly common for the victors to actually re-flag and utilize the spoils of war. These days, of course, these goodies generally can’t be integrated into the victor’s command/control/support systems and are destroyed or possibly sold/given to others.
I do know that after the war, a lot of people in the Navy came back with some Very Cool Stuff taken from ships about to be scrapped (like deck-mounted binoculars, which were awe-inspiring in their optical quality).
That's because we have, by world standards, an unlimited procurement budget. For decades, the Israelis have reused Soviet equipment captured from the Arabs. North Vietnam kept RVN equipment captured after Saigon's collapse in operation for a couple of decades.
