I don't like questions like this because this can (and inevitably will) be misconstrued into defending an ideology I want nothing to do with. The "correct" answer is just objectively wrong. It was >relatively< few losses by any meaningful metric. Even saying that the Germans lost a certain percentage of their population doesn't mean anything (like absolute numbers) because where do we know when a percentage stops being "relatively few" and starts being "relatively many". We can only compare losses on the sides of the axis and the allies. And the axies, including Germany, suffered relatively few casualties compared to the allies.
You might want to read up about the war or either you're making very broad generalizations about what constitutes a single event.
Ask yourself a question. If battleships didn't exist, how would the war have changed? Now do the same for aircraft carriers.
In fact, battleships were so useless that the last American battleship was commissioned in 1944, retired in the 1950s, and there has never been another one since.
That said, I've modified the question to make it more obvious what the correct answer is.
