It was an early battle following Pearl Harbor, and it was Japan’s entire carrier fleet vs US’ entire carrier fleet, and the grand totals were something like 4 carriers vs 3 carriers.
At the end of the battle they mention that by the end of the war the US was completing multiple carriers per month, and they were just orders of magnitude ahead of every other country when it came to manufacturing power and steel production. Japans only hope was finishing the us Navy early on at Pearl Harbor and midway but once the US ramped up production the US never lost their military lead (arguably they still have it). Meanwhile at the start of WWII the US wasn’t even top 10 militarily. It’s astounding how much changed in those 5 years.
