They aren’t that much larger than us at 395 ships. They sometimes claim closer to 800, but that is including non-combatant auxiliary ships and 19 replenishment ships. Of the combatants 150 are missle boats which range in size but max at about 140 ft (smaller than a frigate).
We are at 295, including 67 logistics and fleet support ships, and have another 50 in mothball and 91 in National Defense Reserve. In addition, our airpower is massively superior at 11 vs 3 carriers.
Thanks!
