The US is still the comparative military powerhouse of the planet in every way but raw troop count. A nation can launch a nuke from a carrier, a silo, a submarine, a mobile platform. Those aren't used right now, obviously. Carrier groups are the current state-of-the-art for regional modern warfare. They aren't for invasion, but are useful for activity suppression and area control (derived from air superiority). The US has 11 nuclear powered aircraft carriers with 2 more on the way. The next largest fleet is China with 2 + 3 lesser ships they call carriers (but they are more like troop carriers, battleships, depending on how you want to classify them) with 2 more aircraft carriers on the way.
