Like crime said, but to nitpick, those three you cited are pretty useless for the actual invasion force. The real invasion forces are by land and sea, which America also has the largest amphibious assault fleet and military sea lift capability. But, let’s not kid ourselves about the actual challenges of invading a peer/near peer nation: amphibious landing ships have enormous radar cross sections (even the fancy San Antonio class) and would be easily sunk by anyone with antiship missile capabilities, especially with how close they actually have to be to the shore.
Using post-WWII invasions as a guide, the real key is to invade your neighbor or having an adjacent nation under your thumb to stage invasion forces in, as large scale amphibious operations are incredibly difficult to actually pull off.
Of course, if you invade Grenada then you could pull it off with just aircraft.
