Now of course ballistic and hypersonic missiles aren't everything, Iran's strategy still contains a TON of small missile attack boats designed to swarm US carriers.
The small boats have a mix of cheap multi-launch missile systems as well as high end anti-ship guided missiles(some can go 1000km!!).
They ALSO include anti-aircraft missiles so the can lay in wiat to interdict US aircraft on their way to Iran.
They have thousands of these water craft.
