The United States has a huge "Navy"

The U.S. military services are at war with each other to battle for shrinking funding. We hear, time and again, that the U.S. Navy does not have enough ships. That the U.S. Navy's goal of 300 ships is at high risk of being out of reach. Things are bad. How will we fight future wars?

What you have been told is not true.

The U.S. Army has another 50


And the USAF has 3 which move around munitions. These are chartered but useless without the job they were made for.

The United States Coast Guard? This is a valid count as this organisation has ships siphoned off supporting expeditionary warfare. It has about 244 cutters. Real "Littoral Combat Ships".

The United States has about 721 ships committed to National Security.

Many of these that are not traditional heavy hitters could be weaponized quickly to carry Tomahawk boxes or other similar missile-in-a box solutions.

The United States has a "Navy" scattered among many organisations doing national security work. When the DOD cries about not having enough ships to fight wars, don't believe them. And, lately most of those wars have been of the Operation:USELESS DIRT kind.
