I have be boarded by Coast Guard while entering US territorial waters. They will line up all boats moving from Bahamas towards Florida and have them hold speed and direction. Then they push an inflatable boat onto the stern and board with about 6 people all armed with fully automatic rifles. Mostly, they look under the floor boards for drugs and make sure the registration and documents are correct. The Coast Guard does not mess around. When a $2,000,000,000 Ohio class submarine carrying ballistic missiles is most vulnerable leaving port moving towards water deep enough to dive in. The Coast Guard is tasked with keeping all potential threats away. The ships on the side would protect the submarine from RPG and similar attacks while the submarine is surfaced.
