I'm sure they do, otherwise it would be too cruel.
However, even if they don't, they are still in one of the most beautiful places on earth. Does anyone know if navy vessels have a large environmental on the waters? Can you, for example, go snorkeling just a short distance away from the naval port?
Pretty sure you'll get arrested for espionage if you snorkel nearby .
Having snorkelled in Hawaii last year, all I've got to say is that there are great locations all around the island. Oahu (where Pearl Harbor is) is actually not that great compared to, say, Maui, since it is more developed. I saw a lot of dead corals there (people kept on treading on them).
