I still think it is a 4/1 joke, the submarine to receive it is the USS Montana...and the entire article reads like the Hunt for Red October. Even the last sentence is "Either way, Montana will remain unseen", imo a tribute on Capt Borodin's last words "I would have liked to have seen Montana".

NavalNews has a history of April Fools articles.
