Dungaree Justice

It has been correctly pointed out that there was never a real guided missile cruiser named the Montana. But there *could* have been. The actual CGN-42 was planned, but it was canceled before construction, and it was never assigned a name. If it had gotten a name, it would have been named for a state, and therefore could have been named Montana. The number CGN-42 was never used. Interestingly, there were two different battleships that were assigned the name Montana, but both of them were canceled, one during construction and the second before construction ever began. In the future there will be a ship in service with the name: the U.S.S Montana (SSN-794), a Virginia-class nuclear powered cruise-missile attack submarine, was laid down in May of 2018, construction was finished in February of 2021 and she was formally commissioned in the Navy on June 25, 2022.

While Harm and Mac investigate aboard the ship at sea, during two different interviews with two different enlisted men, the two sailors wear their ball caps while sitting at a table inside the wardroom. In the real world of the Navy, the sailors would or should know not to wear their covers while inside the wardroom, and, if they did so, by carelessness or otherwise, any officer present would have promptly reminded them to uncover. Wearing a cover inside a wardroom is a major mark of disrespect.
