      At the beginning of the episode on the Battleship Wisconsin just before Operation Mainbrace, the senior officer mentions the Doomsday Clock and how they just advanced it to '2 minutes to midnight'. The Doomsday Clock was advanced September 1953 whereas Exercise Mainbrace was held September 1952. During the Operation, the clock was actually 3 minutes to midnight.
    • Quotes

      Dr. J. Allen Hynek: Do you even know how to pilot a submarine?

      Captain Michael Quinn: Had some basic training once.

      Dr. J. Allen Hynek: Yeah, well Mimi showed me how to make pancakes once, but I couldn't flip one now if you gave me a snow shovel.

    Jump the shark!
    The whole series has been quite watchable and the characters interesting but I found myself laughing out loud several times during this finale. It seemed to plumb the depths of an ocean of silliness and kind of ruined the series for me. I won't be holding my breath for a series 3 if it is as stupid as this cartoon episode.
