  • Trivia

    • The submarine's depth gauge is labeled improperly; the dial lists the units as "METEPC", or the word "METERS" transliterated into Cyrillic characters, rather than translated into Russian.  The Russian word for "meters" is "метров," or "metrov" when transliterated into Roman characters.

    • When the submarine surfaces, breaking the ice cover, the diving hydroplanes on the sail are in the horizontal position. All submarines with hydroplanes on the sail rotate it to the vertical position before breaking the ice cover. The edge of the hydroplanes are reinforced and angled for this purpose.

    • The bridge console shows high definition flat-screen plasma displays. In the early 1980s, the equipment used would be CRT displays.

    • When the sub is resting on the ridge at 700 meters (2300 feet) depth, the missiles can not be launched. The maximum launch depth for the Delta III/IV submarines are 55 meters (180 feet).

    • Trivia: The HADS (Hostile Action Defense System) is mentioned for the first time in the series since the 1968 serial "The Krotons."
