During the space jump scene, one of Marcus' crew members alerts him that an airlock had been open on Deck 13 of the Vengeance, which as we know was due to Scotty opening it for Kirk and Khan to enter the ship. Is it just me or is that an awfully low numbered deck to be that low on such a supposedly massive ship? The airlock in question is shown to be in the mid to lower secondary hull of the Vengeance. On the Enterprise D that area would be somewhere around Deck 30. For Deck 15 to be that low on the Vengeance that would make her just about the size of Voyager. I'm not sure what it is with Trek writers not being able to get deck numbers right, as Generations and First Contact both couldn't seem to get it right.
