There is likely a USS Dreadnought looking rather more normal in terms of the hull colouring and with full legit markings being built with less weapons at the Utopia Plantia, or another facility.
Vengeance, unmarked and stealth toned, with large blister weapon sets, was going to look very 'off' to Scotty when he saw it.
The Dreadnought might even be further behind in construction with the Vengeance being given priority by Marcus. Everyone else would be expecting the class to role out months or even a year or more away.
Heck, we could see Dreadnought in the next movie.
