Re: Dreadnought-Class Production Line (Spoilers?)
Until I actually read the thread, I had thought that the discussion here was about how long the Vengeance project had been in the works. I suspect that its creation pre-dates the discovery of the Botany Bay by a considerable timespan.
That makes perfect sense. The unfreezing of Khan probably slowed the design/construction process down slightly because they used his Eugenics War experience to upgrade the weapons systems and other tech. But the Vengeance was going to be created no matter what. What we see in the film is just a more dangerous version than originally designed by Section 31.
