Hmmm, why does this bs about SSD turn into SSDD everytime. According to Starwars.com:
http://www.starwars.com/databank/starship/superstardestroyer/index.html) its 19,000m. Not 11, 17.5, 12, but 19. When in doubt, check starwars.com, they have tech sheets on all things starwars. Like Duece says, "Thats one big b@tch."

lol, first of all, the Executor was first listed as 8000 meters long (West End Games' mistake, repeated on StarWars.com). Then it was changed to 8000 miles, which equals 12.800 meters (StarWars.com's mistake). Now they've done some more propper measurements of the model used in the movies and have landed on 19.000 meters. But I fear they've done a small oversight in not taking into account that the bridge tower on star destroyers built by Kuat since the Imperator came out has the same measurements on all later models. Once you know that, and the executor models lenght and tower measurements, it's easy to calculate its size.
So in closing, when in doubt, by all means check StarWars.com (
http://www.starwars.com), but then cross referance that with Star Wars Technical Commentaries (

So excuse me if I don't put my full trust in everything that is said on StarWars.com. :p
