Forum:KB:Dreadnought-class heavy cruiser's crew?

Greetings, I have to raise the issue of weather the Dreadnought-class heavy cruiser really did have a crew of 16,000. I do not intend to speculate or provoke anyone to fanon, I just was a bit boggled to see a 600 meter long vessel with such a large crew. For example, the Valor-class Cruiser that was used by the Old Republic was only 500 meters long and only had a 2,400 man crew, and not to mention it was also a lot older than the Dreadnought-class heavy cruiser, and presumably had no slave rigging, so I wonder how a newer vessel that is only 100 meters longer, have a crew that more than quadruples that of an older, smaller vessel?
