1st, the majority of a navy is comprised of light, attack craft. Most of which could be comparible to fighters though my race does not classify them as such. Consider it my counting all the cheap cars on the road today as main battle tanks. 

2nd, I also didn't realize it was to be that detailed or a world limit. I was trying to leave it vague because of the loose NS for that exact reason.

3rd. battleship was supposed to be 800m in length, my bad lol. 830km is... beyond silly :D
