Sci Fi Ship Class GuideI.L. Jackson's Guide to Ship ClassesAs anyone who has glanced at my gallery knows, I am a star ship fan(atic). I love designing my own starships and I know others do too. But, I've noticed that a lot of artists do not have a good idea of ship classes, what they do (traditionally) and their uses, particularly in a fleet. So, here is a guide to ship classes as they have been used traditionally and how they would likely be used in a sci-fi setting.Capital ShipsThis is the one a LOT of people get wrong. A Capital ship is an anchor ship for a fleet, meaning that fleets are built around the capabilities of the capital ships. Just about every other ship in the fleet has some job relating to the capital ships, whether it be defending or tending or supplying that ship.Capital ships tend to be the largest warships in the fleet. Capital ships also virtually NEVER operate alone. A great example is (original universe and original series) U.S.S. Enterprise from Star Trek. It was a heavy cruiser.
