Oh, while I'm on the subject, another diVersionary naming tactic I use is to make sure each of my various stellar manipulation ships is a different class even if they have identical components. I don't do that for ship types with much more numerous members, since it makes for a _lot_ more work, but stellar manip ships are rare an expensive. I don't want one unlucky combat to let my enemies know which of my ships have sunbusters or warp-openers and which are just storm-clearers.
Alternately (there's _always_ an alternately), the ship classes "Nova1", "Nova3" and "Nova6" could have actual sun-destroying components whereas the classes "Nova2", "Nova4" and "Nova5" are actually just repair-and-resupply ships. Try to avoid having them get into combat, to keep your enemy from discovering that you're using this tactic. After the first system-bombing, he won't know which task forces are major kamikaze threats and which aren't - hopefully, he'll think they _all_ are.
One can always rename a ship, but one can't always easily change their class designation.
Confusion to the enemy!
