I use a different naming scheme. While i considered using something similar to keep things tidy, i just don't like it. I use abbrevations such as AF for Attack Fighter, which is obviously an offensive combat oriented fighter. Or FRCr for Fast-Response Cruiser, which puts emphasis on engines and speed but cuts back on the armor and a little on the weapons.
I also add a numerical value to denote the version of the ship. For example; AF-101 is pretty much a fighter with a single laser

That while a AFr-303 would be the third version of an attack frigate.
- The first number denotes hull size (1 = tiny, 2 = small, 3 = medium, etc)
- The second number denotes the type of vessel ( 0 = Attack vessel, 1 = Fast-Response vessel, 2 = Defensive vessel, etc)
- The third number denotes the version of a ship (Mk. I/II/III/IV/etc)
It can be a bit confusing, but i've used this naming scheme since the beginning of my strategy game addiction

Once you got the naming scheme in your head, it's extremely easy to pick them out of a list.
