I have done a race called United federation and made star trek ships and classes with within than canon,these include:

Akira,Enterprise,Ambassader,Galaxy,Steamrunner,Danube,Constellation,Shuttlecraft amongst others!

I have also created a Klingon race,Romulan star empire,and recently Cardassian Union I plan to do Dominion/Jem Hadar and Breen in the near future.

Asto the warship Classes I have been building ships that both look and named like naval space ships with Classes such as Frigate,cruiser,heavycruiser,Destroyer,Battleship,Dreadnought and actual ship class names as rowanoak,sheffield,coventry etc with gun/missile turrets that swivel around! (on the Y axis) I would have liked to get the effect of the guns actually recoiling but you cant have everything! lol

@Echelion - I have a Federation too with Constitution, Ambassador, Galaxy, Sovereign classes amongst others like Royal Navy's Admiral Class - Hood, Rodney and Invincible class - Inflexible, Indomitable, Indefatigable and a Bellerophon class including Dreadnaught of course. Also created me own Audacious class with Bold, Courageous and Daring. I tried to build a Romulan Warbird Next Gen style  alas it didn't look so great haha

@Antibor - thanks Swiveling turrets would be totally sweet!- gon give it a shot
