Terran War Ships

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

Try three rotating elements, plus the barell also rotating. Elements one and three must have the same length. Element 2 should rotate opposite to element 1 and element 3 should rotate the same direction as element 2, with the barell rotating the opposite. Setup --- then it will turn \_/, then I_I, X and -

Emm, actually two rotating elements of the same length are enough, set the direction to the opposite and the speed of the second to twice that of the first.

@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
