Ok, well, I may go ahead and use standard federation textures, with a Marine Corps twist of course.
I also had a little problem, and came up with what I feel is a novel solution. Ok, first problem is this....standard versus pulse phasers. I contend that regular "strip type" phasers are much more accurate, as it is possible to rotate the emmiters on all axis's to direct the phaser stream where you want it to go. This system, by definitiion, lowers total power output capability. Pulse phasers, on the other hand, put out a much more powerful energy level, but of course have limited aiming capability....the cannon is moved slightly to give the weapon a slight firing arc, but generally the weapon's arc is very narrow, so the entire ship has to be aimed to fire the weapon.
Now, this ship has both types of phasers, the Defiant "pulse" style and the standard strip style, but the system is comprised mostly of pulse emitters/cannon. I felt like there was some way to better aim the cannons, and it came to me....why not move the entire cannon, ala battleship style? After all, DS9 had rotating photon torpedo launchers, so why not a rotating phased cannon? I set it up to work just like a battleship cannon battery, with a moving cannon that can rotate 360 degrees, and the cannon itself can rotate up 90 degrees.
Ok, so the idea is afoot, but there is another problem...the design of the ship does not give me many places to place the cannons to avoid obstructions by the hull. The dorsal hull wasn't a problem...I used the sensor pod as the platform for the dorsal cannon battery. But the ventral hull is another story. The centerline of the hull, in the deflector pod, is inset by design...meaning there is a trench that runs for to midships from the deflector array. If I place a cannon in the trench, its arc will be limited to a very narrow firing trench fore, dorsal and aft. So i decided to make a platform for the cannon to sit on, pushing it out of the trench. The only obstruction is the warp engines, but that cant be helped.
I have posted pics of each of the batteries. I also posted quick picks of the wing cannons, nose cannons, and the aft torpedo launcher. Let me know what you think of this idea.
