I really like the engineering hull on this so far, It's dramatically better than the original. Also have you put any thought into the Ventral armaments?
Personally I believe that two phaser arrays, that run the somewhat of the length of the saucer, similar to that of an Intrepid class, would suit her well. And another set of launchers added to the aft edge of the engineering hull would help to give the ship some aft coverage.
My reasoning behind the suggested addition of the ventral arrays, is because I do not believe that a ship of that size would be able to defend itself properly with only pulse phaser weaponry. Even the Defiant had several standard, but small, arrays. With a ship of this size there's a lot more ground to cover, and a lot more blind spots than there would be on a ship like the Defiant.
In regards to the size of the Achilles, Memory Beta, which has the entire history of the Achilles taken from the Dominion wars game, states that the vessel is slightly smaller than the Sovereign, at approximately 612 Meters in length. So you're in the ball park with it's size.
I can't wait to see more of the small details that i'm sure you will add to the ship. I was curious as how you were going to handle that bridge module until I saw it. It came out very well. You could probably make it even longer with that extra space you have behind it.
I am curious as to what that flat rectangular structure is behind the bridge though. Will that be the bussard housing for the auxiliary warp drive?
Keep up the good work Wiley.
