. Yesterday i viewed the TOS episode "The Enterprise Incident" and in this episode, i noticed that the Romulans have a cruiser class Klingon D7. I am surprised that there is none in the Dafedz's database and yet these cruisers are part of TOS.

. How many construction ships the empires they must possess? 1 or 2 ? (Only the Federation possess 2 ships and not other empires)

The other empires will be getting more construction ships - or at least upgrades of the existing models - at a later date. The construction ships are the newest class of ships in the game, so they've not had the amount of development time that the other ship classes have had. I sent Dafedz a PM a few weeks ago about further developing the Construction ships but he hasn't yet replied.

I would like to go back and fix up some of the construction ships. Right now I am trying to get my head around the program Blender to us in model development. This takes some getting use to but it should help the game.

I am thinking about some 2D images of the ship building a station but need to ask Mike if that might be used in the main interface.
