I real like the Gorn fighter, pretty much what I though there fighter would look like assuming they had a standard fighter of their own.
I have a few concepts based on what I was able to get on ship designs in Federation and Empires.
Here is the Klingon Tug/Cargo ship
Here is the ZY Klingon fighter.
Here is the D5 war cruiser, Its the design based on the F&E game not the one in the show Enterprise, this one is built after the D7 and is supposed to be a faster lighter version, don't ask me why its a lower number maybe the D's are based on size not model number?
Finally here is the D6 Battle cruiser.
Like I said, Ronin I wouldn't have even gotten back to designing ships againn had your mod not inspired me to play the regular game again. If you want them their yours, if not I can totally understand you have plenty of ships here already.
