I have made them, although you can create your own groups using my (Export) Tie ships. Once you download the ship, open it in the designer, hold shift and select all of the parts and Save as new part will be able to be selected. Click that and save the name you want wish. This will save it to your universal parts in the parts list.

From there you can place as many as you like, although it will take into count the parts used in the group so less is always better. I have the bomber, tie fighter and Interceptor as exportable (Save as Group) ships.

I may add more but am avoiding the group ships for now until I see if they can fit in with the ship style under construction.

Love those squadron formations^^ Is there an easy way to copy paste additional ships in those fromations? Would like to get TIE Interceptor, Bomber and Defender squadrons and the likes.
