Massive Space Yards

[Aussie Gamer]

The ship yards would be at a higher tech than the normal ship based space yards.
The 400 ton one requires tech 2 Yards up to the massive yard of 2400 ton one which requires space yards 4, yep an inceased level, and stations 3. So by then one would hope that the empire is very large and able to deal with the resource drain.
The idea is really from Star Trek movie when you saw the little ships leaving the HUGE station.
Hope this helps the idea along.
