DefianceIndustries has recently decided to take a stab at rendering an odd prototype in the CIC archives. The ship depicted in these black & white photos and blurry images is commonly seen as the precursor to the TCS Midway. It has many of the megacarrier's design elements built in, although the final version smooths out some of the hard lines, centralizes the bridge tower and separates/stretches out the left and right hull sections. Here are some of the concept shots:
And DI's take is below. It turns out Cybot actually mocked up the ship at one point too. Clearly our home carriers have made a lasting impression on the minds of WC fans! For reference, we've also included the final TCS Midway from Prophecy as well as the TCS Port Broughton from Wing Commander Arena.
