Here are some in-game shots. I took a cue from Legacy and did the name and ship number on a separate transparent TGA for easy swap-out.
The Flounder Class Transport was designed as a high-powered tug with engines designed to push heavy equipment between stellar bodies. At the start of the war, the transport was retrofit for defense purposes. The two large liquid fuel tanks where removed, and in there place, rail turrets where installed. Because the original design was not conceived with combat in mind, the clearance of the turrets is very limited. With fuel-less engines, the transports were used at stationary defense positions. The Flounders proved to be viable battle platforms. Many Flounders were retro fit once again, replacing their bulky dormant liquid fuel push engines with the newly introduced and conveniently sized micro fission drives. These new drives gave the transports the speed one might expect from a combat craft of its size.
