I'd expect a military design to be built around defense which would mean limited points of entry with an easy to defend/hard to access form outside point of exit should the entrance be overwhelmed. Perhaps there may be a cevilianized version along at some point with multiple?
The civilian MISC Starfarer with only one entry point is confusing as it effects utility, however the military Starfarer Gemini makes sense to limit the points of vulnerability, except for the entry point is the width of a road.
