Ok, due to popular request I have added a medium range, medium power dual disruptor cannon on the port and starboard sensor cooling towers. This works actually, because this would be one of the reasons this design was so successful compared to the D series...better weapon coverage.
So the port and starboard weapon holes are covered....though not by a super powerful weapon. The weapons are reasonably strong, quick fire and quick charge but range is not extreme, so the enemy still has to be fairly close.
A side note...not sure how the C-9 or E-7 was hardpointed, and if it was hardpointed different than what I am about to disclose, that is noones fault but my own. There are blisters on the hull of the E-7, believe there are ones on the C-9 (I will have to look) and definitely ones on the E-6. The green glowing blisters are for close range defense...they are low power, short range distruptor points, but the special thing about them is that they have a 180 degree firing arc.
They are designed mainly to intercept torpedoes and the like, but can be used for close range fire when needed, though they are not strong by any means.
Just wanted to point that out. There are enough blisters to completely cover the hull with close-range protection.
