Regarding the Khazad-dum...

Quoted

Main belt does not fully cover magazines and engineering spaces

Your coverage is 65% while a minumum of 87% is needed.

Regarding the Eorlingas...

Reminds me of my Giga Mogami sim. :D

...I always forget to check that! I need to write a list of "All the things to remember to look at before pronouncing a design complete." Bah. ;(

Heh, and you will still sometimes forget things even after creating many designs.

Don't feel to bad the first design i submitted i forgot to put some form of propulsion in. Then I went back and edited it later. Nice designs, the Eorlingas is a pretty big cruiser though even for a large one.

Does it follow Rohirrim naming conventions?

Hmmm. I've not planned that far ahead for Rohan (Navalism). I've gotten up to 1922 designs, and those are subject to technology and political factors. (This was designed some time ago as a "logical" design progression following an American pattern of twins than triples followed by twins of the next model of gun size up.)
