David Weber, start with On Baslisk Station, then slowly fall in love with military Sci-Fi.
Sheilds would be doable, as they are invulnerable top and bottom (works in a 2d universe), and vunerable on the sides. The sidewalls would get pretty heavy, as there would be no front or back. Hmm, bet Cruisers "cross the T" easier than Battleships.
You'd also have to make huge fighters/small frigates to do the LAC's, and I can;t wait to see what you do with the SD(P)'s.
