I am thinking that a good design for realistic capital ships will have four fuel tanks, three armor (one per section), three hangers for drones, two major batteries for beam weapons, two habitats, one tertiary batteries for missiles, one tactical comm/sensor array, one control room, one fusion reactor, one fusion drive, and one hanger for shuttles. At TL10, that gives a delta-v of 240 mps, which should be sufficient for most capital ships. A SM+12 capital ship will have 900 SM+4 drones, 900 40cm missiles with 10 megaton antimatter warheads, and 30 SM+6 shuttles.

The beam weapons are probably improved 30 GJ lasers with a total RoF of 40 on a 3-minute turn, dealing 6d×10 (2) burning d-damage up to a range of 10,000 miles and 6d×5 (2) burning d-damage at a range of 30,000 miles, allowing for orbital bombardment from GSO of missiles and lasers. The soft targets get the lasers and hard targets get the antimatter missiles. A pure spaceship of terror will exchange the missiles for 2,700 40cm bombs with 10 megaton antimatter warheads, which ends up not even doubling the payload cost, which it would drop from GSO.
