This makes the colonizer a legitimate military target, too.

Of we're talking about an 'every now and then' option, a redundant streamlined deflector might be enough and you can get the boxy, massive look-and-feel beloved by the movies. That also helps with modular options (see below). Talking about those laser rings makes me thing of a roughly cylindrical shape, possibly with little control surfaces from the lifting body.

Two ships with one neutrino com each can talk to each other. Several ships with two coms each can form a 'ring', any unit can reach any other unit through relays. But the loss of any two units breaks the ring. Three or four are needed for a redundant net.

Three are the mimimum to let two accurate ones vote the faulty one out. You can't afford to take them down for maintenance if you have only three. And astronomical LLTVs are technically sensors rather than nav, but they should be part of your navigation suite. Last but not least, IFFs would be nice. > Bridge with roomy crew stations for captain, pilot, engineer, sensor-op, > gunner. Crew stations have crashweb, gravweb.

Moving at 'realistic' in-system velocities: A one-cf rock would really ruin your day. Say it moves at 50 mps relative velocity and you want to detect it 10 seconds out. That means -33 speed/range, -2 size, +6 for radar in vacuum. Since detection should be fairly certain, you need 2,000 or 3,000 miles nominal sensor range. A 0.1-cf rock would still be catastrophic for lower-TL craft, and finding it requires 20,000 miles nominal range. Moving at 'cinematic' in-system velocities: Say you are moving at 300,000 mps. The ship will be more agile, so call it two seconds warning. -52 speed/range, -2 size, no +6 because I'm not assuming EM systems. On the plus side, the operator will have a pretty good neural net, getting the most out of the available raw data. Maybe 3,000,000 miles (16 ls) nominal range. Detecting 0.01-cf rocks would be nice, too, for 30 lightminutes range, but at some point you have to leave dust for the deflectors.
