You send in small assault shuttles that are designed to either burn through the hull and preserve the bits that you cut out, or just hack an airlock, and send your marines in. So you could say by convention, but really it's enlightened self interest that stops you from attacking ships directly with weapons. You already have a massive ice shield on the front of your ship to protect you from interstellar dust et al imagine what would happen if you struck a two tonne jaggedly edged piece of Hardashellium that used to be part of a destroyer's hull?

So given that you have the equivalent of shipping lanes, and that because space is big your ships have to travel really fast to get somewhere within a reasonable timeframe, the absolutely LAST thing you can afford is a bunch of debris right slap bang in the middle of your transit route.

The Hohmann Transfer windows for instance will commonly be used because they're efficient and fast, so provided your transit isn't time critical (and in many cases where it is) you'll just wait on Earth for the planets to be aligned properly to fly between them. There are going to be transit lines between major star systems and even between planets in a single solar system.īut wait! (I hear you say ) Planets are in orbits, so you're never going to use the same space to get between Earth and Mars, for instance.

Space is big but that doesn't mean that it's all going to get traversed evenly. Actually, it could be as simple as debris.
