I shook my head. "We thought about that. It would have to be busters, or something that could be directed. And even so, you’d have to launch weeks before the encounter, and you’d have to plan it to intercept the enemy at the right place and the right time. Chances of getting it right are too low. Plus they’ll see the approach from a light-hour out with SUDDAR and they just have to dodge. The busters would have a ridiculous tau and wouldn’t be able to react quickly enough. If we forget about relativistic speeds and just stick to our normal ramming, they won’t even feel it. Or they’ll just zap ship-busters a couple dozen at a time with those big zappers."
