Also, How fast do you guys think would a fusion ship travel through a star system? The Astronomer Well, a few hundred kilometers per second for normal trips, can went up to thousands of kilometers per second if the two objects are really far apart and the ship has a lot of delta-v. Interesting, that makes KKVs a viable weapon against fusion warships, just fly in front of the ship and let it crash into you, at 300km/s you achieve 10t TNT/1kg dry mass.

My fleet just have to nudge in an instant to avoid your KKV. We have higher dv than yours so it shouldn't be a problem. Don't tell me your missiles are also fusion rockets. Irrelevant, what counts is acceleration, If I also have a fusion ship I can get a relative of zero, at that point you can't escape me anymore, my missiles have +10G Acceleration, fusion ships can't reach such high accelerations, my 131TW Fusion drive can only accelerate my ship to 1G (10% of c Dv and 1.3kT), it uses the firefly method of radiating most in space but it still needs to radiate 800GW of waste heat to not melt. my missiles can also thrust for a short amount of time to get in your path again, if the missile is in front of you how do you want to escape? Most fusion ships don't even have gimbals. The answer to later question is: Not in this case.

That is assuming any reasonable fraction of it is absorbed. Typically it takes a fair bit of material to absorb high energy gamma rays... Sorry to tell you, but I excluded Gamma-rays from my calculations for that exact reason. Oh? Now i am curious: What fraction of the annihilation energy did you assume would be absorbed (or what was your reference source)? Presumably some assumption on the fraction of energy present in the charged particles produced?

Presumably some assumption on the fraction of energy present in the charged particles produced? Yes, 66,4% percent of the antiproton energy is emitted as charged particles.
