I am a sciencefiction writer who specializes in military science fiction. I have a question dealing with the affects of high speed targeting. Take two ships travelling on a recropical course. Each is seeking to target the other with weapons that can accelerate to close to C. Make one going at 0.65C, the other moving at 0.15C. Assuming both have targeting systems and weapons that are equally capable. Would the the ship going at 0.75 C will be harder to target? Thanks!
