If you don't like this, then stick to your fantasy.but don't mix the two. Space Battleship Yamato, Battlestar Galactica, Star Wars, Star Trek, Babylon 5, any goddamn sci-fi show is *BULL***** as far as hard realism and number crunching goes, especially since they use magitech like forcefields or just engines (like on the Vipers) that are beyond what is physically possible. So anything "realistic" will have to be based on those figures. Those are the drives with enough specific impulse to make interplanetary missions viable. Between the two are micro- to deci-gee direct nuclear drives, the big brother of NERVA. You've got miligee nuclear-electric drives (with Giga-Watts of power! ~ a current nuclear power-plant can do about 500-1000 MW!) on the low, pretty sure end and full-g torch drives (with Terra-Watts! of power) on the far power that also does some magic hand-waving about how a magnetic nozzle operates. This is strictly plausible mid future tech. This isn't about far future tech with anti-matter or some gravity/quantum quirk that would allow a "reactionless" drive. For mili-gee drives even ballistic kinetics are an issue, however for torch-drives they have so much power that only light-speed and missile weapons with a similar drive would be. Especially the spherical war-cows stuff, as they debate kinetics-vs-lasers to kinetics-vs-lasers-vs-missiles to death in a myriad scenarious. For sanity's sake: read the damn stuff people with engineering and science degrees have posted above. Even atomic warheads would need to get a lot closer (couple of kilometers) to do the deed with sheer gamma radiation pressure. ![]() Finally just put a bomb-pumped laser on the missile as a warhead and you've got one deadly weapon that can do a "proximity kill" in space from a light-second away. Meanwhile the missile can be designed with a lower delta-v requirement and it won't have squishy humans inside with their bulky and heavy life support system. ![]() The same physical laws apply to both and the ship's also weighted down by a mission section and the delta-v requirement (huge fuel to mass ratio) to carry out its mission. Seriously missiles can accelerate just as well as a ship, and there's no reason why they couldn't intercept a ship. Wave based? What are you smoking gent, I want some! If you meant light-speed, then.
