Are kinetic weapons realistic in (future) real world space combat
I love the hard Sci Fi aspects and real physics of the game but one doubt that is always at the back of my head:
Are we really going to slug metal in space combat?
* Based on the game setting: the ships are engaging one another across hundreds of kilometers at the relative speed of dozens of Km/s. The ships are no more than a few hundred meters long. the projectiles' trajectories thus need to be extremely precise;
* Within those hundred of seconds, even a slight change of the ships flight path will allow it to dodge the projectile (I understand hence there is bracket fire, but still the brackets are filled with enormous amount of space)
* Any kinetic defense will be able to push the projectiles off it's precise trajectory. A 40mm autocannon doesn't need to destroy a 800KG warhead as in the combat gameplay, it just need to carry enough kinetic energy to push the slug off by a few hundredth of a degree
Are these assumptions correct? Or are kinétic warfare a viable/ actually discussed path in real word? I remember it was referenced in Liu Cixin's three body trilogy
