>>6047835why not both? We don't need to limit ourselves to only a singular type of drone after all. Specialized APS drones could be used as well against missile targets.
>>6047837and yeah, these drones would likely not be in use unless necessary. And I don't really expect that we would NEED a lot of drones to see positive results since they are meant to "follow" the enemy. With the simple thrusters we can give them, they would be able to fly along the path of where enemy projectiles would hit from and as soon as one is damaged, another flies over and takes its place. The best example I could give of how they might potentially act is how the fighters in Enders game were used as reactive shields against enemy fire in consecutive layers. These would just be a lot dumber and well...armored.
Pic related, Enders game scene I'm thinking about concerning this.
