why not just detach the warhead and save the drone?
replies(6):
And the result is much less accurate, and the warhead is smaller. Instead of actively flying the warhead as close to the target as possible, the drone now needs to calculate the optimal detachment point and hope the warhead ends up at the right place for an intercept. This detachment point needs to be at least several seconds before intercept to give the drone enough time to get out of the blast radius, so if the target is actively evading, any hope of hitting it is basically zero.
As long as the drone is cheap enough, this is the superior solution for the widest range of viable targets.
Maybe if you are going up against lots of really simple drones with zero evasion capabilities and no armour, it might make sense to to even simpler and swap the warhead module out for a what is essentially a large single-shot shotgun, but that's going to have significantly less power.
