A drone is a reusable platform, unlike a one-shot missile

Evidence

But those old flying torpedoes may be considered more as the ancestors of cruise missiles than as those of present-day drones. The essential difference lies in the fact that while the former can be used only once, the latter are reusable. The drone is not a projectile, but a projectile-carrying machine. — Grégoire Chamayou, A Theory of the Drone, 147
