Not necessarily. Most of these drone types trade off speed and kinetics for the endurance. To get the same payload you would need a bigger bus. To counter that APS and laser systems would easily defeat them and swarms would necessitate a deployment system to move them on station that is going to attract attention. If you try for smaller drones but more numbers the payload drops now it’s useless vs armor and shorter range.I have a feeling that loitering munition will replace traditional ATGMs in the future. You basically get the same payload in the same package but far greater loitering time, range, and potentially the ability to swarm. Best of all, you can recover the munition if you fail to engage the target.
