> How do drones get around the issue of communications jamming?
For one, by making it harder to jam in the first place. Starlink with its extremely directional antennas is a good example - an opponent would need an equally massive fleet of satellites or high-altitude ECM planes to jam it, and the latter ones can easily be targeted by anti-radar rockets.
This is why the US government has been pushing insane amounts of money into SpaceX... Starlink is the future of interconnected wars.
