Is is an issue for airborne drones. And signal jamming isn't the only concern. Long-range drones mostly rely on communications satellite relays for remote piloting. In a major conflict with a near-peer adversary, those satellites will be the first casualties.
That's one of the main reasons why the US military continues to spend heavily on manned tactical aircraft. The Air Force is actually decommissioning some MQ-9 and MQ-4 drones in order to free up funds for purchasing more 5th and 6th generation manned fighters. Airborne drones will continue to play a role, but until we make some major leaps in AI they will only be able to handle very limited missions.
