I’ve seen a few articles now that US fighter jets have kill switches in them, so the US could just render them useless for anyone they’ve sold them to.
Is this true? It sounds insane to me, I’ve always assumed that countries that buy these jets have full control over them. It’s a gaping hole in your defence if you don’t.
The game changer will be swarm capable drones.
A few smart drones can be used to guide a swarm of cheaper drones on target. Additional sensor drones can feed back info to improve this.
Currently, defensive systems can cope with a drone attack. However, if you have 20 coming in from all directions, in perfect coordination, they will be overwhelmed. You don’t even need all of them to be armed, just a couple, protected by the rest.
Current drone usage is akin to the first tanks in WWI. The WWII equivalent will be terrifying.
