The US had Predator drones and other large drones with sidewinder missiles and other missiles for quite a while.
Smaller and cheaper quadcopter drones have had machine guns and grenade launchers mounted on them with stabilization systems.
Drone Swarms launched
In Jan 2017, US F-18 fighter jets releasing a swarm of Perdix micro-UAV swarm during a Naval Air Systems Command’s demonstration held at China Lake, California. Measured at just six inches, the micro drones are capable of confusing enemy defenses and blocking radar signals. The drones are not pre-programmed synchronized individuals, but a collective organism, sharing one distributed brain for decision-making and adapting to each other like swarms in nature. Consisted of 103 Perdix micro drones, this is the largest-ever test for the cutting-edge swarm technology.
Antidrone net launchers
Radiowave and other jamming systems are being developed to disable drone electronics.
Israel has a high end anti drone jamming system. The US air force purchased one for $15 million.
There are also systems for launching small anti-drone missiles.
