These "anti-drone" drone-launching turrets will be briefly successful, until opponents code trivial evasive maneuvers (randomly perturb velocity) into their cheap attack drones. Then some genius at Anduril will say "what if our 'drone' was really small and got catapulted really fast to overcome any meaningful evasive capabilities of its target" and then you have autonomous rifle turrets, effective against a wide variety of targets.
