I could see a hybrid approach, where a bunch of drones are loaded into a mothership, possibly a repurposed bomber with a bomb bay full of drones. That gives you local control of the swarm, and a way to deliver them over much longer range.
Come on, let's be serious. What makes your idea distinct from existing weapon systems? Instead of making up new names for old things just look up what is serving the same purpose as your idea. "Drones" are just guided bombs or missiles. "Motherships" are just fighter jets or bombers.
CARRIER HAS ARRIVED
Headline: America switches to Protoss, rushes Fleet Beacon.
You've pretty much described the F-35 doctrine that the US is developing. The only major difference is that an aircraft carrier or some other ship holds the drones before launch, which makes sense as the you already need the carrier to launch the flight controller craft (the F-35)
