Couldn't they just send a boat/plane/balloon/zepplin with a charger on it out launch the drones from there. The would come back when low on power and recharge in waves. It took me 30 seconds to think of this so I am sure there are a lot of better ideas out there already.

That's not a new idea. In wartime any vessel or aircraft approaching within range to launch missiles or drones will be attacked.
