Besides carrying cars the carrier drone can also deliver 4000 or maybe even 6000 pound bombs.
Two or three carrier drones appear able to work together to lift longer and heavier payloads like 12000 or 18000 pound bombs or a truck or a shipping container.
The US daisy cutter bomb weighs about 15,000 pounds. It is an anti-personnel weapon and an intimidation weapon because of its very large lethal radius (variously reported as 300 to 900 feet/100 to 300 meters) combined with a visible flash and audible sound at long distances. It is one of the largest conventional weapons ever to be used, outweighed only by a few earth quake bombs, thermobaric bombs, and demolition (bunker buster) bombs.

It’s small enough that you can stick it on a trailer a drive it down a single lane road, making transportation relatively easy.
