The largest of the drones would be ocean going robot submarines, capable of conducting surveillance, launching weapons, and perhaps even carrying small raiding parties. The robot submarines would be small enough to be transported by cargo aircraft, and could be maintained from, and carried on Australian made high speed transport ships.
The smaller drones would be the size of mini, lightweight, and full size torpedos. Some drones would operate as smart mines, then attack as torpedos. Others would provide aerial surveillance, and attack. These drones could be launched from submarines, ships, and aircraft.
