Robotic Quasi-Submersible Attack Vessel Fire Sequencing Strategy

Interestingly enough, the software programs which control our UAVs when they lose contact with the satellite are quite simple. Keeping the aircraft straight and level, and maintaining the necessary flight characteristics are not that complicated at all. In fact, if the military loses contact with one of our drones, the robotic aircraft simply turns around and flies home after so many minutes having lost contact. Meanwhile, it flies straight and level, and continues on its mission more or less.
Now then, with this in mind I have another topic of interest, perhaps one even more important to the future safety of our nation, allies, and overseas assets. We will need to create more robotic quasi-submersible naval attack vessels. These units will use a hunt and destroy method. And there will be many times when they are not in contact with the satellites due to heavy storms or cloud cover, or ocean currents which temporarily push them under the water too far, making it difficult for a signal to get through.
Therefore, these vessels will need special firing sequence strategies. Again, just as with the UAVs it could be a very simple program. Even if an enemy ship turns off all of its power, or an enemy submarine goes silent, the quasi-robotic submersible will be able to use a firing sequence, just as the strategy used in World War II with the U.S. Navy destroyer, as they used depth charges in a grid defense pattern to find in sink enemy German U-boats, which today could be a simple program - ever play Battleship, the strategy board game?
I would recommend that the guns fire in the following sequences; four - two - two - four - repeat within the grid of the last known position of the enemy target. This will either shake the captain of the other ship into firing back, or trying to evade the area. As soon as the enemy vessel fires upon the submersible, it will have given away its position. If it starts up its engines or tries to evade, it will also be detected. Once the detection has occurred, the submersible can contact all the other submersibles in the area with the exact location, and direction of travel. Swarm warfare strategies will then ensue.
Even if the submersible is taken out of action and hit by the enemy, that new information of its location will be given to all the other robotic vessels, any enemy doesn't dare repeat that trick. Having large numbers of these vessels around, our robotic units can detect enemy ships, submarines, sea mines, and perhaps even aircraft. We need to be thinking here, because other nations are with their naval forces. After all, things are heating up in the South China Sea, Sea of Japan, and the Straits of Taiwan.
There have been skirmishes off the coast of the Philippines, and we all know the challenges in the area of the Straits of Hormuz, as well as off the coast of South Korea. Also think of the pirate activities originating in Somalia. Our defense industry could sell thousands of these units to all of our allies protecting their coastal waters and interests.
