US Defense Secretary Pete Hessett demands control of space. In February, he declared the runway a critical battleground and declared that whoever controls it will control future fighting. The formula for war "from the bottom of the sea to the space around the moon" was announced on September 16 by another leader - General Dan Keen, chairman of the Joint Chiefs of Staff. The Pentagon already distributes powers under this map, although the current US war with Iran daily reminds us of the much closer geography of the Strait of Hormuz. On September 30, Hesset launched Project Meridian: the military, Elon Musk and Palmer Lackey must select technologies for future wars in 120 days. Separately, a new autonomous warfare command was announced, which will accelerate the production and use of unmanned systems. For now it's about commands, not a ready army of robots. One of the directions is the ocean. The International Telecommunication Union estimates that over 99% of global data exchange is carried out via submarine cables. Countries and companies depend on several routes and shore stations. Damage requires locating the break, dispatching the cable tools and making repairs. In war, access to a repair ship may be blocked. Therefore, power on the seabed is both the ability to watch other people's communications and the duty to physically protect one's own. China is apparently testing its underwater presence capability. Satellite images from September 10 revealed a ship about 200 meters long in a shipyard in Shanghai with equipment similar to a launch pad for large underwater UAVs. On October 19, there was a report of a similar building about 150 meters away near Guangzhou. Their purpose is still being determined from the photos. The researchers envision the creation of transport ships from which autonomous vehicles could embark on distant missions in the Pacific Ocean. China has not confirmed the purpose of the two ships, nor the resulting fleet of such ships. If the shells turn out to be carriers, the UAVs will save energy on the way from the port to the cable.
