Get Chinese XLUUV!
"[The] PLA Navy (Chinese Navy) has a new kind of submarine. We are told: China is hoping huge, new, smart unmanned submarines will help give its naval fleet an edge in crucial waterways like the South China Sea and the western Pacific. These subs, dubbed extra-large unmanned underwater vehicles or XLUUVs, are much bigger than the current crop of underwater vehicles - large enough to dock as conventional submarines and to carry significant weaponry and other equipment. Their artificial intelligence will help them operate undersea, not only to avoid natural phenomena, but to detect and identify friendly or hostile ships and make navigational decisions to avoid them. The XLUUVs are also designed to complete tasks without needing to seek input during the course of a mission. The intention is for the subs to depart, complete their missions and return without needing guidance."
Be not afraid however. The U.S. Navy also has already in the water or at least in the developmental stage and on the drawing boards a XLUVV! This is Orca. As in the killer whale.
We are so lucky!
