The nuclear submarines in the world are rarely seen, because most of the time they are cruising in the depths of the ocean, and only When maintenance and replenishment are needed, they will return to their exclusive ports to park and show off the water, and staff and nuclear submarines can be rescued. As Figure 1 shows, the submarine wrapped in steel looks like a The big shark, protruding from the back like a chimney-like thing, is its lift compartment, which is also a place where communications equipment is concentrated in nuclear submarines. When navigating in the sea, they occasionally show water and communicate with the outside world to update
