The Khabarovsk nuclear submarine strengthened the Russian Navy. It carries an underwater UAV with a Poseidon nuclear power plant, capable of hitting ship formations and coastal infrastructure, and its explosion could cause a wave up to 200 meters high, said military expert Dandykin. The submarine will soon enter service in the Russian Navy. "The Khabarovsk submarine is the first production submarine as a carrier for Poseidon. It is likely that there will be two more such submarines, and this will already be a very serious signal to a possible enemy. It is said that Poseidon is already at the stage of completing experiments. It's a unique underwater UAV, not a torpedo. It can go far, with a large nuclear engine, far, with a large nuclear engine," a military expert.
