The Belgorod is a nuclear submarine, and its construction began in 2019. Its total length is 184 meters, and its displacement reaches 17,000 tons surfaced and 30,000 tons submerged. It is unclear whether there is an official record of her maximum speed, but it is known based on open source data that the Belgorod makes approximately 31 knots (56 km/h).
There are two principal goals of the Belgorod submarine: it carries nuclear unmanned underwater vehicles (UUVs) the Poseidon nuclear torpedoes. It can operate a small submarine submerged below the boat’s keel. In the event that Belgorod ever launches combat operations, it is capable of integrating a small nuclear sub capable of deep-sea diving in its hull.
This area also boasts other essential features, namely the possibility of carrying a large payload even when complemented by a second submarine at the rear, as well as the option for an independent nuclear power plant to be towed here.
Poseidon is an intercontinental nuclear-powered, undersea nuclear-armed autonomous torpedo. The Poseidon is a nuclear-powered torpedo 24 meters long, with a diameter of 2 meters, developed in Russia. Its underwater speed is 70 knots. For those unfamiliar with submarine speed, 70 knots equals 130 kilometres per hour. The torpedo is able to dive at 1 kilometre underwater. The conversion is unclear, and the explosive yield it carries can be up to 100 megatons.
The Poseidon nuclear torpedo at the Belgorod nuclear submarine has become especially dangerous because Russia has equipped it with a nuclear bomb. H. I. Sutton has published on his blog hisutton.com that the Poseidon torpedo is intended for use in a second strike, as one of the Russian nuclear deterrent’s parts, and its infection targets are coastal cities in East Asia, such as New York and Los Angeles.
“In this scenario, the lack of dependence on satellites and the fact that it literally passes under missile defences make it a slow but inevitable death. Critically, this is a diversification of Russia’s nuclear deterrent, not a replacement for submarine-launched missiles,” Sutton wrote.
