Not a single person here said anything about nuclear contamination

Poseidon is expensive complicated extravaganza when dealing with surface ships

Missiles are more than sufficient, if you want guaranteed results just add nuclear warhead

64 nuclear armed Tsirkon... at least the world would end with a beautifull firework . I doubt Mars life had such plaisure when they ended.

They are controlled via the signals in the wire, but not powered. The electrical power required to drive a torpedo at high speeds thru water is considerable, and there is no way to conduct sufficient current through the long thin wire that are spooled out behind a torpedo in flight.

Measure of power: why does Russia need the world's longest submarine
The nuclear submarine Belgorod is one of the most ambitious shipbuilding projects in the country
Dmitry Boltenkov, Alexey Ramm
13 February 2021

Special-purpose submarine "Belgorod" is preparing to go to sea for the first time. Sources in the military department told Izvestia that the world's longest submarine has a high degree of factory readiness. Preliminary tests of units and mechanisms have shown their serviceability and technical reliability. The nuclear-powered submarine is over 180 meters long. This is 11 meters longer than that of the largest nuclear submarine Typhoon, and 12 meters longer than that of the American Ohio-class submarine. The domestic submarine is one of the most ambitious projects in Russian shipbuilding. But how much does the Navy need it today? After all, the Navy, albeit with a delay, began to receive the Yasen multipurpose nuclear submarines and the Borey strategic missile carriers. The military historian Dmitry Boltenkov dealt with the issue especially for Izvestia.

The history of the giant

The nuclear-powered ship "Belgorod" was created to combat enemy surface groupings. It was supposed to carry 20 Granit cruise missiles on board. It was planned that the submarine will become the 14th in the family of boats of Project 949 and 949A.

Although the nuclear submarine was officially laid down after the collapse of the Soviet Union, on July 24, 1992, in fact, its construction began earlier. That is why Belgorod can be considered the last submarine of the departed superpower. In 1997, the construction of the submarine and two more of its "sisterships" was stopped due to the difficult economic situation. Subsequently, the metal structures of the two ships laid down after the "Belgorod" went to the creation of submarine missile cruisers of the "Borey" type.

After the tragedy with the nuclear submarine "Kursk" in August 2000, the question of completing the "Belgorod" to replace the deceased submarine was considered for some time. However, in the end, they decided to build a nuclear-powered ship for other purposes. The process of developing new types of weapons is slow. The systems that Vladimir Putin told the Federal Assembly about their appearance in 2018 in his message to the Federal Assembly have been created for a long time. And one can understand why in the early 2000s it was decided to use the Belgorod as a carrier of a variety of promising underwater systems, including combat ones.

On December 20, 2012, the construction of the nuclear submarine resumed, but already according to the new project 09852. On April 23, 2019, the submarine was taken out of the boathouse for completion afloat and conducting various tests. The transfer of the submarine to the Russian Navy is scheduled for 2021.

During the work, the boat underwent major changes. In particular, its hull was increased by 30 m due to the insertion of new compartments. Thus, "Belgorod" became the longest submarine in the world. New compartments were needed to accommodate a variety of underwater vehicles, as well as to release them into the marine environment and receive them back.

Tsunami underwater

The nuclear submarine Belgorod will become the first regular carrier of a new strategic deterrent weapon - the Poseidon super torpedo. In fact, it is a Doomsday weapon. With its help, a retaliatory nuclear strike can be delivered on the territory of a potential adversary if he attacks first.

The highest population density and the largest cities and industrial centers are located near the coastline. A nuclear explosion of enormous power near the enemy's territory, in addition to the damaging factors themselves, will also cause a tsunami.

It should be noted that the Poseidon system is already being tested on the Sarov submarine, but it can also be used autonomously. The construction of the Belgorod submarine is proceeding at a faster pace, especially against the background of delays in the schedules of other nuclear submarines, in particular, the attack submarine Kazan.

And other robots

In addition to Poseidon, Russia has created or is creating many more underwater robotic systems, in particular the autonomous unmanned vehicle Harpsichord-2R-PM. It is capable of conducting research and prospecting work at a depth of up to 6 thousand meters. For example, it can find sensors of underwater observation systems located at the bottom of the sea. Curiously, in the publicly available images of Belgorod there is always a hangar for this product.

For testing anti-submarine operations and, most importantly, for camouflaging and protecting submarines in Russia, the "Surrogate" apparatus was created. It is a submarine simulator with reproduction of its acoustic and magnetic fields. Such a technique will divert the enemy's attention to false targets during the conduct of hostilities. It can be assumed that the Belgorod will also carry it on board.

"Harmony" and "Losharik"

The development of the Harmony underwater observation system is underway in Russia. This is a complex of quickly deployed target detection sensors on the seabed. In peacetime, the system will be able to monitor areas of mining, primarily oil and gas. In particular, "Harmony" will be able to find in time foreign objects that can damage the production facilities.

In wartime, "Harmony" will be deployed to create the so-called defensive bastions. These are sea areas completely isolated for the enemy, where strategic submarine cruisers and boats with Poseidon drones on board will be on duty.

In addition, Belgorod is the carrier of the so-called nuclear deep-water stations, such as AS-31 Losharik. These miniature boats are designed for a wide range of underwater technical operations at great depths (according to some data, up to 6 thousand meters). In particular, for searching for lost military property, detecting or installing various underwater sensors, connecting or destroying communication cables.

The above systems are far from the only ones that are created in the interests of the Russian Navy. They are simply the most famous. On the development and adoption of attack submarines equipped with missiles and torpedoes, information has not yet appeared. However, this does not mean that they are not being developed.

The cruiser "Belgorod" has a wide range of underwater vehicles and robots as a carrier. The use of a variety of systems in the course of combat operations will ensure control over vast sea areas and will minimize the loss of warships and submarines. It will also give the possibility of guaranteed destruction of both the enemy's combat assets and his territory. Therefore, we can safely say that the commissioning of "Belgorod" as a whole brings the concept of "naval war" to a new level.

They put weapons on a "research" vessel. That's weired.

We saw that such vessels conducts dangerous missions and adding two micro nuk power plants on board isn't making it safe.

They should have used a borei for that IMO.

Hahahaha... research sub.... almost as much a joke as deep submergence rescue vessel...

Would be like having a sun rescue vessel that can fly to the outer layers of the sun to rescue astronauts that might get caught there...

The thing is that no one who goes below about 400m can be rescued... and the depths the deep submergence rescue vessels operate at no one would be alive to rescue...

Research Sub and DSRV are cover terms for special ops cable cutters and cable buggers... (ie people who put bugs on cables not people who bugger cables...)

Interesting size comparison between the two torpedoes

Major new refresh of the #Russian Navy Belgorod #Submarine article http://hisutton.com/Belgorod-Class-Submarine.html


Not quite in time for #SubSunday.
The internal arrangement to accommodate the ginormous Poseidon weapons is still speculative but we are getting there.

MOSCOW, March 2. / TASS /. Tests of the special-purpose nuclear submarine (SPN) "Belgorod" of project 09852 will begin in May. This was reported to TASS by a source in the military-industrial complex.

"The state tests of Belgorod will begin in May after the White Sea breaks open from ice. They are in no way tied to the tests of the deep-sea nuclear Poseidon," the agency's interlocutor said.

TASS does not have a comment from the Sevmash press service (the enterprise where Belgorod is being built is part of the United Shipbuilding Corporation) on this score.

The submarine SPN "Belgorod" was launched on April 23, 2019. Initially, it was planned to transfer it to the fleet in 2020. According to reports, this did not happen due to the non-completion of the test program, including those related to the coronavirus pandemic.

The Russian Navy’s latest ‘Special Mission’ submarine, K-329 Belgorod, has put to sea for the first time. Open source intelligence seen by Naval News indicates that the submarine left Severodvinsk on June 25 2021. This represents the start of sea trials which are critical to the delivery of the new boat to the Russian Navy.

Above link contains a picture and a video of Belgorod making her transit out to White Sea.

It looks beautiful. I wonder if Belgotod will serve in the Russian navy or in GUGI. In addition to carrying the Poseidons, it has many other interesting missions.

It serves in the rank of GUGI. There is even a batch for it.

Fresh photos of Belgorod, two very large Poseidon tube visible, could be more below:

Its remarkable how similar the Belgorod is to the 955A like Kynaz Vladimir.  Belgorod has no outward similarily to the 949A, and if we didn't have prior knowledge I suspect we would never guess her lineage (except for her rudder and towed sonar array arrangement).  It looks like they have repurposed her pressure hulls, reactor, propulsion and major equipment, and repacked them in a completely new outer casing, forwards weapon compartment, sail and mothership interface (and no doubt some other goodies).  No wonder the rework took so long.  

Project 09851 is also based probably on the 955 project. I wonder what the situation with project 09853 looks like.Probably one under construction.
Belgorod actually looks quite different than the 949A. This is a completely new submarine. It probably has quite new equipment, a new reactor and power plant from the 955A submarine. So it is a completely new 4th generation submarine new class.

Satellite images from Maxar taken earlier this month and provided to USNI News confirm that a special purpose ship, Akademik Aleksandrov, is using the facility. And the vessel appears to have a Poseidon round, or related surrogate load, aboard.

The facility is on the Northern shore of the Northern Dvina River on the edge White Sea. Work on the new quay started in 2018 and was substantially completed in 2020. Akademik Aleksandrov has been observed there in July and August. There is also a large building that was recently built adjacent to the new quay and may also be related to Poseidon operations. This specific quay appears directly connected to Poseidon testing activities, according to the imagery.
