Russian research submarine of giant dimensions

The gigantic scientific research submarine, created in Russia, will move under the ice, mapping the seabed relief with two huge wing-like wings. This submarine will help Moscow to explore hard-to-reach areas of the Arctic, so that in the future it could go on to develop its untouched natural resources.

The Arctic scientific research submarine was designed in the famous KB "Rubin", which also created the world's largest nuclear missile carriers of the project 941 "Shark". The vessel will weigh 13 280 tons and is likely to become the largest civilian research submarine in history, since its length will be 134 meters. It will develop the maximum speed of the 12,6 node, and in its crew will be 40 person.

The most striking detail of the boat is two sets of hydroacoustic receivers similar to the wings. The presence of such wings gives the boat some fantastic view. "Wings" will be removed inside the hull as a blade of a folding knife. They are designed to receive signals from the sonar located in the hull of the vessel. This will allow the Arctic research submarine to form an image of the seabed in all directions when moving under water at a low speed of three knots.

Analyst G. Sutton, who created a website on Covert Shores submarines and wrote the book of the same name, tells the following about the Arctic submarine: "Analysis of the layout presented by the design bureau shows that the length of the wing-like structure is approaching 50 meters, and thus, The wingspan is equal to 100 meters. This is much more than any aircraft built today. " Sutton made a drawing, from which it becomes clear that the wingspan of the boat will be even greater than that of the airbus A380.

However, Sutton is confident that the wings will not have any hydrodynamic purpose. "Wings are unlikely to be used to create a lift, like an airplane. This will be inefficient, as you will have to constantly use the steering wheels to keep the boat at a given depth. In addition, they will create noise interference, which makes sonar less effective. "

The submarine is built especially for navigation under Arctic ice, but because of the huge size it will sometimes be difficult to control it. "There are many places in the Arctic Ocean where this boat will not pass, because it has too long wings, and it will touch them with ice columns descending down from the ice surface," Sutton explains. "They can descend hundreds of meters and even reach the bottom."

Since the boat is civil, it will not have any weapons. It will house uninhabited underwater vehicles (drones), and it can sink to a depth of up to 400 meters.

Russia is determined to secure the right to extract minerals and energy resources in the Arctic, in those areas that will become more accessible due to global warming, which reduces the area of ​​pack ice. Moscow declared bold territorial claims in the Arctic Ocean to areas extending far beyond the 200-mile economic zone. But many other countries aspire to them, and some of them even want to own the North Pole. Sutton notes that in 2007, Russia, using a mini-submarine, installed its flag on the seabed in the North Pole region at a depth of over four thousand meters.
