Strazhe [Guardian] BOSS

The Rubin Central Design Bureau (CDB) (part of the United Shipbuilding Corporation) has developed the first Russian submersible patrol ship intended for foreign customers. This was reported to TASS on 12 April 2021 in the press service of the Central Design Bureau. "Rubin" represents the first modification of a submersible patrol ship, combining the advantages of a submarine and a surface patrol ship. The project is intended for foreign customers and was named "Guard" (Border and Offshore Submersible Sentry, BOSS).

"The cost of patrol ships on the world market is relatively low, which makes them acceptable for countries with a small budget. Operation pays off by preventing poaching and other economic offenses. Ships of this type are multifunctional, can be used for protection, as well as a rescue or research vessel", explained at the Rubin Central Design Bureau. "When choosing equipment, we focused as much as possible on existing samples, which are mass-produced and commercially justified, including equipment for surface ships and aircraft."

The submerged position gives the ship two advantages at once: the ability to conduct covert surveillance of intruders (and successfully intercept them) and escape from adverse weather conditions without interrupting patrolling. A submersible ship can be used as a classic submarine for reconnaissance and other tasks. A "diving" patrol ship will have a greater ability to explore the shelf than a similar surface ship. It can also serve as a low-cost training tool to prepare crews and infrastructure for the future procurement of classic submarines.

In its architecture and contours, the ship resembles Project 613 [WHISKEY] submarines, the most massive series of the Soviet submarine fleet, which was in great demand by foreign customers. The main characteristics are also similar, the displacement is about 1000 tons, the total length is 60-70 meters, depending on the configuration, the crew is up to 42 people, including the inspection team. At the request of the customer, the ship can be equipped with torpedo armament, small guided missiles and small caliber artillery mounts. Provides for the placement of boats for inspection teams, as well as an unmanned aerial vehicle with an autonomy of 2-3 hours, released without leaving people on deck.

It can also serve as an inexpensive training tool for preparing crews and infrastructure for future purchase of classic submarines. boats ", - added in the press service.

It is worth noting that the idea of ??a hybrid vessel that can perform tasks both underwater and on the surface is not new. As experts note, even at the dawn of the development of the submarine fleet, this concept was forcedly applied when creating submarines, because due to the level of technology development, then submarines could submerge only for a short time and most of the trip was carried out on the surface. This circumstance forced engineers to resort to appropriate technical solutions. So, the French boat Narval, which was put into service in 1900, used a steam engine for movement on the surface, and electric motors for underwater operation, which were recharged from a steam installation.

The hybrid ships include the British submarine X1 and the French Surcouf, which were in service with the two countries in the first half of the twentieth century. In addition to torpedo tubes, these ships were armed with large-caliber artillery pieces, which were used on the surface. With the development of technology, in particular the emergence of nuclear power plants, which made it possible to increase the time spent under water, such hybrid types of ships are finally a thing of the past. However, engineers kept coming back to this idea.

For example, in the USSR in the 1950s and 1960s, the development of a submersible missile ship of project 1231 was carried out. According to the idea of ??the designers, such ships were supposed to combine the stealth of a submarine and the firepower of a surface warship. However, the project was never implemented. According to experts, the scope of the machine has not been sufficiently developed. In addition, it had a rather complex design, which, among other things, increased its cost, while it did not have significant advantages over other types of equipment. So, the ships of the project 1231 did not differ in high speed, had a short cruising range and were vulnerable to enemy aircraft.

Nevertheless, the development of two-medium ships is underway today. In particular, in France, the shipbuilding concern DCNS is working on the creation of the diving warship SMX-25. The ship's design was first presented to the public at Euronaval 2010. The length of the SMX-25 is 109 m. The hull shape is adapted for high speeds - about 38 knots (just over 70 km / h) on the surface. As planned, the SMX-25 should arrive at its destination at high speed, and then go under the water and secretly strike at the enemy.

According to analysts, at one time the use of hybrid ships was a necessary measure. "During the Second World War, submarines could not stay under water for a long time - they had to surface to recharge the batteries, so they put serious weapons on them, for example, large-caliber cannons, which allowed them to inflict damage on warships," a military expert explained in an interview with RT Yuri Knutov.

According to him, today this concept can be used, but for other purposes. The hybrid idea has significant merit. For example, if a ship is on the surface and needs to be saved, it can go under water by diving. In addition, due to the possibility of deploying missile weapons, this ship can use the surprise factor and hit the target first, the analyst said.

But retired colonel Viktor Litovkin believes that the hybrid concept has its drawbacks. "The idea of ??a hybrid ship has not yet found mass application, because any such multi-profile ships are always worse in performance than specialized ones: they cannot fully perform the tasks of either surface or submarine vehicles," the expert said in a conversation with RT.

Analysts believed that too few details are known about the Sentinel project so far to talk about its prospects. At the same time, they did not rule out that if this project is successful, such vessels may not only be supplied abroad, but also used in Russia. We need to see how this project will be implemented, what technologies Russian designers will use there. At the same time, I do not exclude that in the future the "Guard" may also be of interest to the Russian Navy, "concluded Viktor Litovkin.

CDB "Rubin" is one of the world leaders in the creation of nuclear and non-nuclear submarines and the largest design bureau of marine technology in Russia.
