Seabed scout: "Vladimir Kozitsky" will help "Varshavyanka" to sink NATO destroyers
Hydrographic vessels and boats, which are in service with the Russian Navy, are difficult to rank among warships - neither guns, nor missiles and torpedoes, but their importance cannot be underestimated, like any other auxiliary vessels of the fleet. Cruisers, destroyers, and even submarines, and even more so without a hydrograph - as without hands, or rather without eyes that scan the seabed and clearly give out depths and obstacles.
Now the Black Sea Fleet has received a new large hydrographic boat (BGK) "Vladimir Kozitsky", on which the St. Andrew's flag was solemnly raised in the Novorossiysk naval base.
Just a week earlier, the Black Sea Fleet received a similar BGK Boris Slobodnik. This testifies to the increased demand for naval hydrographs, including in the Black Sea, which, it would seem, has been studied along and across, but there are still secrets, "black holes" on the seabed here. And this is primarily due to the activity of Russian diesel-electric submarines of the Varshavyanka project in the Black Sea Fleet, which need a detailed location in order to know where to dive and where to swim.
Actually, initially, hydrographic vessels and boats as part of the Soviet Navy were required for research in the seas and oceans in order to ensure the navigation of submarines in remote areas of the World Ocean. As part of the same Black Sea Fleet, the 422nd division of hydrographic vessels was created (similar units also existed in other fleets), which explored not only the near water area. For example, the hydrographic vessel "Stvor" (built in 1983, Polish shipyard in Gdansk), still in service, with a displacement of 2500 tons, has an autonomy of 40 days and is capable of making a sea voyage with a range of up to 8000 nautical miles.
On board such a vessel there is everything you need to conduct hydrographic research, which allows you to make route measurements and depth measurements, measure the temperature of the water in different layers (such information is also necessary for the commander of the submarine). There are also two hydrographic survey boats, which are launched for more detailed studies, for example, of the reef zone, when the vessel itself is at anchor. In addition to "Stvor" in the composition of the hydrographic service of the Black Sea Fleet, there was one more similar one - "Donuzlav". Now the detachment of hydrographers was replenished with "Boris Slobodnik" and "Vladimir Kozitsky".
By the way, both Vladimir Nikolaevich Kozitsky and Slobodnik Boris Davidovich , whose names were given to new large hydrographic boats, were participants in the Great Patriotic War, have military awards and, as it is easy to assume, headed the Hydrographic Service of the Black Sea Fleet in different years. So BGK got decent names.
The new hydrographic boats of Project 23040 G are, of course, difficult to rank among the ships of the far sea zone. The Russian Navy has already received five such "crooks" for submarines, which left the stocks of the shipyard "Nizhegorodsky Teplokhod".
BGK were built according to the project 23040 - an emergency rescue boat, which is also called a raid diving boat. Its displacement is about 118 tons and it is not capable of going on a large ocean wave. Nevertheless, the boat found application not only in the Black Sea and Baltic fleets and the Caspian flotilla, but also in the "serious" Northern and Pacific fleets. In the hydrographic version, it is also present in the entire Russian Navy. It's all about the "stuffing" of the hydrograph.
BGK project 23040 G is intended for high-precision area survey of the daytime relief and survey of navigation hazards at depths of up to 400 meters and bottom relief survey at depths of up to 2000 meters. By the way, the maximum depth of the Black Sea is 2 210 meters, and the maximum diving depth for submarines of the Varshavyanka project, for which the hydrographs will “feel” the bottom, is 300 meters (240 is considered optimal).
BGK is designed to service all types of floating warning signs (FWS), setting / filming FWS up to 1.7 tons and length up to 6.5 meters. It can be used to deliver personnel, food, spare parts and repair teams to coastal aids to navigation equipment, navigation and hydrographic support of rescue and search operations. The boat is also capable of carrying out pilotage and liquidation of submarines and large-tonnage ships at bases and on approaches to them.
In recent years, the hydrographic fleet of the Russian Navy has been both updated and replenished with new ships. True, most of the small class. In addition to the mentioned BGK project 23040 G "Boris Slobodnik" and "Vladimir Kozitsky", which are now part of the Black Sea Fleet, two small hydrographic vessels of project 19910, large hydrographic boats of project 19929, large hydrographic boats of project 23370 G. of New Ocean Hydrographs, were also built. as the aforementioned "Stvora" and "Donuzlav" (project 862 / P) in the Black Sea Fleet, they are not currently being produced. And those that are still in service were built in the 1980s in Poland.
A total of 18 hydrographic vessels of project 862 were built. Now the Russian Navy has eight - three in the Baltic, two each in the Northern and Black Sea fleets and one more in the Pacific. There, by the way, the hydrographic vessel "Marshal Gelovani" took part in a long voyage, which was made by a group of Pacific Fleet ships to the Hawaiian Islands. The participation is understandable - the vessel is equipped with two Don radars, a Rumb radio direction finder, and equipment for bathythermographic, meteorological and chemical-hydrological observations.
This is the general current trend of the entire Russian Navy - we are building small-class ships, but with great potential. It is likely that project 23040 G also has some exceptional features in the field of hydrography. And if in the same Black Sea it will accurately carry out its tasks and lay underwater routes for the "Varshavyanka", then already in the Mediterranean with its depths up to 5120 meters and storms, as, for example, in January 2020, when the height of the waves of the storm Gloria in the region Valencia was 8 meters, it is simply dangerous for such a BGK to be.
