Diesel "Varshavyanka" won the duel at the atomic "Los Angeles" Problem American submarine is increasingly in emergency situations

In October 2015, the diesel-electric eyeliner of the project 877 "Halibut" "sank" a multipurpose nuclear submarine of the US Navy of the Los Angeles type "City of Corpus Christi" SSN-705. So gives the events of one and a half years ago the American magazine The National Interest. And this is very similar to the truth, since this boat, assigned to the US Navy base Guam, was decommissioned in 2016.

In fact, this is what happened. And the magazine subsequently explains the essence of the incident. During the exercises, codenamed "Malabar", in which surface ships and submarines of India, the USA and Japan took part, the Sindhudhvaj Indian submarine bought from Russia and the American submarine received the task of finding each other in the Bay of Bengal.The Los Angeles boat, despite being equipped with modern hydroacoustic systems, was unable to detect the “Russian woman”.

The magazine explains the situation in this way: “The project 877“ Halibus ”boats are exceptionally quiet and have excellent performance thanks to a diesel-electric power plant. After the dive, they work on electricity, and therefore they are called "black hole".

These boats are a headache for the US Navy. The development of measures to counter such ships has become for Washington a top priority, since the boats of this project are part of the Navy of many potential adversaries, such as China and Iran. ”

True, it is necessary to make a clarification. In itself, electricity does not do great weather in the cause of stealth. There are electric motors on the boats, which, together with the drive and propellers, as well as various “noise on the half-ocean” mechanisms. The “Halibut” boat, also called the “Varshavyanka” (Project 636), is the lowest noise boat in the world. This is achieved not only by minimizing the mechanical noise from the units inside the hull, but also due to the shape of the boat with high hydrodynamic quality, and a special hull coating,and special design screws installed in the fenestron (relatively speaking, in the pipe).

And, speaking of the presence of these "black holes" in many potential opponents, the magazine is absolutely right. Varshavyanka was specially designed for export. Initially, it armed with submarines of the Warsaw Pact member countries. Now the “Varshavyanka” under construction in equal proportions come in both the Russian Navy and the Navy of many countries of the world.

Having found the American boat, Indian submariners accompanied it for some time, continuing to be invisible on the screen of the Los Angeles sonar. And then, coming to the shock position, fired a conventional volley with 533-mm torpedoes. And the American boat was amazed.

Of course, also conditional. As the officer of the Indian Navy told the India Today publication, “this was a great achievement for us.”

US nuclear submarine "Los Angeles"

 

The National Interest started this entire conversation solely because it justified the need for serious new investments in the construction of new American multi-purpose nuclear submarines of the fourth generation of the Virginia type.Because boats of the Los Angeles type, the production of which began in 1972, do not meet modern requirements since they become prey to the Halibus. “Reports from India may be wrong,” the magazine writes, “and yet the incident underscores the need for the speedy and complete replacement of Los Angeles-type submarines with Virginia class submarines.”

However, an early and complete replacement will not work, even if the budget allocated for the construction of multipurpose submarines is repeatedly increased. And not only because the purchase by the Pentagon of one Virginia costs almost $ 3 billion. Too much need to build boats to fulfill the wishes of the military observer of The National Interest.

Over the years 62 boats of the Los Angeles type have been built. Currently in operation 35.

Now in the ranks are 13 boats of the type "Virginia". Two more are launched and three are being built. And 10 are ordered.

It is difficult to say what exactly the magazine means by replacing old boats with new ones. Two scenarios are viewed.

1. Instead of 35 currently operating Los Angeles-type MPLATRKs, it is necessary to put into operation as many new Virginias.

Consequently, the existing order for the construction of 10 submarines needs to be expanded to 30 units (out of 35 we deducted 2 lowered and 3 under construction).

On average, one boat is built per year. That is, a complete set of the 1st version of the replacement should be ready in 30 years, at the end of the 40s. It is unlikely that such terms satisfy the requirements of the “prompt replacement” magazine.

2. It is necessary to increase the number of Virginia-type MPLATRKs to the quantitative composition of multi-purpose Los Angeles-type boats when they single-handedly solved the tasks assigned to submarines armed with torpedoes and cruise missiles. In the best of times, before the start of writing off, there were 62 units in the US Navy. With the help of simple arithmetic operations, we find that the 13 submarines that are available and another 5 submarines that have been launched and are being completed are required to add another 44 submarines.

And, therefore, the end of their construction will be completed in the second half of the century. Or rather - in 2061.

Of course, the replacement of veterans of the multipurpose American submarine fleet has become a matter of urgency at the beginning of this century. And not only because the “City of Corpus Christi” SSN-705 lost a duel to “Varshavyanka”, operated by the Indian Navy, a year and a half ago. The fact is that since the end of the 80s "Los Angeles" - the most emergency submarine of the US Navy.

For 30 years, this particular boat survived more than ten accidents and was involved in various kinds of incidents. Here are some of them.

In May 1989, the Houston submarine NNS-713 was returning from the shooting of the film “The Hunt for the Red October”, which talked about how the captain of the Soviet submarine led her to the shores of the United States in order to surrender to the American authorities.

Not far from the SSN-713 base, being on the surface, hooked the cable on which the tug pulled the barges. The captain gave the order to dive, and the boat pulled the tug to the bottom. At the same time one person died.

In February 1992, the Baton Rouge SSN-689 submarine, while in the territorial waters of Russia, secretly followed the course of the exercises of the Northern Fleet. The captain acted so ineptly and brazenly that he collided with our boat K-276 of Project 945 "Barracuda". The Russian boat received minor damage and was repaired in the summer of the same year.

A fire broke out in the American boat, several sailors died - the exact number of victims was not made public. The SSN-689 had a long time to eliminate the dents and cuts of the body, as well as the consequences of a fire.

A year later, a similar story happened in the Barents Sea. The Russian boat K-407 of the “Dolphin” project after a collision with an “American” was repaired as soon as possible.A "Grayling" SSN-646 had to be written off due to the inability to recover.

"Los Angeles" has repeatedly flown both on civilian ships of other countries, and on its own warships.

The greatest number of casualties was in 2001 in a collision with a Japanese fishing boat in the region of the Hawaiian Islands. In case of emergency boating, she rammed the schooner, which instantly went to the bottom, killing 9 fishermen. 26, fortunately, managed to save.

The greatest damage to its own fleet due to navigation errors was caused in March 2009, when the Hartford SSN-768 flew into the Strait of Hormuz on the airborne helicopter transport dock "New Orleans".

A diesel fuel tank was broken through the vehicle, which caused serious pollution of the strait and resulted in the payment of a serious fine. On the boat 15 sailors were injured. Both the boat and the transport were sent for repair.

At the same time, the boat captain was removed from command due to the “loss of confidence.” And this is quite natural, since it was with him that six years earlier the boat ran aground off the coast of Sardinia, seriously damaging the rudders, sonar and other equipment.

Sometimes the collision was very serious.So, in January 2005, the San Francisco SSN-711 submarine collided with an underwater mountain at a speed of 35 knots and at a depth of 160 meters. The crew with great difficulty was able to lift the submarine to the surface of the sea, since the front ballast tanks were damaged. 98 people were injured in the form of broken bones and lacerations. One person passed away. 30 people were hospitalized.
