The number of nuclear submarines with batteries classified.

Each accident is the source. “Fontanka” found out, like a burning in the Barents sea the submarine was lithium battery.

Breakthrough for the submarine fleet of lithium-ion technology St. Petersburg designers have introduced not less than five years. The number of nuclear submarines with batteries, the description which follows the word “explosiveness” cannot be told because of the secrecy.

“Do not want!” “Why do you ask these questions? You know what don’t answer” “what do you here with me?” This is a reaction to the attempt to understand, whether there will be a tragedy in the Barents sea in the beginning. To find out who set fire to submarine discussion lithium battery, the official speakers are not needed. The procurement website calls the name, surname, and position. “Fontanka” only repeats of the publisher.

Fourteen sailors died 1 July as a result of volume of fire on a nuclear submarine. The bulk of the fire is told in the condolence of command of a military unit. The term is used when the size of the flame coincides with the area of the room. This effectively means that in a sealed compartment of the submersible, there is not one cubic centimeter, not on fire.

Minister Shoigu reported to President Putin that the fire originated in the battery compartment. As it became known “Fontanka”, the Commission for the reasons announced the preliminary version, short circuit, thermal runaway and explosion of the lithium battery.

Lithium ion technology is officially only referred to as promising for deep water work. Soviet engineers developed for the nuclear submarine fleet of the silver-zinc battery. Their main difference from lithium – they explode and are more expensive. Technical experts are perennial disputes about the application of lithium-ion batteries under conditions of high pressure. Opponents argue increased explosiveness and the difficulty of extinguishing such fire. The guardians insist that progress has passed this puzzle and chemical current source based on the lithium doesn’t hold more catastrophic. (Looks like explosion lithium battery, can be seen here.)

Information about deep-sea submersible, killing hydronauts, as well as the tasks that they perform, are classified. Alien mystery “Wikipedia” refers to the serial number of the submarine design Bureau and manufacturer. RBC sources indicate date of last modernization in 2016. “Fontanka” found a state contract, in which, most likely, was established an experimental battery.

In the contractual relationship of the design Bureau “malachite” and the plant “Sevmash” I joined at the end of 2015. Two contracts have been concluded under the auspices of one, Central, government Contracting, where the Severodvinsk enterprise acted as the Prime contractor, and the St. Petersburg singer.

The subject of the first procurement entitled “Technical support of JSC “PO “Sevmash” for the maintenance of technical readiness of the order, and while performing work on joint solutions”, cost – 81 887 733 rubles. The name of the second lot shorter, “the Work on joint decisions on order”, the price is much higher – 398 586 814 rubles. Both contracts signed in one day, December 17.

Published on the website of public procurement documentation contains mostly vague, but sewn between the lines meanings (digital signage project, the serial number and the military unit) allow us to conclude that the question of modernization of the most top-secret submarine. The work schedule is divided into stages, the last deadline expired in October 2017.

From the “Sevmash” both contracts signed by the Deputy General Director for logistics and material and technical provision does Kruchenkovaof “Malachite” – Deputy for economy and Finance Andrey Cat (one contract) and Deputy for General Affairs Arkady Shilov (second document). Joint work by the rules of the orders, could not take place without military acceptance. All the documentation was agreed by the curator of the “Sevmash”, head of 1059 military representation of the Ministry of defense Dmitry Makarov and the head 342 that control orders “Malachite” of the military representative Filimonov.

Fragment of a contract

In 2014, in an interview with the title “Here is forged the shield of power,” Dmitry Makarov formulated the “red star” its mission: “the Military representative office carries out control over the correct formation of prices for military products, monitors the quality of military products manufactured and supplied under an inter-enterprise cooperation in the framework of the state defense order and controls the work during the warranty and maintenance of ships. I want to emphasize that the main task of the mission remains the quality control of products at all stages of production, including incoming inspection of incoming components, in-process control at all stages of construction up to delivery of products to the fleet.”

The source of the fire, the interlocutors of “Fontanka” is called short circuit and thermal runaway of the lithium battery. The old partner of JSC “SPMDB “Malahit” defines the public procurement system of OJSC “Battery company “Rigel”. At least since 2014, attempts to create lithium-ion batteries for deep-diving vehicles. On its website, “Rigel” reports that success in this direction was reached in 2007.

In open sources “Fontanka” counted at least four contracts that bind “malachite” and “Bolt” the quest for progress. The earliest that issues the procurement website, Dating 2014. Its starting price of 800 thousand rubles, called “Execution of works on the subject “Verify the use of chladone 114B2 to extinguish the fires LIAB consisting of batteries LINGP-150C”.

Chladone 114B2 – regular ognegasitelem on submarines. They surround extinguish fires. It binds oxygen molecules in the air compartment, and the fire goes out by itself. Method is very successful, but in the case of a lithium battery is powerless, as it is when burning itself releases oxygen. System volume chemical quenching on submarines is called the LOCH (boat fire extinguisher chemical).

Following chronology of the contract was signed shortly before the repair of the submarine, in may 2015. Over 173 million “Bolt” was to modify the product “LEE-443 according to the results of trial operation”. By the way, the procurement documentation for the first contract (then signed with the St. Petersburg University of state fire service of EMERCOM of Russia) shows that the product of LI-442 it was also found related to the victim by fire the deep-sea submersible.

Two contract “Rigel” has signed with “Malachite” in 2017: 85 million to establish a submersible Li-helpoemer batteries for ultra-deepwater submersibles “Rus” (crew 2) and 12.1 million on the development of lithium-ion batteries. Cooperating “Rigel” and the developer of submarines of the “Borey” KB “the ruby”. From 2014 to 2016 was signed at least three “lithium” contract for a total amount of 24.5 million rubles.

Office of the JSC “Battery company “Rigel” is located on the Petrograd side. The company calls itself the successor of the founded in 1897, the company “Russian accumulator factories “Tudor”. A subsidiary of scientific-production center “Rigel” is now in the stage of bankruptcy, and his namesake of the scientific-technological company “Rigel” noted intriguing purchases. Twice she acted as a supplier of “Budget investments” for the Ministry of industry and trade (86.9 million in total), and in 2011 sold the St. Petersburg research Institute of ship electrical engineering and technology Li-ion battery for 65 million rubles. Fresh data on the state of the enterprising daughter of SPARK does not. Head “Bolt” last time shared financial results for the year 2017. Its revenues then exceeded half a billion, and a net profit of 77 million.

“Fontanka” referred to the General Director of “Bolt” Yevgeny Volkov request for conversation. For three days there was no answer. One of the former leaders of the battery companies do not want to believe that the lithium battery “Pins” can stand on a submarine. “I think no one would this battery did not deliver. If set, then the idiots. Sorry, I doubt that there is someone set this battery. It was not a place, it was not necessary”, – he said, but to explain said refused.

Design engineer naval Bureau of machine building “malachite” also did not speak. “That I do not understand you, journalists. Know what you no answer, and still continue to ask questions,” sighed Radiy Shmakov. His nerves proved to be stronger than the honored designer Michael Brezina. “No!” – almost shouted the one on duty, “Hello, are you worried about “Fontanka”.

– You don’t even want to hear the question?

– Do not want!

To Chapter 342 military acceptance Filimonova call failed. Its Northern counterpart Dmitry Makarov is on vacation. Acting chief 1059 EAP MO of the Russian Federation Alexander Merkulov was surprised journalistic interest. “And you here with me?” – this form of the answer he chose for the question of whether the revised format of cooperation with the “Malachite” in the light of their work with “Bolt”.

“This information is private, no one should worry that we who have bought, because the cause is unknown yet, – he said and confessed, Investigators, fortunately, did not occur.”

The investigation of the incident in the Barents sea, the Commission of the Ministry of defense. It is headed by the commander in chief of the Navy Nikolai Evmenov. The investigative Committee announced the preliminary inquiry. Criminal case, contrary to the practice (when talking about death), it has not yet become. If the prior version is confirmed, will be the turn to figure out what was the cause of the explosion: a factory defect, error operation or the idea to use this technology under water.

Fourteen senior officers of the Navy were killed July 1 during a fire on the deep-sea submersible. According to “Fontanka”, the explosion of lithium batteries occurred during the docking of the submarine with a nuclear boat-bearer. Killed the personnel of the forward compartments, the survivors are battened down the Central office, completed the docking, turned off the nuclear reactor, and evacuated to the media. The four hydronauts posthumously awarded the star of Hero of Russia, ten people — the order of Courage. Submariners buried at the Serafimovskoe cemetery in St. Petersburg.
