Project 677D Kronstadt

"Lada" is designed to conduct independent operations against submarines and surface ships in a limited area, ground attacks using sea-based cruise missiles, anti-submarine defense in coastal areas, narrow areas and in torrential zones, and maritime communications in limited areas. They can be operated in any weather conditions in shallow and deep water areas in any area of ??the World Ocean, except for areas with a solid ice cover. The submarine has increased autonomy - up to 45 days, increased cruising range in the underwater position - up to 650 miles at a speed of three knots.

Boats of this type have a single-hull architecture, compared to the submarines of the 877 Lada project, they have a lower noise level, a high degree of automation, reduced by almost 1.3 times the above-water displacement, and increased underwater speed. The displacement is approximately 1765 tons (2650 tons - underwater). At a depth, they can accelerate to 21 knots (about 38.9 km / h), on the water surface - ten knots (about 18.5 km / h). The working depth of the dive is 250 m. The crew is 35 people.

The main armament of the "Lad" is the cruise missiles of the "Caliber" complex. There is the possibility of conducting salvo missile firing at sea targets. The ship has six torpedo tubes of caliber 533 mm, the ammunition includes 18 torpedoes, 16 torpedo-missiles or 44 mines.

The main power plant is diesel-electric (the main rowing electric motor with a capacity of 4100 hp and two diesel generators with a capacity of 1,000 kilowatts each). It is possible to equip the submarine with an anaerobic (air-independent) power plant with electrochemical generators, which will significantly increase the autonomy and range of navigation. The development of such an installation as of 2018 is conducted by the Central Design Bureau of Marine Engineering "Rubin".

In St. Petersburg, the shipyard "Admiralteiskie Verfi" launched the second diesel-electric submarine of project 677 "Kronstadt" on 20 September 2018. It was planned that the Navy (Navy) of Russia it will arrive in 2019. Developed in the Central Design Bureau of Marine Engineering "Rubin", the boat belongs to the fourth generation of non-nuclear submarines of the "Lada" series. Thanks to the use of new solutions in the design of the hull, special coating and the latest radio electronics, they have unsurpassed secrecy, less noise and a number of deeply advanced systems compared to the third generation submarines.

The first boat of this project - "St. Petersburg" - was in trial operation in the fleet. At the moment they are building another "Lada" - "Velikie Luki". Also in plans to sign a contract for another two submarines. At the Russian Navy, it is believed that in the future it will be the boats of this type that will become the backbone of the Russian non-nuclear submarine fleet.

In tests of the lead boat of this series in the second half of the zero years, in particular, problems were identified with the acoustic complex and the main power plant. In November 2011, it was decided to re-equip the head submarine and complete the already installed boats on the finalized project - with the modernization of control systems, electromotion, navigation systems.

Kronstadt was laid in 2005, but four years later its construction was suspended and was resumed only in 2013. Therefore, "the significance of this event can not be overestimated, " Alexander Buzakov, General Director of Admiralty Shipyards , said at the solemn launching ceremony. "The ship has undergone both stops in construction and stops in financing, but nevertheless, the descent was held today." The delay in construction made it possible to take into account the experience of building and operating a submarine "St. Petersburg" on this ship," he said.

Admiralty Shipyards" had contracts from the Defense Ministry for the construction of a second boat (first production) "Kronstadt" and to build a third boat (second series) "Velikhy Luke." "These two Project 677 boats for the Navy Russian built in the same modifications to improve the draft, but without air-independent power plant (VNEU). This decision was taken command of the fleet to the ships were built as soon as possible", - said the head of "Rubin".

The third non-nuclear submarines of Project 677 "Velikhy Luke" was laid down at the "Admiralty Shipyards" 19 March 205, the General Director of CDB ME "Rubin" Igor Villeneuve said at the international aviation and maritime exhibition LIMA-2015.

Parent Boat Project 677 - "Saint Petersburg" - since 2010 was in trial operation. Construction of the second and third boats laid down in 2005-2006, was adjourned. As of May 2015, the first submarine of this generation, the B-585 Sankt Peterburg, was undergoing a trial operation, but subsequent vessels had been heavily re-designed. The B-586 Kronstadt was set to join the Navy in 2017 and the B-587 Velikiye Luki in 2018. At the end of 2014 the "Admiralty Shipyards" reported that it expected to receive a new contract for a series of Lada submarines for the Russian Navy. Industry had improved propulsion systems for these submarines, increasing reliability and reducing noise.

On 24 November 2011 CEO CDB ME "Rubin" A.Dyachkov said that the next two boats of the project will be upgraded for the updated technical project - code-named pr.677D. The new technical project would be ready in 2013, after which the second and third boats of Project 677 will be completed on the new project.

On 09 February 2012 the information was essentially confirmed the Russian Navy Commander Vladimir Vysotsky, saying pr.677 built boats will be upgraded. As commander in chief announced the drafting of air-independent propulsion system, which can start to experience boating pr.677 in 2014. According to an interview with the director "Admiralty Shipyards" Alexander Buzakova the completion of the boats will start in 2013 in the case of their inclusion in the state defense order for the year.

In the case of availability of regular lithium batteries will be installed on the submarine "Kronstadt". As of September 2012 the funding for works on a lithium battery is selected, experimental work conducted. On 09 July 2013 the contract to build submarines pr.677D ("Kronstadt" and "Sevastopol") came into effect. These boats with updated design will differ somewhat modernized equipment and updated electric propulsion system The second and third submarine of Project 677 "Lada" will be transferred to the Russian Navy later ahead of schedule - in 2019, said a TASS source in the main command of the Russian Navy 16 January 2016. In 2015, a source in the defense industry told TASS that the navy will receive two "Lada" in 2017 and 2018. These data confirmed the first deputy general director "Admiralty Shipyards", where submarines are built, Andrei Bystrov.

"The postponement is expected on both "Kronstadt" and "Velikiy Luke" ["Great Luke"] to 2019", - he said in the Main Command. According to him, this is due to adjustments to the state defense order. Their construction was suspended and resumed only in 2013. The source stressed that the second and third series of submarines being built "with all the observations identified in the operation of the lead unit," (" Saint Petersburg" - a comment by Tass) in the Northern Fleet." As for the possible installation of these submarines airindependent energy installation, "you must wait for the results of its sea trials," said the official.

The construction of submarines of Project 677 has been going on for almost 20 years: the boat at the head series "St. Petersburg" was laid down in 1997 and since the transfer of the fleet in 2010, as of early 2016 was still in trial operation.

The contract between the military and Admiralty Shipyards for the completion of the second boat entered into force on July 9, 2013, at the end of 2014, a contract was signed to continue construction of the third boat. Initially, it was laid down on November 10, 2006 as "Sevastopol", and in 2015 it was re-installed as "Velikie Luki". Then it was reported that this submarine will be built taking into account the adjusted technical project developed in the Central Design Bureau of Marine Engineering "Rubin", based on the experimental operation of "St. Petersburg". The designer has carried out work to improve the boat and create modernized complexes - navigation systems, shipboard technical equipment management and electric motoring.

In June 2017, a source in the Russian delegation at the International Naval Show told TASS that the boat "St. Petersburg" would be repaired and modernized. "It's about not only carrying out an average repair of this ship, but also upgrading it to the state of the first serial (the second one - TASS commentary) .This work will take two or three years," the agency's interlocutor said, without specifying the time start repair.

"Order of the Ministry of Defense of the Russian Federation for two Lada" - "Kronstadt" and "Great Luke" - indicates that the fleet has set the task of increasing the potential of non-nuclear submarine forces, which we are obliged to fulfill, "said in 2016 in an interview with Tass head Central Design Bureau of Marine Engineering "Rubin".

It had been repeatedly reported that the second and third submarines, Kronstadt and Velikiye Luki, were to be transferred to the Russian Navy in 2018 and 2019, and the contract for the fourth was to be signed in 2018. In the summer of this year, USC president Alexei Rakhmanov said in an interview with TASS that the main reason for postponing the delivery of the second and third Lada are electric submarine engines, "for which questions remain". During the launching ceremony of the second boat, the general director of the Admiralty Shipyards reported that the St. Petersburg shipbuilding company was planning to sign a contract for the creation of the fourth and fifth submarines of the 677 project next year under the program of the state armament program.
