Project 677 Lada Class Project Amur 950 / Amur 1650 Class Submarines

The Project 677 Lada Class diesel-electric submarines are being built by Admiralty Shipyard for the Russian Navy. The class is also called the Petersburg Class, after the lead submarine. The Lada Class succeeds the Kilo Class submarines.

The keel for the lead sub in class, Sankt-Petersburg (B-585), was laid down in December 1997 and launched in October 2004. The submarine was delivered to the Russian Navy in April 2010 and commissioned in May 2010.

B-585 St. Petersburg  –

The keel for the second submarine, Kronshtadt (B-586), was laid in July 2005 and the launching ceremony was held in September 2017. Commissioning of the Kronshtadt submarine is scheduled for 2019.

The keel-laying ceremony of the third submarine, formerly known as Sevastopol (B-587), was held in November 2006. The submarine was renamed as Velikie Luki and re-laid in February 2015 due to a redesign, after continuous delays. The launch of Velikie Luki is expected to take place in 2019, with commissioning slated for 2021.

The Russian Navy plans to procure a total of eight Lada Class submarines.

Planned versions

The engineering office Rubin, in liaison with the Chantiers de l’Admiralty, is proposing, alongside the project 677 for the Russian Navy, an export version called AMUR, and available in several versions. They are all designed to accommodate the KRISTALL-27E anaerobic propulsion system. The engineering firm Rubin announces that it can also equip them with the Siemens AIP system that equips German U-212 / U-214 submarines. The tonnage varies from 550 to 1850t in surface, and the equipment is of course adaptable to the wishes of the customers. No orders seem to have been obtained for the time being.

In addition, there are many variants. We can retain the following principal:


Amur 1650

Based on many years of experience in operation by the Russian Navy and fleets of other countries in various regions of the World Ocean of diesel-electric submarines of projects 613 (Whiskey), 641 (Foxtrot), 641B (Tango), class Kilo, TsKB MT “Rubin” developed projects of non-nuclear submarines of the fourth generation of the class “Amur” (Amur 1650 and Amur 950).

The submarine “Cupid 1650” has a smaller displacement compared to submarines of the “Kilo” class. Its distinctive features include the possibility of salvo missile fire at sea and ground targets of up to six missiles in a volley, the availability of modern radio-electronic weapons and a hydroacoustic complex with a unique noise-sending antenna that can detect particularly low-noise targets at a great distance.

Amur 1650 –

The level of the acoustic field of the submarine “Amur 1650” is several times lower than that of the “Kilo” class submarines, which are considered to be the lowest noise in the world today. The submarine is equipped with a new generation of electronic weapons, using the achievements of world radio electronics in recent years.

Amur 1650

It is possible to equip the submarine with an air-independent power plant with electrochemical generators, which makes it possible to significantly increase the underwater autonomy and range of navigation. Such an installation with reagent stocks is placed in a special compartment-module, which can be built into the submarine both during construction, and during repair or modernization.

The submarine can be operated in any areas of the World Ocean, except areas with a solid ice cover, under any weather conditions, in shallow and deep water areas.

When creating a submarine, equipment and armament of both Russian production and the customer country or equipment of third countries can be used. Amur-1650 data Translated by google – Source

Amur 950

The submarine “Amur 950″ has a smaller displacement compared to the submarines of the class ” Kilo ” and “Amur 1650″. The peculiarity of the submarine is the presence of 10 universal vertical launchers of the ” Club – S ” missile system , which makes it possible to carry out a 10-missile salvo with cruise missiles for maritime and land targets for no more than 2 minutes. For self-defense, there are small-sized hydroacoustic countermeasures devices placed in launchers in the superstructure of submarines.

The integrated combat control system with the latest radio electronic subsystems allows solving all the tactical tasks facing non-nuclear submarines. Due to the relatively small displacement, the submarine “Amur 950” will have an advantage over submarines of similar class by the criterion “efficiency-cost”.

Lada Class design features

Amur 1650 –

Lada Class diesel-electric submarines are designed by the Russian Rubin Design Bureau. The ship incorporates a mono-hull design. The surface displacement was reduced to 1,765t from 2,300t of the double-hulled Kilo Class submarine.

The full submerged speed has been increased from 19kt to 21kt, and crew complement has been decreased from 52 to 35.

B-585 St. Petersburg – igorrgroup.blogspot.comB-585 St. Petersburg – Vitaly V. Kuzmin
B-585 St. Petersburg – Vitaly V. KuzminB-585 St. Petersburg –

The submarine has a trimmed profile equipped with sophisticated torpedo and missile systems. The hull is covered with a new anti-sonar coating for low acoustic signature.

Lada Class uses hydrogen-oxygen fuel cells generating electricity for low noise operation. The submarine is fitted with Litiy automated combat control system. The integrated system controls the combat and technical systems of the submarine.

Unique AIP design

The Russian AIP design is unique because hydrogen required for power generation is obtained by means of diesel fuel reforming onboard the submarine. Hydrogen is not stored onboard and is produced as much as needed, which increases the safety of the propulsion plant. Ordinary diesel fuel, which is standard for all diesel-electric submarines, is used for generating hydrogen. It needs no extra component and, hence, extra reservoir for storage. There is also no need for special infrastructure on shore to generate and store hydrogen. To cap it all, the AIP features low noise and high efficiency. Source

The Lada Class has a surface speed of 10kt and submerged speed of 21kt. The propulsion system provides a submerged cruising range of 7,500nmi at an economical speed of 3kt. The maximum diving depth is 300m. The submerged displacement of the boat is 2,700t.

Closeup of torpedo hatches on the B-586 Kronshtadt – Новости на Первом Канале

Club-S carries up to 400kg warheads and can strike land and naval targets within a range of 300km. The six 533mm torpedo tubes fitted on the ship can launch up to 18 torpedoes, tube-launched anti-submarine and anti-ship missiles.

Club-S Integrated missile systems


High-performance submarine-based Club-S and ship-based Club-N integrated missile systems are designed to engage surface ships and submarines in conditions of intensive enemy fire and electronic countermeasures. Both systems employ unified combat assets – two types of anti-ship cruise missiles and an anti-submarine ballistic missile. Club-N missile system features standardized launch units and transport-launch containers.


Integrated missile systems include:

  • 3M-54E anti-ship cruise missile (Club-S) comprises a booster, low-altitude subsonic sustainer, and a separable supersonic warhead. 3M-54TE ASM (Club-N) features a TLC to ensure vertical launch;
  • 3M-54E1 ASM (Club-S) comprises a booster and a low-altitude subsonic sustainer. 3M-54TE1 ASM (Club-N) differs from 3M-54E1 only by having a TLC;
  • 3M-14E land-attack cruise missile (Club-S system) consists of a booster and a low-flying subsonic sustainer. Launched from the Club-N system this missile is designated the 3M-14TE, with the only difference being a TLC;
  • 91RE1 anti-submarine ballistic missile (Club-S) performs a controlled flight to the target area. Its separable warhead is a high-speed homing torpedo with a sonar target seeker.

DM-1 sea mines

In 1957, the Navy received the IGDM-500 small bottom mine, and in 1959 it got the MDT tubular bottom mine and Serpei large bottom mine. In 1961 such unique bottom mines of the UDM family as the UDM large air-dropped mine (1961) and UDM-500 small bottom mine (1965) came into service. In 1979, the UDM-2 mine, featuring fundamentally new performance characteristics, was developed. Later, on the basis of the UDM family of mines, their successors, designated MDM-3, MDM-4 and MDM-5, were developed for export. At the same time, the DM-1 (MDM-1) mine, designed to be laid by submarines, entered service. The latest modification of this mine is the MDM-6.

All of the above mines can be air-dropped, scattered from surface warships and other vessels, and the MDM-1 and MDM-6 types can also be laid from submarines. As regards size and explosive charge, mines can be subdivided into superlarge (UDM-2, DM-1, MDM-5, MDM-1, MDM-6), large (IGDM, AMD-2M, Serpei, UDM, MDM-4) and small (IGDM-500, UDM-500, MDM-3). Source


The mines are fitted with local three-channel influence exploders activated by target’s acoustic, electromagnetic and hydrodynamic fields sensed in a hemispherical danger zone. The exploders allow the mines to be deployed in both three- and two-channel configurations, with any combination of the channels possible. The mines possess effective anti-sweeping protection from modern influence sweepers and resistance to natural clutter owing to advanced exploder operating principle and anti-sweep device logic, as well as mine timing and ship counting devices employed. Intricate planting patterns and camouflage painting of the mines hinder their detection by sonars of surface ships and submarines, or by mine-hunting devices of remotely operated underwater vehicles.

MDM-1 Mod. 1 sea bottom mine

The mine can be laid by submarines equipped with 534mm torpedo tubes and ships fitted with mine-laying rails/ramps or mine-scattering systems. Surface ships can lay the mines at speeds of up to 15 knots, and submarines – at speeds of up to 8 knots.

When the assigned service life of the mine expires, it is self-destroyed.

The Lada Class submarines are fitted with modern sonar equipment such as bow, flank arrays and towed array sonars. The Lira sonar system with quasi-conformal (abutting the hull of the submarine) antenna can detect low-noise targets located at long ranges.

The ship has an inertial navigation system for safe navigation and determination of motion parameters. The system ensures the accuracy of on-board weapons by providing guidance during long underwater operations. The countermeasures are provided by the electronic support measures (ESM) system, radar warning receiver and direction finder.

Propulsion and power of the Russian subs

B-585 St. Petersburg – Russian Marshal YouTube

The submarine’s propulsion system integrates two diesel generators, a main electric propulsion motor, two air independent propulsion (AIP) systems, and a single shaft driving on a skewed seven-bladed propeller.

2 x 28DG Diesel-generator

The diesel engine is located in the fourth compartment. For the generation of electricity, two 28DG generators are used, coupled with rectifiers with a capacity of 1000 kW each. The energy is stored in two groups of storage batteries. In each of them there are 126 elements (they are in the first and third compartments). The total aggregate capacity of the entire plant in the peak state is 10580 kW / h. The working motor is electric, it is excited by permanent magnets. The SED-1 grade, the specific power is 4100 kW. Translated by google – Source

The AIP system based on oxygen / hydrogen fuel cells increases the Lada Class submerged endurance from 15 to 45 days. It also reduces noise by avoiding the need for frequent battery recharge by diesel generators.

The diesel engine operating short time in the snorkelling mode increases the endurance of the submarine. The submarine also has a storage battery with an increased service life.

KRISTALL-27E anaerobic propulsion system

“The Lada project is an unconditional breakthrough and improvement of technologies that exist on traditional diesel submarines. Of course, there will be a certain continuity, all the best that we will get through the Lada, we will invest in a new large non-nuclear submarine, which will be created already within the framework of the formation of the next generation, “he said, answering the question whether Lada VNEU .  According to him, now there are two projects of air-independent plants. “One (installation – TASS comment) was carried out by CDB” Malakhit “, the other – TsKB” Rubin “. They use different principles, “Rakhmanov said. “But we hope that in the near future with the help of the Ministry of Industry and Trade we will go to mock testing in water,” he said. According to him, now both installations exist as stands and show good results. TASS.  Translated by google – Source

      Thanks for the vid really helpful no wonder the standard config of the Armur has no AIP and the control room is less sophisticated than the Lada I just added the Armur control room pic yesterday


  1. Nicky

    In my Opinion, Thailand should have gone with the Lada/Kilo class SSK. At least with Russia, you get the Transfer of Technology, where you can build your own SSK Submarines.


      1. Nicky

        You can still launch missiles from a torpedo tube that was clearly demonstrated by Russia on a Kilo class SSK. What I think Thailand is looking is for an SSK to act as a Cruise missile platform and any SSK is capable of launching a cruise Missile via a torpedo tube.
