    Freeboard is very high, exaggerated by the covered bow.
    Its a cable-layer, apparently related to the new hydrophone cable network.

    Not really, pretty standard for an offshore services vessel.

    eg Skandi Hawk (offshore supply vessel). Freeboard varies with primary function.

    Interesting... is that a 57mm gun at the extreme back or a 76.2mm gun?

    Looks like a 57mm gun to me... interesting they are using both 30mm gatling and 57mm... hints that perhaps they will see them as complimentary and use them together rather than replace the 30mm with 57mm.

    Sound like a sensible thing to me... the 57mm would certainly pack range and punch, but 30mm rounds are cheaper and easier to carry in large numbers... and many targets don't need a bigger round.

    The former gun probably didn't had a good CIWS caracteristic so they put the ak630. I'm surprised by the size of the gun, the ground version is much smaller. Are the munitions inside of the turret or under the bridge like in bigger guns ?

    We may see that gun ending on Gorshkovs as a secondary CIWS if it works well.

    That would explain its size... though in fairness, while being a very big 57mm gun turret it is actually a rather good sized 76.2mm turret.

    I would assume all the clever new rounds for the 57mm gun will be adapted to larger calibre shells like they did with their guided artillery rounds for land based guns.

    Rosgvardia received the first anti-sabotage boat of project 21980


    Auxilliary vessels, Special-purpose and minor naval ships - Page 13 75289110


    Vympel Shipyard has signed a contract for the construction of four anti-sabotage boats of project 21980 (code "Rook") for the Federal Service of the National Guard Troops of the Russian Federation.
    The boats are designed "to perform special tasks in the field of activity of the troops of the national guard of the Russian Federation" - in fact, as already reported, the main task of these boats as part of the Russian Guard should be the protection of the Crimean bridge.

    To date, 22 anti-sabotage boats of Project 21980 have already been ordered for the Russian Navy, of which 19 boats were commissioned since 2010 (ten were built at Zelenodolsk Plant named after A. Gorky in Zelenodolsk, four at Shipbuilding Vympel plant in Rybinsk, and five at Vostochnaya Verf OJSC in Vladivostok). Of these 19 boats, six are part of the Black Sea Fleet, five each are part of the Northern and Pacific Fleets, two are part of the Caspian Flotilla and one is part of the Baltic Fleet.

    The official launch of the Akademik Ageev oceanographic research vessel

    Reportedly, on November 21, 2019, at the Kanonersky Shipbuilding Plant CJSC (Kanonersky Island, St. Petersburg), an official ceremony was launched to launch water from the floating dock of the first-class oceanographic research vessel (special purpose) Akademik Ageev (serial number 451) of project 16450 (code “Garage-Guys”), under construction for the Main Directorate for Deep-Water Research (GUGI) of the Ministry of Defense of the Russian Federation.

St. Petersburg, 11/21/2019 (c) VKontakte / vk.com/bolshayaigra_war


    As a source in the shipbuilding industry told Sudostroenie.info, the event was held in working order with the participation of representatives of the Main Department of Deep-Water Research of the Ministry of Defense of Russia, representatives of the Pella plant, design organizations - the Malachite and Northern Design Bureau, as well as the workers of the Kanonersky factory.

    On the bmpd side, we recall that the construction of the Akademik Ageev research vessel was carried out for the State Research Institute of Civil Engineering at the Pella Leningrad Shipyard OJSC (Otradnoye, Leningrad Region) since 2015. The official laying ceremony of the Akademika Ageev was performed at the new shipbuilding complex of the shipyard Pella "September 15, 2016. The lead developer of project 16450 is Severnoye PKB JSC (information on design and development work on this vessel was contained in the bureau's annual report for 2015).
    The technical launch of the Akademik Ageev vessel at the Pella plant was carried out without wide publicity on December 21, 2017. Apparently, in 2018-2019, work on the ship on the "Pella" was practically not carried out. On August 31 and September 1, 2019, the Akademik Ageev vessel was transferred along the Neva from Pella Leningrad Shipyard OJSC for completion at Kanonersky Shipbuilding Plant CJSC (Kanonersky Island, St. Petersburg).

    According to one source, the transfer of the vessel for completion to the Kanonersky shipyard is due to the absence of a dock of the appropriate size on Pella necessary for docking during the completion process. Now, "Academician Ageev", after docking, was officially launched at the Kanonersky Plant. The deadline for the ship, however, remains unknown.

    Poseidon is not fired, it is launched. Wink

    Could also be used to launch real ones in wartime.

    I'd suggest that this is a mass simulator for testing the deployment of Poseidon on surface vessels.  Apart from use as a counterforce strategic deterrent, it could serve as a super-heavy smart torpedo for attacking surface forces, and carried on specialist surface combatants or even requisitioned civvie transports when packaged in a containerised form.

    How big would a surface combatant need to be to carry a pair of Poseidon? Lets say a 2000-2500T corvette?

    Thinking bigger, a few carrier-killer destroyers able to strike a Seppostani CVN from several thousand kms would be a nice addition to any future Russian naval groups tasked with power projection in global hotspots.  It would certainly complicate the threat assessment for the USN.  Very Happy    

    Its plausible that this particular setup could be for test unit retrieval, but I expect they would recover a spent round in a vertical lift, either nose or tail first.  Recovering over a stern roller would result in localised bending stresses and would risk both surface and structural damage.

    This would more likely be an improvised launch arrangement for a commandeered civvie, ie for use in times of crisis

    It is supposed to operate a 1km deep or more so I rather suspect its structural strength is pretty solid... It may not have any air filled internal compartments at all... it could be designed to allow internal compartments to fill up with water at great depths so there is no problem with de-pressurisation or pressure differential between sections.

    Strong structure would make it a very difficult target to deal with too... generally a torpedo destroys a sub simply by the uncontrolled letting water in and air out and anyone who as popped a balloon knows even with a thick skin once they are pierced the pressure differential does the rest... but what if there is no pressure differential... an outer wall of a submarine is strong to prevent water coming in but because water does not compress the hull of a sub is supported by the water behind it but the reverse is not true from the outside a pressure wave moving through water hits the outer hull with only air behind it to support it and of course it will collapse fairly easily.

    The double hulled submarines with outer hulls with water behind them are much better at reducing the effect of torpedo explosions... to the point where modern torpedos are designed to explode underneath subs and ships creating an enormous gas bubble that rises up and tries to lift a narrow section of the ship out of the water or the sub in the water... in both cases generally breaking the back of the structure and smashing it into at least two pieces...

    For a water filled unmanned torpedo type weapon things might not be so simple...

    He is probably talking about the Project 02510 BK-16 or Project 02511 BK-18. I don't think that people on the internet were able to identify each and every one of them that was delivered yet.

    There was talk of building another 6 Dyugon but production of both appear to be over for the time being. Maybe once the other projects slow down.

    Russia Designs Unique Ship-Lifting Vessel

    The Krylov State Research Center designs a new multirole facility capable to lift sunken objects of various types, the center’s experts told Mil.Press Today. The project 23570 ship was presented at Neva-2019 exhibition in a limited-access manner.

    The vessel will lift different objects from the seabed, including ships, submarines, and other equipment posing threat to marine environment. It can also be used for development of offshore oil and gas resources (transportation and underwater engineering operations, e.g. assembly, inspection and maintenance of submersible pipelines).

    According to designers, Project 23570 involves a whole range of innovative ship-salvage solutions; several R&D works are currently carried out in this area. One of them named Tekhnologia-ATP is aimed at "development of basic project of integrated technology and equipment for searching, identification, lifting and delivery for further disposal of potentially hazardous underwater objects". The ship will interface with the marine infrastructure available on the Kola Peninsula.

    A naval insider said the ship-salvage issues remained topical and needed some purpose-built technical solutions. For one, within the next few years it is planned to lift PD-50 floating dock and a number of sunken submarines. Also, the Project 23570 vessel will plant and remove different underwater assets on the seabed, and attend the Russian Navy’s search and rescue operations.

    It is planned to kick off building the ship in 2020’s. There will be a single vessel in the project, with the homebase on the Kola Peninsula. Ice class of the future catamaran-type ship is Arc4. Its length is 137 meters, beam is 36 meters, draft is 7.5 meters. Deadweight at design waterline is 10,000 tons. The joint-action lifting system can lift a 14,000-ton object. It is based on 56 lifting gears with capacity of 250 tons each. The load-gripping device consists of 14 modules lifting 1,000 tons each.

    Nice.

    Don't they already have an ancient ship that does a similar job... it was made in 1918 or something and is the oldest operational ship in the Russian Navy... but it does a good job so they keep using it. Found it... Kommuna...

    This will be interesting and certainly clearing a lot of crap off the sea floor and also placing certain items around the place would be useful too.

    Yes the Kommuna

    It was actually launched in 1915 and started its service life in the Tsarist fleet - was called the Volkhov back then.

    So it served through both world wars, 3 completely different political orders, and over 100 years

    A real veteran to be sure, I think it's the oldest ship still in active service in the world

    Perhaps the Russian Navy is thinking of retiring it at last. Or maybe it just needs something a little more modern to augment it.

    Russian Arms Supply Ships to Get Domestic Deck Equipment

    LLC Ship Building Ship Repair (SBSR) has started production of in-house designed launch/recovery systems for Project 20360M sea-going armament carriers being built at Vympel Shipyard (Rybinsk, Russia) for the Russian Navy, the company’s head designer Evgeny Zozulya told Mil.Press Today.

    According for him, most components of launch/recovery systems for boats (RB20) and rafts (RB30) are made in Russia.

    Only windlasses and slewing rings were imported, specified Zozulya. The company also produces spreader bars, lifting gears and electric vacuum pumps for the arms supply ships.

    About a half of Russian deck equipment market is currently occupied by imported products, a top manager of a Russian marine cranes manufacturing facility shared. Domestic producers are mainly wending the way of local assembly of their Western partners’ projects, since the ‘from scratch’ mastering of technology requires huge investments. Another problem, speaking of defense contracts, is complex approval procedures.

    Up to 80% of the Russian marine cranes market is controlled by Palfinger now. Among others, the company owns the INMAN plant in Bashkiria. In summer 2017, the Kingisepp Machine Building Plant declared preparation to localize manufacturing of marine cranes by Italian Sormec. Later on, Sormec changed the partner in Russia for SBSR. According to a well-aware insider, the Italian company then opted out of the full localization in Russia. So far, Mil.Press Today has failed to find out about the plans of SBSR and Sormec to arrange joint production of deck equipment.

    Project 20360M sea-going arms supply ships were designed by Vympel bureau in Nizhny Novgorod. They are built at the same-named shipyard in Rybinsk; two ships of the kind were keel-laid on May 5, 2017 and March 15, 2018. They are to be handed over to the military in 2019 and 2020, respectively. The lead ship will be deployed at the Black Sea Fleet, the first serial one will serve at the Baltic Fleet.

    Russian Coast Guard Patrol Ships to Get Home-Made Helicopter Hangars

    All serial Project 22100 Ocean-class coast guard patrol ships will be equipped with Russian-made retractable gates for helicopter hangars, Boris Leikis, CEO of Almaz Design Bureau told Mil.Press Today.

    Supervised installation of the first import-substituted product was held in September 2018 on the second patrol ship of this type, Petropavlovsk-Kamchatsky, being built by Zelenodolsk Shipyard (member or Ak Bars holding).

    According to the ship’s designer, the question is replacement of the products made by Dutch company Mafo. While the lead ship, Polyarnaya Zvezda, has foreign-made gate, all further patrol craft of the series will be equipped with domestic ones. Thus, this element of the helicopter hangar has become Russian.

    "The gate is based on the Russian technology and equipment, and made by Vineta, a local company from the Leningrad Region", added Leikis. "Everything operates perfectly; the fully-equipped ship has already passed mooring trials, now we’re preparing for the shipyard’s ones. The product is up-to-date and meets all appropriate requirements", he said. Based on the tests results, the gate has been commissioned by the Russian Armed Forces. As is planned, the new retractable gate is to be mounted on Project 23550 patrol icebreakers as well.

    Sergey Vlasov, an advisor to CEO of Nevskoye Design Bureau told Mil.Press Today that their ships were equipped only with Russian-made retractable gates. He emphasized the importance of using the national components.

    "The gate constitutes a U-shaped guide frame that consists of two vertical (left and right) and a top beam, retractable bars, an electric motor, and a hand drive", the press service of Vineta machine building plant reported to Mil.Press Today. "Opening and closing is performed through vertical sliding of bars driven either by electric motor or manually".

    "The gate is adapted for severe weather conditions, including polar latitudes", shared Konstantin Sidorenko, the project designer and head of the heat exchange equipment sector at Vineta. "The telescopic-type enclosure works at low temperatures, too, cleaving up to 60-mm thick ice. Also, it is equipped with electric and mechanical protection systems".

    The gate is designed to withstand the wave load of up to 10 kN/sq m (1,000 kg/sq m), ensuring heat insulation and occupying minimal space in the opened position. The box-shaped section of the bars provides for an air clearance that reduces moisture condensation inside and ice coating outside.
