    Two compartment of the ship get flooded, lost propulsion and combat capability.

    The impact profile was more preferable than an anti ship missile.

    Means that the damage can be equivalent with one harpoon, and one onyx could destroy the ship completely.

    Fitzgerald was pierced by container ship's bulbous bow and most of the damage is under the water line. It also hit the compartment where crew sleeps (don't know naval name for that part) hence the missing crew.

    They were probably washed away from their beds and into the ocean.


    don't think so.

    Seems like the container bulb is not broken or damaged, so it pushed to the the side of the ship and cracked few welding.
    If the bulb pierce the ship then it lost.

    Anyway, the energy of the container ship going full speed sideways into the stationary ship and slow to full stop in the navy ship then the energy equivalent of a P-700 impact/explosion energy release.Not considering the fuel .


    This accident had fraction of the energy expenditure of the worst case scenario .

    The bulb is purely hydrodynamic in purpose and would be fairly solid...

    We are not talking about a Sonar radome that contains delicate equipment like a Sonar sensor array.

    This is more like a ramming prow that pushes through the water to make it easier going for the ship to pass.

    Actually it generates a wave that destroy the biger waves created by the ship so that the navigation is better and not affected by the big waves.

    Good.
    Would have been nice to see an actual prototype or pre-series being tested though.

    Russia launches serial production of seaborne air defense missile system

    The development of the Pantsyr-ME seaborne surface-to-air missile and artillery complex has been completed



    MOSCOW, June 23. /TASS/. The development of the Pantsyr-ME seaborne surface-to-air missile and artillery complex has been completed and the system has been launched into serial production, state hi-tech corporation Rostec CEO Sergei Chemezov said on Friday.

    "The development of the seaborne version of the Pantsyr air defense system that has no analogues in the world has been completed. The presentation of the Pantsyr-ME will be held at the International Maritime Defense Show in St. Petersburg," Chemezov said.

    "The complex has already been launched into serial production," he added.

    The Pantsyr-ME is the shipborne version of the Pantsyr antiaircraft missile/gun system. The system’s version for ground forces is called Pantsyr-S.

    The International Maritime Defense Show will be held in St. Petersburg on June 28 - July 2.

    Interesting they have gone for the twin barrel cannon models rather than the gatlings.

    The twin barrel guns have a lower rate of fire but likely less vibration and movement during firing so would generate much tighter groups.

    They already fire at a high rate... 2,000-2,500 rpm per gun, so less than half the rate of fire each, but with better accuracy then fewer rounds would be needed.

    Another factor is the new time fused rounds... the twin barrel design has a muzzle device that can detect the muzzle velocity of rounds as they are fired... I would suspect they could use an induction coil to fuse the rounds as they are loaded, and the coil at the muzzle will determine their precise muzzle velocity, so accurate settings for the distance at which the shells will explode should be rather more effective than with a 6 barrel gatling gun.

    No, just based on photo...

    Previously Kashtan and Kashtan-M have used 6 barrel gatling guns as standard within the Soviet Navy.

    The original Pantsir had single barrel 2A72 cannon with a very low rate of fire but rather accurate.

    They were replaced by the twin barrel 2A38M cannon of the tunguska due to rate of fire issues.

    This is the first time a land based air defence gun/missile system has been adapted for naval use... so would they keep the land based guns or adapt them to the naval guns?

    As I mentioned the muzzle of the 2A38M has an induction coil over one barrel and a shield over the other to measure the muzzle velocity of the rounds as they are fired.

    A fuse setter could be used to set the timing fuse of the rounds based on the data about the incoming threat and muzzle velocity of the rounds as they are fired to ensure rounds detonating near the target to ensure instead of needing a direct hit to be effective, the rounds could detonate in the path of the incoming threat showering them in shrapnel of the exploding shells... an almost guaranteed hit...

    Of course with a gatling gun the radar director can continue to track outgoing shells and perform the same role I suppose.

    KPB Tula make Pantsir-S and Kashtan-M so they could use the gatlings too.

    I think thats just an ordinary Pantsir-S1 module.

    Bunch of details match with normal one, could be just a matter of standardisation but everything I've previously seen including official 22800 display model indicates -M is going to look more like Kashtan

    Russian hi-tech firm to feature submarine Internet technology at St. Petersburg naval show

    The system currently operates aboard nine Russian Navy vessels

    MOSCOW, June 27. /TASS/. Ruselectronics Group, part of Russia’s state hi-tech corporation Rostec, will demonstrate at the St. Petersburg naval show an Internet access system installed on the heavy nuclear-powered missile cruiser Pyotr Veliky and on Russian submarines and frigates, the Group’s press office reported on Tuesday.

    Ruselectronics specialists have developed an Ekran-TsM system that receives television channels and connects shipborne telecoms equipment to the Internet and can be used on surface ships and submarines of both the naval and civilian fleets, the company’s press office said.

    "The system currently operates aboard nine Russian Navy vessels, including on the heavy nuclear-powered missile cruiser Pyotr Veliky, the frigate Admiral Gorshkov and three nuclear submarines… The Ekran-TsM system will be demonstrated at the 8th International Maritime Defense Show," the press office said in a statement.

    According to the Ruselectronics data, the system provides for the reception of any television channels through a satellite communications channel, including both free TV channels from among state multiplexed packages (20 channels as of today) and channels offered by outside satellite operators through paid services.

    The 8th International Maritime Defense Show will be held in St. Petersburg from June 28 to July 2.

    Same Pantsir-M pics as above https://sdelanounas.ru/blogs/95261/
    Its being displayed at IMDS
    From the comments a brochure

    And comparison vs Kashtan:
    Kashtan / Pantsir
    1. The number of simultaneously engaged targets 1/4
    2. Reaction time, with 6-8 / 3-5
    3. Range, Missiles, 1.5-8 km / 1.5-20
    4. Height Missiles, 5-3500 m / 2-15000
    5. Range, art. arms, 0.5-4 km / 0.5-4
    6. The height art. arms, 5-3000 m / 0-3000

    Rostec Introduced The Newest Marine Anti-Aircraft Complex "Pantsir-ME"
    Here: http://rostec.ru/news/4520583

    "One of the key imperatives of the cluster strategy of" armed "state corporation Rostec is the development and creation of new weapons, including the segment of anti-aircraft missile systems. Development of the "Pantsir-ME" complex is a logical element of the strategy. Create virtually every major complex systems require a fundamentally new scientific and technological solutions. As a result, the potential of striking complex "Pantsir-ME" has increased three or four times in comparison with the complex "Kashtan-M", - said General Director of the State Corporation Sergei Chemezov Rostec.

    Thus, the affected area surface-to-air missile is increased from 10 to 20 kilometer range and from 3 to 15 km in height. All stages of the combat work - from search target before firing - are carried out in motion. The combined use of radar and optical control system provides all-weather capability and vsesutochnost his work. All processes are automated complex, the crew only provides monitoring and control.

    High efficiency defeat PKR achieved through features embedded in SPAR "Pantsir-ME." Saved modular design of the complex: a command module and up to four combat units, depending on the ship class that allows you to build his defense flexibly. Combined Artillery missile arming provides effective engagement of all target types in the entire range of their operational use conditions, means and methods for counteracting from the perspectives of development up to the 2020-2025's.

    Use in combat module complex "Pantsir-ME," Multifunction radar with a phased antenna array and the surface-to-air missile with a range of 20 km provides simultaneous firing four goals, as well as the defeat of the new types of small and upgraded ASM means of air attack and surface targets. Combat unit can work both independently and as part of the four modules of the battery. The complex may be placed on vehicles with a displacement of 300 tons.

    They already tested a new missile with 40 km range. It's probably for Pantsir-M, the question is if already build pantsirs could fire it ?

    Nice picture BTW. I tough the pantsir would take much more place than Tunguska/kashtan on ships, but it seems it fits in the same place.

    It gives a true power-up to small ships because the kashtan was more like a double Hard kill system (guns+missiles) while Pantsir is more a medium range system with hard kill capabilities. It can protect an entire fleet from missiles when mounted on a small karakurt while the S-400 and redut equped ships can protect higher altitudes and ranges while being behind the Karakurt. Something like what we see in ground air defences.

    A nice thing to do would be to integrate it to submarines in a retractable system (it could fit in a bulava luncher), specially in the north were they could found unprotected P-8 and shoot them from 20 km.

    Nowhere to Hide: Russia Unveils New 'Hovering' Anti-Submarine Bomb

    Russian defense manufacturer Techmash presented a new guided anti-submarine munition at the ongoing International Maritime Defense Show 2017 in St. Petersburg.

    During the International Maritime Defense Show (IMDS) 2017 that launched in St. Petersburg on June 28, JSC Techmash, a subsidiary of Rostec Corporation, presented its latest creation: Zagon-2E – a unique ‘hovering’ guided anti-submarine bomb.

    What really sets this munition apart from its analogues is its ability to "hover" over the water’s surface for up to four minutes, according to a statement issued by Techmash.

    The bomb has a target detection range of up to 450 meters, and is designed to be used against both surfaced and submerged submarines, with the latter including vessels operating at periscope depth or lying on the seabed.

    It should be noted that the bomb's effectiveness is almost three times greater than that of its predecessor, the Zagon-1E.

    Shkval guidance?

    Post  KnightRider on Thu Jul 06, 2017 7:25 am

    I was looking into the Shkval, and had heard it was unguided. However, these pictures show some kind of connector on the rear right side of the torpedo. Is this an indication that the Shkval utilizes wire guidance from the launching submarine, or is it something else?

    I think its got a limited inertial guidance so that might be where the course gets programmed?

    That's what I would think, but is there any way to tell definitively whether it's that or some sort of wire guidance? I tried searching Google images for rear-facing pictures of other Russian torpedoes to compare the connector on the Shkval with the wire guidance connector on them, but I couldn't find any.
