   So this thing was supposed to have autoloaded 76 mm (?) AC, and 2 ATGMs on top turret... with 4 RCWS, 2 of them armed with AGLs and 2 with 7.62 GPMGs. That is rather hot load for IFV by early 90s standarts. Although second variant had 8 dismounts, while first was for 11 (?)

 

...and let's not forget what appears to be 4 portholes, 2 on each side - I guess that's what those 2 rectangular holes at the back are intend to portray.

   Yeah, i know. Those things looks a bit unnecessary when this vehicle have like 4 RCWS and main weapon system.

btw, it's on par with soviet late 80s BMPT (Obj.781 Sb.8).
Overall, 299-based HIFV looks just like BMPT-as-it-should-be (in case one thinks of it as of BMP-T, aka IFV-H, still retaining distmountable infantry)

I guess it looks better in tablechart - when one proposes IFV with 8 so-called "active dismounts" instead of just 4.
With just 4 - it would be on par with some pity old version of Mowag Tornado from early 60s

Going back to 2014 posts in this thread, but are any internal layout diagrams of the Object 780 available? I'm most curious about how the driver's optics worked; does the gun not recoil far enough back into the turret to go between the driver and his optics, or is there some other arrangement that lets it work?

I believe the "gun" is just a missile launcher, or it only fires low-impulse HE rounds at the most.  So the breech should be quite small, and the recoil path quite short, so the driver can fit behind it.

   Some info about Soviet 70-80s MBT project with 2 cannons was posted on Andrey's site. Here is a picture:

Ohh, sorry, here is a picture:

   Tank with 2 guns (490 "Poplar")

 

   A project from 80s of a tank with maximum protection, firepower and crew safety. One of the most unusual developments of the Soviet tank construction in the post-war period was the project of a two-cannon tank by Evgeny Morozov. The works were carried out in the late 70s and were presented to the customer along with other possible directions for the development of the layout for the future tank.

 

   Among the proposed options were also considered:

- turreted tank with two operators (490 option 1 [was posted here as Object 490 Topol'])

- non-turret tank (with limited [gun] traverse/arc)

- articulated (two-link) tank

- tank with external weapon mounting system.

 

ÐвÑÑпÑÑеÑнÑй Ñанк (490 «ТополÑ»)

 

Quote

   The layout of the tank was unusual, the hull was divided into isolated compartments, the first - the transmission compartment, the second - the fuel compartment divided by partitions, the third - the engine compartment. The crew consisting of two operators was placed in the rear of the hull in an isolated stationary capsule.

 

   The capsule was fixed, the crew in any position of the turret, was facing frontl, the rotation of the turret with the main armament was carried out around the capsule. The "turntable" with the main armament had a powerful frontal armor, on the sides 125 mm guns of increased power were installed, or 130 and 152 mm guns that were under development at the same time.

 

   Ammunition consisted of unitary shots placed in two autoloaders with a simple scheme located in the compartments behind the guns, which were fed from the horizontal ammorack. With the damage/hit of the compartments and fire (detonation) of ammunition, the likelihood of the destruction of the tank crew was excluded. With the damage of one of the compartments with gun and autoloader, the tank retained the ability to fire.

 

   The second turret was located above the capsule, it had the sighting system of the commander-operator and driver, a static view device and a RCWS, which included a stabilized 23 mm R-23 cannon and 7.62 mm machine gun.

 

   The chassis of the tank is made using a number of units of the Izdelie 219 and consists of six pairs of rubberized support rollers. There are guide wheels in the back of the tank, leading wheels in the front. During salvo firing from ambush, the guide wheels are lowered to the ground in order to impart greater stability during firing. Adjustable hydropneumatic suspension. Engine - product 29. Transmission - electromechanical or product 29G (1250 hp).

1 - operator's seat (when the tank is moving in reverse);

2 - emergency hatch;

3, 5, 13 - radiation protection, heat and sound insulation:

4 - a set of organs and instruments for controlling fire and motion;

6 - a device for monitoring and controlling weapons;

7 - a static-type device for viewing (8 pcs.);

8 - turntable/turret;

9 - hatch for entry and exit of the crew;

10 - reversible viewing tube;

11 - position of the operator during rest;

12 - tank hull;

14 - operators chairs

What sort of auto-loader did the Object 490A have? Was it isolated from the crew compartment?

   First page of this thread:

img006.jpg

About half of volume under Object 490A's turret was an autoloader. And from here (http://btvt.info/2futureprojects/490a.htm):

Quote

Mechanized ammorack occupied the right side of the fighting compartment. The shots were placed horizontally in 5 rows. The crew was separated from the elements of the loading mechanism by a partition.

 

   I probably should update first page with additonal info and new models/pics.

Object 195 model in AW. I have questions to about half of this model - where they got idea that some parts are exactly like they are modelled (i suspect they just guessed).

      This shall be the general thread for all things soviet tanks. I shall start by posting an article I just wrote for my blog. I would recommend Archive Awarness which is an excellent blog about Soviet tanks and their experiences with other nation's tanks.

      T-14 ARMATA 
      (edited)
              This thread is about glorious russian MBT T-14, known as "Armada", "T-95", "black eagle", "T-99" and other stupid Western names given to Object 148 (T-14 in some recent documents). Here is number of images connected to that vehicle.
       

      Official model of unknown "artillery vehicle". Yeah, Putin, we know that this is T-14. Note Gatling gun on turret right side.
       
      Artist impression of T-14 based on known model, by Fyodor Podporin. 
       

      T-14 will use Relikt ERA, which is considerable improvement over Kontakt-5 in resisting to tandem HEAT warheads and EFPs.

       
      Side skirts would be thicker on a real vehicle, i think. Relikt have AFAIK bigger size than Kontakt-5 ERA build-in blocks.

       
       
       
       
       
      Whole album with renders: 
      http://imgur.com/a/8Tn9b
       
      Video of same render from same artist:

       
       
            People expect that tank would have turret weapon system like what you see on the BMP-3 "Bakhcha-U" turret - a lot of weapons in one turret for one gunner to work with. T-14 is rumored to be equipped with 30 (or even 57) mm autocannon, 4-6 barrel gatling type MG/HMG, new 125 (2A82) or even 152 mm (2A83) smoothbore cannons. Turret is unmanned, crew of 3 would be located in frontal part of hull, behind very serious frontal armor inside of compartment, well protected from all directions. Cannon would be loaded by new autoloading device. I hope that Burevestnik is working on them, those guys managed to make 100 mm Naval gun with RoF of 300 shots per minute.
       
            I really like how turret looks, but i don't understand why there is such a big turret "busket" for unmanned turret with all ammo placed inside of hull in special armored housing. Also, i don't see gunner sight and proposed FSC radar on 3D model (i assume that panoramic sight is for commander). Laser sensors on 3D model are from T-90A variant of "Shtora".
       
            Some officials mentioned works on new active protection system, that consist of powerfull radar station, that can work on "long ranges" and engage incoming projectiles (missiles) with that gatling MG. Will this system survive development stage and be presented on serial tanks is unknown. Although turret for T-15 Armata-based IFV already was shown with new APS "Afganit".
       
            If you pay attention you may see that artist used T-80 rollers for Armata chassis, and this is not a mistake - according to some sources Armata heavy chassis will use T-80 or T-80-like rollers to save weight. And looking at rear part of that tank you may notice a engine deck from gas-turbine equipped version of the T-80, which can be mistake becuase MoD want Armata with new ~1500 HP diesel engine.

      At the end of January, 2018 and after many false starts, the Russian military formally announced the limited adoption of the AEK-971 and AEK-973 rifles.  These rifles feature an unusual counterbalanced breech mechanism which is intended to improve handling, especially during full auto fire.  While exotic outside of Russia, these counter-balanced rifles are not at all new.  In fact, the 2018 adoption of the AEK-971 represents the first success of a rifle concept that has been around for a some time.

      Earliest Origins


      Animated diagram of the AK-107/108
       
      Balanced action recoil systems (BARS) work by accelerating a mass in the opposite direction of the bolt carrier.  The countermass is of similar mass to the bolt carrier and synchronized to move in the opposite direction by a rack and pinion.  This cancels out some, but not all of the impulses associated with self-loading actions.  But more on that later.

      Long before Soviet small arms engineers began experimenting with BARS, a number of production weapons featured synchronized masses moving in opposite directions.  Generally speaking, any stabilization that these actions provided was an incidental benefit.  Rather, these designs were either attempts to get around patents, or very early developments in the history of autoloading weapons when the design best practices had not been standardized yet.  These designs featured a forward-moving gas trap that, of necessity, needed its motion converted into rearward motion by either a lever or rack and pinion.
       

      The French St. Etienne Machine Gun
       

      The Danish Bang rifle
       
      At around the same time, inventors started toying with the idea of using synchronized counter-masses deliberately to cancel out recoil impulses.  The earliest patent for such a design comes from 1908 from obscure firearms designer Ludwig Mertens:


       
      More information on these early developments is in this article on the matter by Max Popenker.
       
      Soviet designers began investigating the BARS concept in earnest in the early 1970s.  This is worth noting; these early BARS rifles were actually trialed against the AK-74.
       

      The AL-7 rifle, a BARS rifle from the early 1970s
       
      The Soviet military chose the more mechanically orthodox AK-74 as a stopgap measure in order to get a small-caliber, high-velocity rifle to the front lines as quickly as possible.  Of course, the thing about stopgap weapons is that they always end up hanging around longer than intended, and forty four years later Russian troops are still equipped with the AK-74.

      A small number of submachine gun prototypes with a BARS-like system were trialed, but not mass-produced.  The gas operated action of a rifle can be balanced with a fairly small synchronizer rack and pinion, but the blowback action of a submachine gun requires a fairly large and massive synchronizer gear or lever.  This is because in a gas operated rifle a second gas piston can be attached to the countermass, thereby unloading the synchronizer gear.

      There are three BARS designs of note from Russia:

      AK-107/AK-108
       


      The AK-107 and AK-108 are BARS rifles in 5.45x39mm and 5.56x45mm respectively.  These rifles are products of the Kalashnikov design bureau and Izmash factory, now Kalashnikov Concern.  Internally they are very similar to an AK, only with the countermass and synchronizer unit situated above the bolt carrier group.


       

      Close up of synchronizer and dual return spring assemblies

      This is configuration is almost identical to the AL-7 design of the early 1970s.  Like the more conventional AK-100 series, the AK-107/AK-108 were offered for export during the late 1990s and early 2000s, but they failed to attract any customers.  The furniture is very similar to the AK-100 series, and indeed the only obvious external difference is the long tube protruding from the gas block and bridging the gap to the front sight.
       
      The AK-107 has re-emerged recently as the Saiga 107, a rifle clearly intended for competitive shooting events like 3-gun.
       

       
      AEK-971

      The rival Kovrov design bureau was only slightly behind the Kalashnikov design bureau in exploring the BARS concept.  Their earliest prototype featuring the system, the SA-006 (also transliterated as CA-006) also dates from the early 1970s.



      Chief designer Sergey Koksharov refined this design into the AEK-971.  The chief refinement of his design over the first-generation balanced action prototypes from the early 1970s is that the countermass sits inside the bolt carrier, rather than being stacked on top of it.  This is a more compact installation of the mechanism, but otherwise accomplishes the same thing.


       

      Moving parts group of the AEK-971

      The early AEK-971 had a triangular metal buttstock and a Kalashnikov-style safety lever on the right side of the rifle.



      In this guise the rifle competed unsuccessfully with Nikonov's AN-94 design in the Abakan competition.  Considering that a relative handful of AN-94s were ever produced, this was perhaps not a terrible loss for the Kovrov design bureau.

      After the end of the Soviet Union, the AEK-971 design was picked up by the Degtyarev factory, itself a division of the state-owned Rostec.



      The Degtyarev factory would unsuccessfully try to make sales of the weapon for the next twenty four years.  In the meantime, they made some small refinements to the rifle.  The Kalashnikov-style safety lever was deleted and replaced with a thumb safety on the left side of the receiver.


       
      Later on the Degtyarev factory caught HK fever, and a very HK-esque sliding metal stock was added in addition to a very HK-esque rear sight.  The thumb safety lever was also made ambidextrous.  The handguard was changed a few times.



      Still, reception to the rifle was lukewarm.  The 2018 announcement that the rifle would be procured in limited numbers alongside more conventional AK rifles is not exactly a coup.  The numbers bought are likely to be very low.  A 5.56mm AEK-972 and 7.62x39mm AEK-973 also exist.  The newest version of the rifle has been referred to as A-545.

      AKB and AKB-1


      AKB-1


      AKB


      AKB, closeup of the receiver

      The AKB and AKB-1 are a pair of painfully obscure designs designed by Viktor Kalashnikov, Mikhail Kalashnikov's son.  The later AKB-1 is the more conservative of the two, while the AKB is quite wild.

      Both rifles use a more or less conventional AK type bolt carrier, but the AKB uses the barrel as the countermass.  That's right; the entire barrel shoots forward while the bolt carrier moves back!  This unusual arrangement also allowed for an extremely high cyclic rate of fire; 2000RPM.  Later on a burst limiter and rate of fire limiter were added.  The rifle would fire at the full 2000 RPM for two round bursts, but a mere 1000 RPM for full auto.

      The AKB-1 was a far more conventional design, but it still had a BARS.  In this design the countermass was nested inside the main bolt carrier, similar to the AEK-971.

      Not a great deal of information is available about these rifles, but @Hrachya H wrote an article on them which can be read here.

      Something I haven't seen discussed on this site before; Soviet/Russian efforts to domesticate foxes by breeding for domesticated behavior. Article in Scientific American here; https://blogs.scientificamerican.com/guest-blog/mans-new-best-friend-a-forgotten-russian-experiment-in-fox-domestication/
       
      Interesting that there were physical changes correlated with the behavioral changes the Russians bred for.

       
      Buy one for only $7,000! https://domesticatedsilverfox.weebly.com/aquiring-a-tame-fox.html
       

      (not entirely unlike a dog I guess)
       
       
      It seems like a pretty cool idea to drunk me, though I don't have a spare 7,000 dollars laying around (thanks student loans!). Also, I don't think my cat would approve.
