    Pulling out of the INF treaty is a big step so I think they should keep that card as long as they can.

    On paper the introduction of S-400 and S-500 should allow a wide range of ballistic missiles to be defeated including pretty much all those weapons in the IRBM range class so the INF treaty really would become redundant, but considering it is an agreement between the US and Russia and on paper the US has no reason to make such weapons just to engage Russia, while Russia has plenty of Intermediate range targets that could be much more efficiently targeted with shorter range weapons a change needs to come at some stage.

    A couple of missiles slightly bigger than Iskander but with a 2,500km range would be very interesting... Scramjet powered missiles are another option too.

    I am pretty sure quite a few countries would spend billions on such products...

    reactions from Poland would be fun, but I don't think the west would understand that this was their fault... the result would be another pointless expensive arms race...

    Are you serious?

    If there is a critical need to rapidly produce some fox holes or firing positions they might be useful depending on how effective the material they use is... I suspect not very.

    If Russia is going to the moon and they take some big 3D printers to mix moon dust and water to make buildings like mud buildings on earth then it might make sense, but complex layered armour structures are likely too difficult to create with a 3D printer and the printing materials they use.

    The concept is good for a printer to be taken where the print media can be found already and processed through the printer to create the 3D object, but if you have to take the high strength materials with you... you might as well make it properly and take the completed item.

    I doubt a tank could be printed properly as its armour would likely be weak, while all its complex electronics would need to be added to the shell....  like I said... simple homes OK, complex vehicles... no.

    Compared to any American build house this 3D printed china made houses are luxus.

    Americans build their houses made of plywood, you can crash the entire house with your fists, each wall made of plywoods, not a single brick. The strongest segment of american made houses are the Door frames.

    Let's not get carried away here. I'd rather have a more un-biased discussion.
    I've lived in America for some time, and it's not bad housing materials that's their problem right now, it's rather their economy, the Kleptocrasy that most Americans despise, their hypocritical foreign policy that makes many nations hate them, their blind support for oppressive regimes, their moral bankruptcy, their decadence and their apathy, the consumerist populace, etc. Many problems to solve that have the priority before the building materials, which by the way, aren't bad at all.

    So?!
    The English have build theirs with clay and straw, and they're still standing after many centuries.
    We've had mostly stone houses throughout our history, that now lay in ruins in many of our abandoned villages.

    Anyway, enough of that.

    On the point of building military machines with massive 3D printers, I don't think that 'll work. For the reasons that were stated previously. The only way to use a 3D printer for military technology at the moment is to make molds for parts, which I think the Russians already use. At least I hope they do.
    It's not a bad idea per se, it just not within tech reality at the moment. But this definitely doesn't mean that they should not do R&D on this and might turn out to be a good project.

    The only way I can think of to make a decently protected vehicle using a 3D printer would be some sort of resin based material that becomes a super strong plastic when its components are mixed.

    For very light vehicles steel can become ineffective because using very thin sheets of it makes it weak, but using a strong plastic that is 30 times thicker but weighs the same can be made stronger. ie say for example you have a sheet of steel 2mm thick that weighs 5kgs per square metre. For the same weight you might be able to use plastic material 60mm thick that would be much stronger structurally and more resistant to bending or impacts... that could be printed rather than built as pieces and assembled.

    Problem is that to print it, you need to liquefy it, which means a HEAT round would cut through it like a hot knife through butter...

    Worth the effort . It is essential to remember a couple of things about mitigating the effects of severe blast waves on vehicles  .

    First it is not really an energy absorbing problem or energy redirection problem. There is a HUGE amount of energy in say one pound of TNT, let alone the typical anti-vehicle landmine or IED. As for the human, anti-personnel landmines are severely injuring the lower extremities more so that the torso .

    What is truly occurring in mitigating blast effects on vehicles is an Impulse transfer extension of time (spread the impulse over time to reduce the peak acceleration) and reducing the resulting surface pressure by reducing the "Reflection Factor" that occurs when a blast wave impinges on a structural surface.

    For example, in "ideal" air the reflection factor can be as large as eight . Therefore, a 1,000 psi impinging blast wave could induce almost an 8,000 psi surface pressure on the structure. Except, in a typical landmine "non-ideal" atmosphere (air mixed with the products of detonation) reflection factors as large as fifteen (15) have been measured (via transferred impulse.

    What is transferred impulse? How high does that 15,000 pound vehicle's CG jump? That is directly related to impulse.

    Those high reflection factors are measured against structural surfaces that do not move appreciably during the blast loading. Given that the blast wave almost always has a duration of less than a millisecond, even the motion of the structure is not enough to alleviate the peak reflected (surface) pressure. Yet, a crushable core in a sandwich construction, will cause the front surface to move (appreciably) during the loading and reductions of surface pressure in excess of twenty-five percent have been measured, as well as the spreading the acceleration profile.

    A several pound equivalent TNT detonation would require a few Inches of movement during the loading phase. Your liquid filled tubes do not provide that much motion before the front face will "bottom out".

    Also, these blast attenuation techniques must survive storage temperatures that by  range from minus 65 deg F to positive 220 deg F. That is an extreme range for most liquids, without freezing or boiling.

    Ergo , whatever technique you come up with , your technique should provide some level of blast induced response amelioration.

    Whether that amount of reduction is sufficient or cost-effective is the proof that you and your product must provide, throughout the Operational temperature extremes of -40 deg F to +180 deg F (as compared to the storage temperatures).

    Look's like the cost of manufacturing Ak's will drop by a significant margin, producing parts for Ak's will drop by a whopping 40%:

    Kalashnikov" buys 51% stake in the group "Synthesis-PD"

    The transaction cost of production parts drops by 40%

    Concern "Kalashnikov", belongs to the State Corporation Rosteh buys 51% stake in the group of companies "PD synthesis" - the only Russian manufacturer of metal products for MIM-technology using raw domestic producers.

    Amount of the transaction, the financing of which concern implement their own and loan funds, is more than 250 million rubles. It is assumed that it will be closed until the end of June 2014.

    "Partnering with" PD synthesis "is an important step in the modernization of production enterprise. Now 90% of the parts produced and refined manually. Using old technologies that are serious time and effort. Thanks to the experience of "Synthesis PD" we will be able to halve the time of the manufacture of parts and reduce production costs by more than 40%, as well as improve quality characteristics and increase production, "- commented CEO deal of concern" Kalashnikov "Alexey Krivoruchko.

    "Synthesis-PD" specializes in the manufacture of metal products for MIM-technology (from the English. Metal Injection Molding), ie by injection molding.  This technology is used as raw granulated balanced mixture of fine metal powders and polymer binder, which is called feedstock.

    With MIM-technology can manufacture parts weighing up to 100 grams in weight term may be increased to 400 g

    Attracting new partner will allow the concern to change the approach to the design of new products. Current technology does not allow for sophisticated design details to the extent necessary, it inhibits technological progress and makes it impossible to integrate the production of new engineering developments. Thanks MIM-technology, manufacturing of parts of any complexity takes a minimum of time and gives maximum precision in execution.

    According to Вестник Мордовии, Koalitsiya-SV uses microwave propellant initiation.

    This also indicates that various Koalitsiya variants are not intended to be compatible with Giatsint type of guns. Of course, it was never expected that there would be any compatibility with the Msta type of weapons.

    I don't recall seeing this posted before.

    BTR variant with one of the new remote weapons stations. I think it's designed for the anti-sabotage roll for the nuclear forces.
