    Sure, and I freely admit I'm well over my skis here, but still, kevlar is a polymer/fiber.

    I'd assume we could find ways to 3D print fibers which offer rudimentary ballistic protection and overhead cover against frag, if not high calibre rounds, which is the menace here, not to perfectly replicate  cement and steel.

    Truck the hollow lego brix to the front, fill 'em with dirt like a sandbag, etc. Quick 'n dirty!  The most urgent need here though seems to be decent overhead cover for foxholes. with prefab hatches to keep drones from flying in. Etc.  Just saying that this IS the kind of stuff the remaining non-Chinese industrial base can still crank out in bulk, real fast....

    ...Search '3D printed bunkers' and you'll find stuff that purports to be structurally sound enuff to bury.

    P.S. I don't know what the thermal/masking properties of these plastics are, but ability to install a LOT of these also seems helpful.... dummies, fallback positions, etc.

    @Kinophile

    Why bother with 3d printing? Its not faster for plastics than just stamping out forms. Would it not be easier to just create a mold (costly, sorta slow) and then just stamp out standerized bunker shells using heavy duty plastic mixed with kevlar? Once you get a floor line going it could complete hundreds in a day, using that one mold. 

    These could form the basic interiors and act as the internal formers for rebar concrete poured over them in-situ. A further liner inside to catch shrapnel/flakes from impacts would help. 

    3D printing has certain applications but its hard to beat the 10,000 year old concept of simple molds for just rapid, fast production using basic materials. Way less moving parts, for one!

    3D printed ballistic materials could offer significant breakthoughs - but I suspect we're quite a while away from beating the layering system of kevlar on cost & time.

    It's because the attack was all directed on Kyiv with strongest AD shield in Ukraine. If each city had the same protection, the total result would be like this.

    It was at 5:00 I heard two Patriots launches, then heavy boom so windows shaken. It was Kinzhal or Iskander interception - it came from NE direction, were my district is located, so interception of ballistic missiles add some adrenaline %) Then, since 5 minutes one more (aero)ballistic target was destroyed, but slightly further. Then I heard 2-3 distant booms - all other missiles flew from western direction and were intercepted there - it's too far from me. 

     But anyway, several Kh-101 were intercepted over the city and hit the ground in residental areas  - 12 citizens were wounded. Damaged several buildings, one workshop, kindergarden, church, local power substation. Several cars burnt. 

    Here fragment of missile impacted on the street not far from one of specific object %) and damaged buildings around - probably warhead detonated. 

     

     

    Here of course "underground command bunker was destroyed" )))

     

    People of this house were really lucky...

     

    ... Because warhead of intercepted Kh-101 fell down directly near the building and didn't explode

    Немає опису.

    Of course, Russian MoD made a statement "the strike, including Kinzhal missiles was performed on decision making centers - all targets were hit". Ok. 390 millions USD to nowhere. Rich country...

    I do have concerns about why RUS is launching such a large wave now.

    There have been consistent reports of dwindling AD supply. Patriot supply is in doubt (hello, Mr. Spineless Speaker) and several of these large waves, if repeated over, say, a two week period could rapidly eat into the existing stocks. Targeting Kiev could pull Patriot supply (but not necessarily the launchers) away from the forward zones. Once the Patriots are are used up then Kiev would be essentially defenceless to such waves. Such a surge followed by a burnout of AD could be a serious strategic and operational win for Russia.

    Counters to this worry are:

    1. We don't know just how many PAC-3 UKR have - but nothing is infinite.
    2. We don't know if Patriot resupply is being covered in other ways (eg through Allies)
    3. Ukraine has developed long range strike capabilities - if they're able to hit refineries 1,000km away, what's to stop them striking RUS bombers on home airfields? Oh wait, they're already at it :)

    The links are broken for me but I am very skeptical about building  bunkers with 3d printing - and I say this as someone who designs structures, sometimes against explosions. If plastics are involved multiply that by 10. 

    Fully agree, ref plastics. I think most proper structural 3D printing is focussed on other materials - concrete mostly but I've also seen liquified wood products. 

    3D printing is fantastic for shaping a form so its the darling child of modern architects for designing (speaking as a former architect). Engineers, in my experience, are usually a lot more circumspect - not because of ignorance or inability to see the possibilities but simple realities of physics and materials science. 3D printing does many things but not certain things. A gain somewhere (e.g. a hyper-parabolic wall built quickly) has a cost somewhere else (structural integrity under dynamic stress loads).

    Everything is a trade-off, physics isn't free.

      I don't think there's been a significant impact on its maritime capacity reported by anybody.

     

    This is what I'm thinking about ref Seababies in the Black Sea.

    UKR could start sinking RUS Maritime trade, starting with ships carrying stolen grain. 

  5. Quote

    In the mind of a non-expert, a refinery full of highly flammable liquids can easily turn into a huge fireball. The reality is different. Russian construction codes—a relic of the Cold War—make refineries resilient against traditional air bombing. And they usually have plenty of firefighting equipment available. This means drones cannot destroy a whole refinery. They can, however, create a fire. And if they are lucky, managing to hit a gas fractionation unit, they may even be able to cause a bigger explosion.

    After both the recent attacks, resulting fires were extinguished within a few hours, and the damage was successfully contained. It’s likely that the Ust-Luga and Tuapse refineries will be able to immediately resume operations, albeit with reduced throughput and limited product slate. Under normal circumstances, a full repair would be expected to take no more than a couple of months.

    However, the circumstances in which the Russian refining sector finds itself at the moment are far from normal. When Russia began rebuilding its industrial base in the early 2000s, the country largely used imported equipment. As it gradually integrated into the global economy, Russia was able to purchase many different kinds of machines—far more than the limited selection produced in the Soviet Union. This came to an abrupt end in 2022, when the full-scale invasion of Ukraine destroyed the globally integrated model.

     

  6. To be clear, Im not quite buying his argument here. 

    It's possible (no drone) but I'm put off by two factors - his insistence on naming Photoshop as the editing tool (Premiere Pro and After Effects are the right tools), and shutter speed.

    PS can be used certainly, but it's comparatively labourius and awkward. AE and PPro are tightly integrated and much more flexible - they're designed to work together. If you have PS then you have PPro and AE - they all come with Adobe Creative Content as a single subscription. Why bother using PS if you have PPro and AE right there? Lack of this basic knowledge on his part gives me pause but is not a definitive point. 

    Using a drone would be very easy, but they're are by now many RUS operators capable of doing this attack from a decent distance. Why bother not using one?

    In the same breath it's even easier to use a basic drone with no payload, fly it into frame and then scrub it in the timeline before it gets too obvious that it's not armed. The camera is locked so its very simple to scrub the drone out with empty frames - and anyone walking up to the helo as well.

    Its obviously a staged even (durr a fueled helo with missing windshield?) but I'm Not yet convinced by this argument of no drone. 

    There are some counters to my doubt. The major one is the last section he highlights and gives not a lot of time to, but which I personally view as a serious question:

     

    The dark smudge travels with the cloud, yet the following darker cloud has no such tailing smudge (so it's not a lensing artifact). The "gaseous" cloud overlays the helo yet that would put it out into the sunlight, out of the hellos shadow and a Camera like this simply wouldn't pick up that fine gas. Also the gas would go out, and to frame left more than towards camera. It feels additive, ie a visual effect added in post. I even bet that one could find that exact explosion effect in some commercial VFX library. 

    TLDR I suspect there was a drone, but it was unarmed. I suspect the helo was bombed manually and the explosion,  though real, has been visually augmented with a preceding "explosion" that is actually a stock video file of a studio-shot VFX asset.
