you wil never get rid of the tank or its rounds we have so much DU. and after seeing the war in Ukraine we see the need more and more. because as you can see Russia has ran out of smart bombs nearly. noting beats a hard dart. and the army has just changed to a new round that drops the round type count down to 2. DU and a new HE type that's just bad ass. DU is only needed vs tanks so they made this round./

1:30 "[..]Uranium. The heaviest, naturally occuring element on earth" Nope. Tungsten is heavier by a little more than 1% (Naturally occuring Uranium is lighter). Gold, platinum, indium and osmium are even heavier, but Gold is the cheapest one of these four. You would bankrupt your entire army by ordering a few rounds of those. It's not that DU is cheap, it's actually that it is rather useless. Tungsten has a wide applicability in machine tools, so it has some intrinsic value. That makes DU the perfect alternative for when you have cheap dead weight that does not accupy much space, like aircraft ballast and trim weights. Natural uranium has a 0.77% of fissionable uranium. Reactor designs vary, but you have to crank that percentage up to turn it into fuel rods, the most being 3% Uranium 235. You have to extract that 0.77 from more uranium, depleting it of it in the process. In the end, for every kg of reactor fuel (3% enrichment), you end with about 4kg of DU. For weapons grade uranium, every 1 kg of 80% pure uranium leaves you with about 104Kg of DU. The Little Boy bomb design built in Hiroshima had 64kg of Uranium enriched to an average of 80%. The US built 26 of them. And that was only the very first design they "mass produced". The way they do it is through Isotopic Separation. The uranium enriching process involves turning natural Uranium into Uranium fluoride (UF4), a fine yellow powder known as "yellowcake". You take that powder and throw it into a centrifuge. Much like Plasma separating from blood cells in medical centrifuges, uranium centrifuges make the heaviest elements go to the outer casing of the centrifuge drum whereas the lightes ones stay in the center. But there's so little of the slightly lighter U235 compound they have to scrape off the outer layer of the thing and repeat the process over and over and over again until you end up with the desired concentration. Industrial scale uranium refining involves scraping off most of the powder from the inside of the centrifuge and sequentially throwing it into the next, each step containing more and more U235. For reactor grade uranium, dozens of centrifuges are used. For weapons grade (80% and up), the number of centrifuges running, each scraping off that little bit more of U235, numbers in the thousands. As stated above, Depleted Uranium is indeed rather useless. There have been some developments in it's use as fuel in the MOX and Breeder cycle, but their use involves plutonium, and you know, no proliferation and stuff. The alternative is developing the Thorium Fuel cycle that turns U238 in U232 withouth going through Plutonium, but I don't know how close to a practical reactor we are (India is investing heavily in it, though). Using it in ammunition or armor was only natural. Because it's heavy weight favors it as a cheaper alternative to Tungsten. It was then when the "self sharpening" property was discovered and the use proliferated through nuclear capable countries. Some countries, like Germany itself, insist in using Tungsten penetrators still. The Dart KEP round is not good because of the Uranium. It is a good design by itself. Projectiles have a measurement taken into consideration when you want to design them for penetration, not only through armor, but through flesh and air as well. It is the Ballistic Coefficient, which is basically a relationship of the length and the diameter of the projectile. You can see it as a bunch of mass trying to get through the same hole. It's easy to picture that a dart will have a much easier time getting through a flat piece of steel than a ball, right? That's, in simple therms, because there's a lot more mass carrying momentum behind the tip of the dart rather than spreading it out like the ball. That stream of thought is what made them design a "dart" as a kinetic energy penetrator for tank guns, known as a Long Rod Penetrator. The concept has been applied since the T-62. And finally, a topic I think you broached briefly. Depleted Uranium is, by itself, pretty much harmless. You can handle them all day and carry some in your pocket withouth deviating from the mean chance of Cancer in the general population. DU still has some leftover U235 in it, but overall it's pretty inert. It's half life is like 4.5 billion years (that's almost the age of the Earth itself...), meaning it is still radioactive, but releases it's energy sooooo slowly it's pretty much harmless. In fact you'll be exposed to more radiation in an 8h flight than by sitting all day in a DU ammunition storage shack. DU is actually used as radiation shielding, and it's better than Lead at it. The health concern with it is not the practically nonexistent radiation, but rather because it is still a heavy metal, very much like lead in that regard. The controversy about DU rounds it's because their impacts pulverize the projectile and creates a fine heavy metal dust that can be inhaled. And one final note, about the monocristalinic thing people get wrong all the time. Even prof. Martyn Poliakoff (from Periodic Videos) got that wrong, and I too was taught that wrong until I studied Engineering an actual expert in the matter taught me otherwise. You said in 8:08, It is not the monocristalinic nature of a material that makes it strong. Get that out of your head. It's the other way around *The finer the grains in a metal, the stronger it is*. This is due to the way the crystals are arranged. They form an homogenous, orderly crystal, so if you have "large metalic crystal" *that's the weakest it can possibly be*. Materials do not break by severing the atomic bonds with eachoter, but rather by atoms sliding off one another. This is the Sliding Planes theory, and if you look deeper into material science, you'll see this orderly structure crystals arrange themselves in has a ton of sliding planes. When a piece is made out of a mess of tiny little crystals, that means that there's a tangled mess of these sliding planes a crack has to go through. As the atoms on a crystal slide off one another, rather than going into a single direction as they would in a monocristalinic piece, they have to change directions as the orientation of the cristaline structure (the sliding planes) of the next crystal is totally different. *This is why the finer (and the more there are) "chaotic mess of tiny crystals" is much stronger than a monocrystaline piece!* I would recomend R. C. Hiebbler's Mechanics of Materials if you want to learn more. That's a staple engineering book and the best one about it around. You may have reached that erroneous conclusion because jet engine parts are made of monocrystalinic pieces. And that's true. They have to be monocrystalinic because they have to be strong, right? Wrong. Turbine parts work at very high temperatures. And high temperatures tend to erase any work you try to do to refine the grain structure of a material, turning it into a single crystal. So to get that out of your head *turbines are monocrystalinic because they have to be designed at their weakest due to high working temperatures". There has been a lot of research done in this regard to alloying and how they affect the crystaline structure of a metal, which are especially important for high temperature applications. There's also vacancies, substitutive elements and other stuff that break the sliding plane thing and help make a material stronger, but this comment is already too damn long. I would only recommend you read some of Hiebbeler's book again if you want to learn about them.

Interestingly, the Germans with the same gun do not use DU. They use a tungsten mono-block penetrator. Given the possibility that Germans would be fighting on their own territory, they didn't want DU dust/shavings littering their countryside. What they lose of course is the dramatic incendiary behind armour effect (DU burns like a mad bastard when it gets super compressed). But there's no indication that German rounds are ineffective against the threat (Russian tanks).

g=32feet/s/s (acceleration due to gravity) Dart drop = 0.5 x g x t^2 According to @kirklamb3270 we can assume 7,500fps velocity. At this velocity, it will take 1 sec to go 2.286km (7500ft), and the dart will drop 16ft. Definitely not negligible. Even at 229m, the dart will drop around 2 inches. It's definitely not a laser, but the firing computer can easily calculate the drop if there is an accurate range finder (which there is). Assuming that the dart spins, the computer also needs to calculate the effects of precession and the Coriolis effect. That's a lot harder math, but easy enough for the computer. They also need to account for air friction and they probably have an experimental calibration factor taking into account air pressure and temperature. But the computer can handle all that.

My dad did work on the depleted uranium round. The shape is the trick. At high speed it makes a jet of melted metal at super sonic speed inside the tank hit. The thing turns into liquid and melts the target metal impacted, everything inside is shredded. The ammunition also is hit by high speed melted splash and helps to keep the suffering inside the tank on the short side. 😁

The depleted uranium dart used in tank rounds has been proven effective, and while there have been arguments about the “health or environmental impacts” we have to remember these darts are used only in a real war. In a real combat situation, a tank commander wants to know his or her tank is fully capable of engaging and beating an enemy. All war is brutal and harsh, and trying to tease out what is more humane or environmental when we talk of weapons of war seems to be idealistic. When this round was used in the first Gulf War, the results were stunning. In almost every engagement, the Iraqi tanks were blown apart or pierced. The very high velocity, high density and flat trajectory of this depleted uranium dart are huge advantages. Yes, it is harsh and the results would stun us, but this is why deterrence and diplomacy are always the best approaches.

For those wondering, DU shells are NOT RADIOACTIVE. The real danger is that it is a heavy metal (like lead and osmium) and is rather toxic to the human body as a result.

Just don't play the M1A1 Abrams mod that was added to Operation Flashpoint back in the day. Whenever you were fighting that tank, the turbine was so loud that you had to stop the tank, switch off the engine, communicate, then start it back up again and execute the plan. Yes, it was so bad that even with VOIP volume cranked up, you couldn't hear the other guy over VOIP... Suffice to say, the more silent diesel engine of the T90 became the mainstay vehicle of choice :D

One of the big reasons for using the smooth bore120 in the Abrams is that the 105 could only fire a limited number of combat SABOT rounds before the rifling started to rip out and the gun became useless. Can't remember exactly how many, but it was about what a tank could expect to fire in a good fight. Also at longer rangers (1500 meters? Been a long time since I was at The Armor School at Ft. Knox) you also had to start allowing for the round drifting to the right because of the projectile's spin. It was becoming obvious that the sights were getting better than the gun and that armor was getting thicker so it was time to upgrade.

Thanks, I understand DU rounds far better now. Well explained and good vid. I subbed.

As a retired nuclear engineer who spent a significant part of my career working with U, I suggest you re-think your comment about the toxicity of U. I'll leave it to you to look up the LD50 does of the various heavy metals. U isn't at the top. If it were, I'd have been dead a long time ago. So would a large numbers of infantrymen who went poking around in killed enemy tanks in the middle east and afghanistan. The two main reasons to use DU are a) We have a huge stockpile of the stuff and not much of anything to do with it. and b) unlike Tungsten and the other very heavy metals, U is easy to machine. The machining must be done in an argon inert atmosphere because the stuff is so flammable. The government and contractors machine it in large glove-boxes. A private entity who has only a small amount of machining to do can simply wrap the machine tool in plastic sheeting and feed in the argon. U is spoken of as pyrophoric but not really. Pyrophorocity is the property of a substance to spontaneously ignite and burn in air. Potassium or white phosphorous for example. Uranium, along with aluminum and magnesium, would do so except that as any of these metals sit in air, an oxide shield forms. Aluminum's oxide is so tough and tenacious that it isn't considered flammable. Magnesium forms a less tenacious oxide layer so that it CAN be ignited in air. Once lit, it burns to completion and not much short of a Class D fire extinguisher will extinguish the fire. U also forms a tenacious oxide layer but as it grows, the oxide layer separates into thin, very sharp (ask me how I know!) oxide plains that provide just enough protection to prevent spontaneous combustion. Try to do anything with it and the situation is much different. Chuck a chunk up in a lathe and start making a cut. The swarf comes off as strings of burning metal. Get the workpiece too hot and it too will catch fire. U will react to nitrogen to form uranium nitride. It'll strip the oxygen out of water molecules. It'll strip the oxygen out of the carbonate charge used in dry chemical extinguisher. It'll do the same thing to sand. Only a Class D extinguisher which consists of very finely powdered copper can do the job on a small fire. Bigger fires are allowed to simply burn out.

What I learned from this video: All tanks are considered beautiful. I feel I must agree. :-)

I was always wondering about this, thanks!

This round was developed by the Army's weapons testing lab at Picatinny Arsenal in NJ. The original dart had only three fins which resembled a 50's scify rocket and was stated to have a 1/2" drop at five miles. Further the nose of the dart had an approximately 1/64th inch diameter radius with a slight swail behind it an was reported to create a shock wave in front of the round that would begin to affect the armor, heat it up, several feet before it actually made contact with it. I don't know if this version of the round made it into production but this was in the report at the developmental stages of the dart. I hope this info is declassed by now as I only came by it from working for the company that designed and made the original plastic cover that was used to protect the dart from damage during shipment. I guess I'll find out.

Nice briefing! Provided a briefing similar to this back in 96', the refresher is great however, where is any discussion pertaining to the A2 Bradley and subsequent variants which employed the DU rounds? I'm an old 11 series MG and particular to the Bradley's in the 90's.

Finally!; a video that delivers. Ethical considerations aside, that was fascinating. To the point, well researched, plain language, not overloaded with technical wank.

On the basis of that I then Googled 'Rheinmetall Rh-120'. The pretty pictures contained within the vid caused me to pause the vid and study the pics and the reasons for DU. Those pictures graphically (literally and figuritively) illustrated the fin stabilized smoothbore DU projectile. The ballistic drop info was outstanding. Before this vid I had little interest in war army tanks with huge death cocks, and I still feel that way, but this vid caused me to come away satisfied, educated, informed.

We in the West aren't worried - shit, you can't even spell it correctly........

Is there a Stalker edition for these?

"Flat-shooting" rounds (whether from a tank gun or a rifle) are not immune to the effects of gravity. Gravity works on all projectiles as soon as they exit the bore (and are no longer supported by the barrel). The apparent "flatness" of the trajectory comes from a projectile's speed. All other considerations being equal, any two projectiles flying through the air both drop at the same rate - gravity effects all objects equally. So let's imagine the comparison of two projectiles, one traveling at 10,000 fps and the other at 2,000 fps. (We'll ignore velocity loss due to drag to make this simple.) If they are both fired at a target 10,000 ft away, the first round gets there in one second, while the latter round gets there in five seconds. That means that gravity acts on the first round for only one second, but acts on the second round for five seconds. If both are fired from level barrels (that is, no hold-over for range) the first projectile falls approx. 16 ft from line-of-sight while the second falls a whopping 402 ft! So the hold-over (to put it precisely on target) for the first projectile is minor, while the hold-over for the second is considerable. (This also greatly increases the flight time of the second projectile because it has to travel a much longer, arcing path. The first projectile must also arc - no projectile actually "shoots flat" - but the increase in distance traveled, and therefore flight time, is minimal. This creates the impression the former "shoots flat" while the latter needs a large hold-over because it does not "shoot flat.") The faster the projectile, the less flight time to target. The less flight time to a target, the less time gravity exerts its pull on the projectile, and therefore the less it will drop before it hits its target. Also note that after one second of flight time, both of these projectiles (ignoring other effects as if fired in a vacuum) if fired from level barrels will fall exactly the same distance from line-of-sight after one second (and will both eventually hit the ground at the same time if fired from barrels the same height above level ground). To put it another way, any two similar projectiles (again ignoring effects other than gravity), when fired from a level barrel, will both begin to fall as soon as they leave their barrels, and will both fall at the same rate regardless of their velocities. If the two projectiles postulated above both hit the ground after one second of flight (i.e., they hit the ground at the same time), the first does so 10,000 ft from where it was launched and the second lands 2,000 ft from its launch site. (If you have a barrel that's level to the ground, you can get a very close approximation of how long any projectile fired from that barrel - at any velocity - will remain in flight if fired over flat terrain. Take a bullet or nut or hammer - something dense that won't be affected by air resistance - hold it at the height of the barrel's muzzle, and drop it. The time the object spends falling is the same amount of time it will take gravity to act on the projectile coming out of the barrel. All other things being equal, two objects dropped from the same height will both hit the ground at the same time because gravity acts equally upon all objects over time.) Bullets, artillery rounds, and rocks are ballistic projectiles. They are not flying objects, they are falling objects, and they are all subject to the same forces when they are launched through the air and in a gravity well.

Nice job. Very informative and well spoken!

The big advantage depleted uranium shells have over anti-tank rocket systems, is it is pretty much impossible to intercept and fully stop a DU dart as it is such a highly concentrated mass moving at ridiculous speeds. Basic physics are at play here. It needs an equal force to stop it, and active protective systems relying on explosive shrapnel shells/rockets simply don't provide enough kinetic energy to stop the DU dart. The same idea is why Pk 1 & 2 Patriot missile defense systems suck at intercepting higher density (than air craft) ballistic missiles, as the the anti-air shrapnel missiles struggle against the higher density of missiles vs aircraft. Future Patriot systems moved on to direct intercepting missiles to fix this. Contrast that to man portable anti-tank rockets. Their slower, fatter explosive warheads are more vulnerable to active protective systems that rely on shrapnel explosive devices. Not to mention their electronics are vulnerable to electronic warfare systems.

@@Dimetropteryx I said fully stop. Yes, in theory they can still interrupt the dart, and significantly alter the angle/effectiveness, but it still is going to hit and hit hard. But that is besides my main paint. In comparison to anti tank rockets, DU darts are astronomically harder to stop with an active protective system. Anti tank rockets are fatter, slower (often sub sonic or low super sonic), have a large heat signature, and are full of delicate electronics. DU darts are smaller, denser, MOVE AT ALMOST HYPER SONIC SPEEDS, and have no electronic or mechanical components to be damaged or misdirected or tricked.

Might hit and will hit less hard. And since it relies on its own structural integrity to do its job, anything that compromises that will affect its performance significantly. That it's harder to do is not really interesting or relevant, especially since there are already claims of functioning systems and it's just a matter of continuing to develop a concept that by now could be considered proven. Designers are already close, there is no reason to assume that success isn't imminent.

You can't entirely stop a APFSDS, but reduce its effectivness drastically. Launcher based systems like Iron Fist detonate their interceptor in a distance of 50-80 cm from the APFSDS, with the goal to tilt it. A tilt of only 10° reduces armor penetration about 50%. But since it's really hard for a launcher based systems to be that fast and accurate, they are generally not very effective against KE. Distributed systems like Rheinmetall ADS don't aim to only tilt the rod, but to shatter and break it. That's more effective. The reaction time is not a problem either.

Agreed. Try guiding an anti-tank missile at a target moving between tall buildings or big trees, the missile loses it's window of opportunity very quickly, but a 120mm gun will reach it quickly and pass through a building or a tree if necessary, what would cause a missile to explode prematurely. Also, in the case of wire guided missiles, which are limited to the speed at which the wire can unspool and have very little chance at winning a war in the woods of Europe or the Jungles of Asia...cuz the trees would get in the way & mess up the wires.

The idea of the sabot is to allow a larger surface area for the expanding gas of the propellant detonation to act upon. To obtain the same amount of imparted energy solely onto the much smaller surface area of the bottom of the dart itself would require a MUCH larger barrel pressure in a barrel the same calibre as the dart. The pressure required would be so great as to deform or blow the barrel itself apart.

Fun fact all APDSFS sabot rounds more, or less lose 40-100 m/s of velocity for each kilometer traveled For previous AP shells such as APCBC, APCR....and etc, they would lose more velocity. Idk the exact figures, but perhaps a few hundred meter/sec per kilometer travelled
