Banal reason: How depleted uranium shells appeared

After London's declarations of intent, together with tanks to transfer depleted uranium shells to Kyiv, these munitions have become the main topic of discussion in the expert community.

Armor-piercing feathered sub-caliber projectiles, the flight part of which is made of depleted uranium, have an increased penetrating ability due to the density of the material. However, the technology itself is far from new.



The thing is that until the beginning of the 70s of the last century, similar ammunition was used in the United States, but with a tungsten flight part. The density of this metal is 19,25 g per cubic centimeter, which is almost twice that of steel and 63% that of lead.

Meanwhile, by the end of the 70s, tungsten shells began to be replaced by depleted uranium ammunition. The reason is banal - after the dollar was decoupled from the gold standard and the oil ultimatum from Saudi Arabia, tungsten prices soared almost 4 times.

At the same time, depleted uranium, which has a density of 19,05 g per cubic centimeter, was in abundance in the United States and cost a penny, as it was a waste in the uranium enrichment process.

Tellingly, despite the density inferior to tungsten, depleted uranium rods showed very impressive results in tests.

In addition, the developers of the ammunition discovered two nuances that made this material even more preferable.

First, the uranium rod, unlike the tungsten rod, does not collapse when it hits the target, which allows it to penetrate thicker armor.

Secondly, at speeds above 1300 m/s, the uranium flight part of the projectile spontaneously ignites (pyrophoricity) upon contact with armor, which provides an additional damaging effect.

In fairness, it should be noted that the tungsten rod also has this property. But in this case, it manifests itself at a speed of 2800 m/s.

      Just from depleted uranium. Projectile Lead-1 aka 3BM48 winked
      The length of the active part of the projectile is 63,5 centimeters. The core is made of an alloy based on depleted uranium and has a high elongation, which increases its penetration, and also reduces the impact of dynamic protection, since the longer the projectile, the less of it interacts with passive and active barriers at a certain point in time. Sub-caliber stabilizers have been introduced, which improves the accuracy of the projectile, and a new composite leading device with two contact zones is also used. OBPS "Lead" was the most powerful Soviet projectile for 125-mm tank guns. The average armor penetration on a homogeneous steel plate from 2 km along the normal is 600 mm.

    How about screens. You can put double, triple.

      Weight and again weight, a lot is possible, but everything rests on the chassis (weight) in the absence of a reliable engine in the range from 1000 to 2700 sq. Therefore, we do not have uranium screens like theirs. They could not even put a 1200 square armature on the assembly line.

      Armor, like screens, cannot be increased indefinitely. Strengthening of protection goes along the line of dynamic and active protection. True, such defenses have a drawback - they cannot withstand intense shelling (protection charges run out), and secondly, they are dangerous for their infantry if they are next to the tank - for this reason Israel and NATO countries do not use them. Although there is already non-explosive dynamic protection, which is just not dangerous. Plus, active protection electronics can be disabled by shelling from machine guns or small-caliber guns

    Interesting - did you try to make bullets from a depleted tap?
    Ballistic coefficient should be good

      Depleted uranium bullets are too expensive. There cannot be many of them in the ammunition load. And in the heat of battle, they may not pay attention, and release valuable uranium bullets instead of ordinary ones. But for large-caliber sniper rifles, from which especially valuable objects are hit, this is a very good idea. plus

    Something in the slide of the Ministry of Defense of the Russian Federation dedicated to the supply of shells with depleted uranium - the density of the tungsten core is indicated 17,1-17,3 g / cm3, but uranium is just the opposite more dense 18,2-18,4 g / cm3

    Who to believe boom? drinks

      The reason for the appearance of shells from depleted uranium is indeed banal, until 2013 there were deliveries of uranium to the United States, they, in turn, shared it with the UK.

        There were supplies enriched!
        No one will make shells out of it, you can go bankrupt ...

          You can not only go broke because enriched uranium is very expensive, but in addition it is also very radioactive. And also with a mass, if I'm not mistaken, 15 kg, it is prone to a chain reaction.

      Alloys are used, uranium with titanium or magnesium, tungsten is also with something. By itself, tungsten is brittle.

      The core is not pure and brittle tungsten, but tungsten carbide.
      To do this, soot is added to tungsten and something else that lowers the density of this alloy.

    Tantalum also has pyrophoricity, from which the lining of the cumulative warhead in Western anti-tank rifles. And it is much denser than copper.
    But, judging by the video in TG, they also put a Soviet engineering charge with copper in the lancets.

      There is a ready-made shaped charge of the required weight and penetration. What else to put there?

    Information also slipped through on cumulative shells, in which the funnel was made and uranium.

    I can't wait until it's applied. I wish to see a positive result, how interesting it affects the tank and crew. That's cool
