The Secret Behind Challenger 3's Testing in Germany

The British Army's armored tanks are about to get a major upgrade. In February 2024, the world got its first glimpse of the Challenger 3 at the International Armored Vehicles conference in London.
This was far from a ceremonial debut. In just four days, the prototype embarked on a critical journey to Germany for a series of grueling trials. Now, in May 2024, live-fire testing is underway, marking a key step towards the Challenger 3's deployment with the British Army.

There are also massive cost implications. DU is essentially a worthless byproduct of Uranium fuel for power stations and A booms, that weapons manufacturers can obtain for zero or low cost. Tungsten is very expensive and china mines 85% of it, 68 thousand tons with Russia a distant second at 3 thousand 600 tons.

The problem with DU rounds is, that these toxic substances stay around after the war is over.

It's an AI generated video with random information about random tank stuff. The whole part of the Depleted Uranium rounds are just bits of non-related articles put together by the AI , to make it seem like a legit article. It would take an essay to debunk each of those bits, but since you ask about the kidneys, that's from an article about US Abrams crews that were hit by friendly fire from other Abrams tanks. Anyway, modern tungsten rounds are actually more powerful than DU rounds, since tungsten penetrators can handle higher speeds before they become brittle, like the DU penetrators.

The new higher pressure gun and higher pressure APFSDS round is hypersonic which is what Challanger 3 is using. 1800 meters a second which is mach 5.24 that’s hypersonic. That’s going to do a lot of damage and be very difficult to stop even with composite and or spaced armour.

[@peterdrought9334]

Thought the whole point of smooth bore guns was greater muzzle velocity for kinetic energy rounds, but at the expense of range. Challenger 2 used rifled guns to enable the use of HESH ammunition , which works in a different way and doesn’t require the same velocity?

[@stunick1573]

It is. Smooth bore beats rifled prove over the years. His comment about the rifled 125mm being better is a lie. Plus American's have the depleted uranium rounds is Britain want's them. This guy is way off with his biased opinions.

[@td6460]

The HESH round works principally not by penetrating armor, but by causing a pressure shock inside the hull, called spalling, which in older generation Soviet armor would essentially turn the affected crew into a smoothie. That is not the case with more modern hull designs which incorporate special lining to prevent those tiny fragments from forming.

[@wacojones8062]

Wait, what? The L/55A1 is compatible with NATO ammo AND US-specific DU ammo also, like the M829A4. So Challenger 3 does not lose access to DU... Germany and other NATO countries haven't bothered with DU ammunition as the L/55 paired with DM63/KE-W A4/DM73 outperforms the latest generation DU rounds. The L27A1 APFSDS is the latest development of DU ammunition for the Challenger 2, it boasts a muzzle velocity of 1,650m/s. DM53 has a muzzle velocity of 1,670m/s, DM63 has a muzzle velocity of 1,720m/s, KE-WA4 has a muzzle velocity of 1670m/s (L/44 cannon, would be higher from L/55) and DM73 has a muzzle velocity of 1,780m/s... So there is absolutely no negative impact at all in any capacity by switching to the smoothbore L/55. I would highly suggest more research before making broad claims like "... by switching to the smoothbore gun, the Challenger 3 loses DU rounds..." [paraphrased]. The benefit of a smooth-bore gun is that the Challenger 3 is not limited in ammunition supplies in a conflict zone as it can borrow from other NATO countries. It also swaps out the old 2-piece ammunition for single-piece ammunition, giving it faster reload times and allowing for easier ammo storage in the vehicle. Maintenance and barrel cleaning/servicing is quicker and easier as the crew does not have to scrub out the rifling in the barrel. Final point... DU provides health risks to crews of tanks hit by DU rounds? What, like death? Seems to be a side effect of shooting a tank with any AP ammunition...

My understanding was C2 used and loved HESH rounds an in asymetic warfare such as iraq these were fantastic and gave the challenger a real edge as DU sabots for peer tank penetration just weren't needed much. HESH rounds work best from a rifled barrel and there isn't a smoothbore equivalent.

[@latscott]

@@jackpowell9276 I do agree High Explosive Squash Head (HESH) the mainstay of British Army Ammunition for decades and a highly effective 2 part ammunition, is the casualty in this switch from rifled to smoothbore not (DU) Depleted Uranium SABOT as it is already a standardized NATO 120mm smoothbore round. I'm not sure about Germany's stance on DU as they're a little bit more Politically Correct not wishing to anger the Green lobby on this type of issue, and therefore have most likely "well I know", decided to develop the Kenictic Tungsten SABOT round. Remember the UK will have to invest in buying a whole new arsenal/stockpile of ammunition costing Millions of Dollars or Euros for the new smoothbore 1 part round and this is why they're carrying out trials in Germany under Rheinmetall bequest regarding the Tungsten round. Just remember Uranium is actually a harder substance than Tungsten in the periodic table. So really this whole story is about what ammunition to buy in bulk nothing more. I also believe that the remaining 100 or so Challenger 2s which are destined to go into deep storage as a safeguard for any future hostility will have the ability to draw on the already substantial stockpile of the perfectly serviceable 120mm rifled round. Once this rifled ammunition is consumed on the battlefield there would be an opportunity to upgrade these Tanks to MK3 standard or an MK4 even, having the option to leapfrog as and when technology evolves thus maximising your options into the future. Similar upgrade programs like the extended life program on the CVRT family and the radical Scimitar MK1 to the later MK2 programs have been successful adaptations. Another example is the venerable 1960s Cold War era FV432 APC/AFV being upgraded and put back into service in Iraq and Afghanistan which proved to be another successful upgrade program turning the AFV chassis into the Bull Dog. This is my educated take on this whole interlinked story... 🤔

Harmonizing the NATO ammo requirements. Its not an upgrade its a compromise of combined warfare.

Germany does not use DU ammunition, thus they went to L55 gun to increase penetration of non-DU rounds. America still retains the L44 gun because it uses DU ammunition. So if UK chooses to do so it can purchase American made M829 series DU rounds.

[@jonny2954]

Nah. Common myth made up by Abrams fanboys. DU was only better in the 80s when tungsten alloys weren't as advanced, and even then only against semi-infinite steel targets. Tungsten alloys perform equal, in some cases even better than DU against modern NERA arrays because of lower ductility. The US tested the L55 designated as M256E1 and found it to perform superior with tungsten and DU alloy penetrators. Problem was the Abrams stabiliser had issues with the heavier barrel and required a complete refit, which was deemed too expensive. In fact the US wanted to get rid of the M256 since the 90s, just look at the XM360E1. Wouldn't make sense to develop a new higher pressure tank gun if the current one is sufficient, huh? TL;DR: Abrams has erection problems with the longer barrel, so they had to stick with the short one. Meanwhile the Germans are ahead not one, but two generations with the L55A1 (L44

[@levilastun829]

I read that a DU APFSDS round has its maximum penetration potential at a velocity of around 1500 to 1600 m/s. While a Tungsten alloy APFSDS round has its maximum potential at more than 1800 m/s. In addition using lower muzzle velocity rounds could have a slightly higher barrel life, in comparison to a higher velocity round.

[@jonny2954]

@@levilastun829 No. DU rounds still increase penetration above 1600 m/s, just not to the degree they scale penetration up to 1600 m/s. A given projectile of the same weight and dimensions traveling at higher velocity will always have more kinetic energy and kinetic energy is directly related to penetration, regardless of material. Also performance at 1600 m/s is hardly an argument for a 1600 m/s muzzle velocity because when the projectile enters an enemy tank at 2000 meters it's actually closer to 1500 m/s (1480 m/s to be exact). Also higher velocity means less time traveled and flatter trajectory, meaning higher accuracy and hit probability. So ye, absolutely no reason to not go for higher velocity. Just Abrooms fanboys making things up to excuse the Army not upgunning the Abrams because expensive.

[@verdebusterAP]

@@jonny2954 You are just a wealth of disinformation The L55 was not adopted as the US found by reworking the propellant of the M829, they could get the same performance without the need for expensive refit Secondly the XM360 was still highly experimental in the 90s and its Electrothermal-chemical (ETC) was not considered mature enough for use but most importantly it needs an autoloader which the Abrams didnt have

[@jonny2954]

@@verdebusterAP No, you just blindly gobbled up the BS the fanboys made up in defense of the Abrams. If the L44 could've matched the L55 with just a new propellant the Germans would've done the same. They're not stupid. It's _their_ gun tube after all. The M829A3 introduction was literally delayed in 2003 following a _too hot_ propellant mix. L44A1 and L55A1 exist because L44 and L55 are at their pressure limit now. Other Abrooms myths: "M256 ackchyually has higher chamber pressure than the L44" No. Same gun tube. Recoil mechanism and mout is different, that's it. "M256/L44 ackchyually have higher chamber pressure than the L55 because it's shorter" Also no. Design requirement of the L55 was literally that it can sustain the same or higher chamber pressure than the L44 for ammunition commonality. "Germans only switched to the L55 because they have to offset performance of non-DU ammunition" This is the funniest one. DU apparently is the only material that has adiabatic shear, however the Americans _themselves_ created self sharpening tungsten alloys at the US Army Research Laboratory in the early 90s. Whoops. DM63 fired from a L55 doesen't just match a M829A3 fired from a L44. It _outperforms_ it. So either the Germans accidentally overshot the target of matching DU ammo, or they actually had a real reason to make sure they can penetrate modern Russian armor (perhaps look at a map and realize most Abrams tanks are in fact on the continent called "America" and most German tanks are less than 1000 km from the Russian border, makes sense eh?) Germans got a gun now that's both higher pressure and longer than the M256 and Abrooms fanboys still think it's only to offset the lack of DU penetrators. No. The Germans just have assessed Russian armor capabilities differently than the US and put more emphasis and per-vehicle funding on their armored corps. It's a little obvious once you see a Bradley parked next to a Puma in joint exercises. Also you are confusing the XM360 with the XM360E1. The XM360E1 was specifically designed for the Abrams. While the XM360 was developed to match the performance of the M256 on a lighter vehicle, the XM360E1 was ment to exceed the performance of the M256 on a heavy vehicle.

So unless we have an incident of friendly fire, why are we worried about the health of a potential enemy aggressor? The argument against DU may be in a Parliamentary Report, but the reasoning doesn’t add up. Therefore, I wonder what the real reason is? It’s not about shortage of DU as apparently: “At the other end of the fuel cycle, when the uranium is taken out of reactors and reprocessed at Sellafield in Cumbria for every kilogram of plutonium produced there are 100 kilograms of spent uranium. There are at least 20,000 tonnes of DU in store at Sellafield alone.12 Jan 2001” Hmmm!?🤔

[@zhufortheimpaler4041]

thats a stupid british myth. To anyone who knows a little bit about tank gunnery, it is very clear that rifled guns are inferior to smoothbores. why? because the rifling makes the gas seal less tight, increases friction and requires a more complex sabot for APFSDS rounds, to neutralise the rifling, as rifling does work against APFSDS rounds not for them. The L30a1 120mm L/55 rifled of challenger 2 has 2km less effective range, 25% lower average penetration capability with comparable ammunition, lower barrel life and requires a more complex sabot than the RH120 L/55a1 smoothbore gun that Challenger 3 now gets.

[@zhufortheimpaler4041]

​@@chrissmith2114 well you are mixing up a few things here ad are stuck in the early 1970s. Nothing to be ashamed of. Yes you are correct that the most muzzle loaded guns were smooth bores (muskets, naval/field guns of the 17th century etc). Rifling was also known at minimum in the 14th century, as we got hunting rifles with rifling of that era. Then around the late 18th early 19th century, european guns got rifling (in the napoleonic wars) and the first breech loading artillery pieces were issued regularly. At the same time conical shaped projectiles were introduced. both benefittet range and accuracy tremendously. so far you are absolutely right. up to the 50´s guns primarily used full bore projectiles like APCBC (Armor Piercing Capped Ballistic Capped) or full bore HE-Frag Ammunition. (with a few exceptions of early APDS - armor piercing discarading sabot subcaliber rounds) The Full Bore AP and HE rounds have a low Length-Diameter Ratio, meaning the Projectile is often just 3-5 times its Diameters long, and are conical shaped. So a 75mm APCBC PzGr.39 for PzKpfW. IV has a projectile diameter(caliber) of 75mm, and a projectile length of 300mm (Lenght/Diameter Ratio is 4:1) These projectiles required the rifling for spin stabilisation. In the later stages of WW2 APDS ammunition started being used by all sides. This is effectively a APCBC projectile with about 40-50% of the size of the regular one for the gun caliber. These were fitted into so called bottom sealed sabots, that carried the projectile through the barrel and discarded after leaving the barrel. These projectile styles (APDS) were used by NATO until about 1978, by the UK until 1985. APDS stilll requires rifling for stabilisation but due to the smaller projectile mass and size, the projectile has greater muzzle velocity and effective range than a full bore projectile. NATO used the L11a5 120mm rifled and L7 105mm rifled guns for this. In 1962 the sovjet union introduced T-62 with a smootbore gun and a novel projectile type. The 115mm U-5TS/2A20 smoothbore gun and the BM-4 APFSDS-T round. APFSDS - Armor Piercing Fin Stabilised Discarding Sabot. This was kind of the biggest revolution in gun and ammunition technology since the introduction of conical projectiles and riflling. APFSDS Ammunition have a high Length-Diameter Ratio. Meaning the projectile is ALOT longer than thick. 15-30 times longer than its thickness in most cases. So you got a long slender dart with fins at the end, like an arrow from a bow. These projectiles retained ALOT more energy on range than APDS and could reliably hit and penetrate targets on about double to triple the range of APDS. As example: L15A4 APDS for the Chieftan or Challenger 1 has an effective range of about 900m vs heavy armored targets (lke a T-72), while a DM23 APFSDS form Leopard 2 has 1800+m effective range vs the same target. (both projectiles were used in the early 80´s) The tricky thing is, that physics is a bitch. While the shorter full bore and sub caliber projectiles that were used untl then really benefitted from the riflinigs spinning to achieve stability and precision, the dart like APFSDS rounds got the opposite effect. When spun by rifling the darts started to rotate around their center of mass. meaning the tip and rear started to wobble outwards, bringing the dart into a hard tumble, wiich basicly neutralised its energy in less than 500m. To counteract this, the L7 105mm guns APFSDS, and the 120mm L11A5/L30A1´s APFSDS rounds have a more complex sabot, that neutralises the rifling. The Rifling does have no positive effect on these projectiles, on the contrary, it has a very detrimental effect. That Challenger 2 gets called a sniper tank is a result of british mystification of their tanks. In fact, even in the 80´s both M1A1 and Leopard 2A4 had vastly greater effective ranges and precision with their 120mm smoothbores than Challenger 1 or later Challenger 2. Leopard 2A6 has close to double the effective range of Challenger 2(close to 6000m) and can hit a 1m² target on that distance with 98% first hit propability. Challenger 2 caps out at around 3500m. Challenger 2 is no sniper tank. And the L30a1 rifled gun is a significantly worse gun than the L/55a1 that Challenger 3 gets now. With DM73 APFSDS the L/55a1 achieves 40-45% higher penetration than the L30a1 with its best ammuninion (L27A1) and can hit and penetrate modern tanks like T-90M´s on up to 6000m, while the L30a1 will struggle with a T-90 on 3200m or even 2000m. its absolutely ok to be not that hardcore into tank guns etc. but please dont spread stupid myths like "rifling is better than smoothbore". There is a reason why no developed nation is using rifled guns anymore. And its not NATO Standardisation.

@@zhufortheimpaler4041 India chose the rifled barrel for their main tank the Arjun, which was chosen because a rifled barrel can fire more types of ammunition than a smoothbore. Tank on tank battles are very rare and take place at quite short ranges. The best way to deal with enemy tanks is ATGM, which is why Bradley was responsible for more tank kills in Iraq wars with its TOW missiles, and even its 25mm chaingun can disable tanks. MBT have been basically made almost obsolete by drone and ATGM, and MBT these days mainly for bragging rights.. And the jury is in any case still out on smooth vs rifled barrel.

Why not test it in a real battle scenario like in Ukraine After all, Britain supplied Ukraine with several Challenger two tanks Russian Kornet missile with tandem charged warheads quickly defeated the tank’s unprotected sections The result was Ukraine withdrew Abrams tanks from the front line action amid Russian barrage of drone attacks which left no ground safe for Tanks ... along with the British Challenger 2 and German-made Leopard 2 tanks The Challenger was not popular with Ukranian Tank Crews, the tank’s 1,200-horsepower engine is under-powered for a 71-ton vehicle. Challenger 2s often get bogged down in Ukraine’s soft soil and needed towing by other Challengers or engineering vehicles. Ukraine never got add-on armor on the sides of the hull and the lower frontal plate left the tanks vulnerable and the extra three tons of weight would make Ukrainian Challenger 2s even less mobile on soft ground The Russias took advantage of the weakness by deploying drones handheld anti-tank weapons, and heavier munitions that blasted right through the unprotected sections Challenger 2s amounted to an error in Ukraine’s order of battle.

Losing D.U. rounds has nothing to do with the switch to a smoothbore gun. That's all health and environment related. Smoothbore are in fact better for firing discarding sabot ammunition, like the current D.U. rounds. The round the Challenger can no longer use is the H.E.S.H or high explosive squash head round. That needs rifling to spin it for stable flight (accuracy). Sabot rounds like D.U. use fins for stabilisation, spin even works against this to some degree. British Army wanted to retain H.E.S.H for Challenger 2. As it's useful against light armour and soft targets behind cover. D.U rounds are only really useful against heavy armour.
