>In 2003, the US military acquired four T-84 main battle tanks from Ukraine for testing and evaluation.>They were shocked to discover that the M829A2 120mm DU APFSDS of the M1 Abrams couldn't penetrate the hull armor of the T-84 when its covered with the Kontakt-5 ERA.Why haven't we seen them being used by Ukraine against Russia?https://twitter.com/GarupanH/status/1787832029188706767?t=Bp9nmaTRzLpjVvAd9iaGUg&s=19
>>61580214They have like 5 of them in service. By the time Ukraine even had a chance to start getting it's shit together after 2014 they came to the conclusion it was more cost effective to just modernize T-64's (and even then it was sluggish).
>>61580214No money to build em during peace yearsNo capabilities to build em after 2022Even the good BTR4 that their military procured in larger numbers and that had working production lines went extinct
that's a russian propaganda accountERA only protects against chemical rounds not kinetic ones
>>61580214>Garupan HistoryThank you saar
>>61580635Heavier flying plates can degrade long rods. That's why the A3 (in service since 2003) and A4 (2011) are optimized against ERA+Compound armor rather than "pure RHA value" against steel or compound armor.

>>61580214>They were shocked to discover that the M829A2 120mm DU APFSDS of the M1 Abrams couldn't penetrate the hull armor of the T-84 when its covered with the Kontakt-5 ERA.Literally the exact reason why M829A3 was created. Also, they don't have very many of them and the majority of the ones built were for export. Given that Ukraine also had extensive T-80 and T-64 stockpiles and production capability and the fact that they were poor, they couldn't afford to make this thing any more than a side project. >>61580635Depends on the type, some are specialized against APFSDS and others against HEAT though I would suspect that anti-kinetic ERA is fundamentally less effective. Kontakt-5 can be defeated by modern 120mm APFSDS however.

>>61580635>ERA only protects against chemical rounds not kinetic onesWrong
>>61580214>Couldn't penetrate, russhill accountKek
>>61580780>Literally the exact reason why M829A3 was created.It was the reason A2 was created, A3 was in anticipation of further ERA technology development. The alleged tests had nothing to do with A3 as the development started around 1999 and it already entered service in 2003
>>61582155The Ukrainian T-84 is based of T-80UD which has better armour than the older T-80BV which is what the Russian are refurbishing into T-80BVM.
>>61580780>>61580780Rumors are both M829A2 and DM53 had anti ERA capability, they have nose profiled in such way it doesn't trigger Kontact-5 ERA.Kontact-5 developers themselves disclosed that M829A2 penetrates T-90 from 5000 m range (in the AD materials for new ERA, buy it, it stop M829A2, Kontact-5 doesn't!)
>[military/government/manufacturer] was SHOCKED to discover [thing that was probably known/suspected for years]
>>61584121>design against your expecatations of thing>finally get thing in your hands>test thing>thing is slightly better than your expectation of it>adjust your future designs against a more realistic version of thingTHE WEST HAS FALLEN, BILLIONS MUST TRANSITION
>>61580214doesn't work against dronestanks are obsolete
>>61580214Because unlike russians Ukrainians know how to build a good tank but usualy they lack the budget. So ready those ass cheeks due rasheed and ivan once ukies restart their proper MIC with the help of of Europe your shit geting phased out
>>61584547hey, look!its one of the idiots who fell for the meme!point at him and laugh!
>>61580740only at extremely specific angles and velocitiesvery ineffective at right angles and higher speeds
>>61584040Russian Nomenclature or rather their need to make ten billion variants of a tank is absolute nonsense>b, bv, m, u, um , bvm, bbc, lgtb+, brap the only one I understand is obr. because thats just the year it was refurbed
>>61580214Someone post webm of Abrams turret lifting up and out of its hull from exploding.
>>61585381It's impossible for an Abrams to lollipop
>>61584106>(in the AD materials for new ERA, buy it, it stop M829A2, Kontact-5 doesn't!)Damn that's even more embarrassing than a War Blunder leak
>>61584653>only at extremely specific angles and velocitiesYeah, like most composite armor, all ERA and NERA...
>>61580635>>61580728>>61580807>>61582155What's with all of the mouth breathers here and in the Twitter thread calling him a Russian shill? It's literally a UKRAINIAN tank, and none of what he said is wrong either. It's been known for quite a while that the US bought and extensively tested T-84s. Also, Garupan is Japanese shorthand for "Girls und Panzer". Maybe a weeb isn't much better than a 'jeet, but Christ, /k/ is fucking brain dead sometimes.
>>61585642wrong, NERA is far more polyvalentmeanwhile everything must be just right for flyer plate ERA to be effective against apfsds
>>61586660There's a continuum between ERA and composites (made by plates) with NERA (inert and energetic binder) in between, all of them are angled at angles +70º to be really effective against HEAT or AP.>ERA to be effective against apfsdsAgainst APFSDS NERA behaves like composite armor that relies on variable density to degrade the penetrator, not ideal against long rods when wide-gap spaced armor is far more effective. Physical restrictions and being good enough means that except for turrets those NERA arrays are considered ok, for the hull heavier composites and ERA on top of steel (better than plain RHA) is more common. The binder/refractive lining in between steel plates of NERA don't work at <2 km/s like they do at +4 km/s against HEAT, their RHAeq value is ~0 against AP, all the degradation against APFSDS comes from the variable density of "narrow" gap plates.tl;dr you're wrong, gtfo
>>61586813>refractiverefractory
>>61585900>none of what he said is wrong either.At least you tried. That's what's important.
>>61588835>Weeb tank expert>Stalin>WoTGarbage or excellent parody
>>61584571>once ukies restart their proper MIC with the help of of EuropeI hope this actually happens and maybe Ukes can have their own factories for artillery, aircraft, and tanks
>>61580214The early T-84 used Nizh I believe but if it was that tough. Then Duplet and Nizh-2 is gonna be hard as fuck. Uke tanks are pretty unique for tying to maximize the shitty soviet design into something good. I kind of wish the army would have bough era from Ukraine and use it on out tanks.

>>61580214>Why haven't we seen them being used by Ukraine against Russia?Because Russia doesn't use M829A2 120mm DU APFSDS. They use mostly old Soviet "Mango" rounds that are shit.
>>61585900>russian>ukrainianwhats the difference?
>>61585900Garupan translates to girl undies, actually.
>>61580635Based retard
>>61592720in ERA they're different.Ukrainians ERA bricks have linear shaped charge inside (Nizh ERA), Russians shaped charges are ERA with heavier flying plates (Kontakt-5 and Relikt that can "pre-detonate" to work better iirc)
>>61580214well that's just wrong. m829a3 was in development well before 2003
>>61585189russia and chevy should collaborate to make the most cancerous names for things
>>61580635>shaped charges are now "chemical rounds"
>>61597629It's a valid term.Explosives are chemicals and the action of shaped charges relies on explosives, therefore chemical round.
>>61593211Pan | パン | BreadPantsu | ぱんつ | PantiesGarupan is a shortening of Garu ando Pantsaa, or ガルアンドパンッァー. I had thought that Pantsaa was some sort of play on word of pantsu (panties) given the first thought would be that the correct rendering of the word "panzer" would be パンザ or "panza," but no that is apparently the used transliteration of the word in Japanese.
>>61580214>With the Soviet creation of the Kontakt-5 Explosive Reactive Armor (ERA), the M829A2 was the US immediate response, developed in part to take on this new ERA type. The M829A3 is a further improvement, designed to defeat any future armor protection methods, like 'Kaktus' ERA, which was seen on the now canceled prototype tank, the Object 640 "Chiorny Oriol". It completed type classification standard in March 2003.
