Igen, legalábbis a hírekből ezt lehet kivenni. A szovjet eszközöket ugye elvitték, de a kelet-német hadsereg tulajdonában lévő cuccok ott maradtak. Aztán 1993 után mint a döglegyek a sz@rkupacra, úgy vetődtek rá ezekre a NATO országok szakértői. :)
A tesztről csak copy-paste-elek, ez az 1997/7-es Jane's International Review-ben megjelent cikk:
"IMPENETRABLE RUSSIAN TANK ARMOUR STANDS UP TO EXAMINATION"
By Richard M. Ogorkiewicz
Claims by NATO testers in the 1990s that the armour of Soviet Cold War tanks was “effectively impenetrable” have been supported by comments made following similar tests in the US.
Speaking at a conference on “The Future of Armoured Warfare” in London on the 30th May, IDR's Pentagon correspondent Leland Ness explained that US Army tests involving firing trials on 25 T-72A1 and 12 T-72B1 tanks (each fitted with Kontakt-5 explosive reactive armour [ERA]) had confirmed NATO tests done on other former Soviet tanks left behind in Germany after the end of the Cold War. The tests showed that the ERA and composite Armour of the T-72s was incredibly resilient to 1980s NATO anti-tank weapons.
In contrast to the original, or 'light', type of ERA which is effective only against shaped charge jets, the 'heavy' Kontakt-5 ERA is also effective against the long-rod penetrators of APFSDS tank gun projectiles, anti-tank missiles, and anti-armour rotary cannons. Explosive reactive armour was valued by the Soviet Union and its now-independent component states since the 1970s, and almost every tank in the eastern-European military inventory today has either been manufactured to use ERA or had ERA tiles added to it, including even the T-55 and T-62 tanks built forty to fifty years ago, but still used today by reserve units.
"During the tests we used only the weapons which existed with NATO armies during the last decade of the Cold War to determine how effective such weapons would have been against these examples of modern Soviet tank design. Our results were completely unexpected. When fitted to the T-72A1 and B1 the 'heavy' ERA made them immune to the DU (Depleted Uranium) penetrators of the M829A1 APFSDS (used by the 120 mm guns of the Cold War era US M1 Abrams tanks), which are among the most formidable of current tank gun projectiles. We also tested the 30mm GAU-8 Avenger (the gun of the A-10 Thunderbolt II Strike Plane), the 30mm M320 (the gun of the AH-64 Apache Attack Helicopter) and a range of standard NATO Anti Tank Guided Missiles – all with the same result of no penetration or effective destruction of the test vehicles. The combined protection of the standard armour and the ERA gives the Tanks a level of protection equal to our own. The myth of Soviet inferiority in this sector of arms production that has been perpetuated by the failure of downgraded T-72 export tanks in the Gulf Wars has, finally, been laid to rest. The results of these tests show that if a NATO/Warsaw Pact confrontation had erupted in Europe, the Soviets would have had parity (or perhaps even superiority) in armour” – U.S. Army Spokesperson at the show.
On October 20, 1999 extensive trials of T-80U and T-90 protection from various types of threats were conducted at TsNIIO 643a Testing Grounds. The tests involved firing large amounts of ordnance (including several versions of RPG ATGL, light and heavy ATGMs, and APFSDS rounds) at frontal projections of T-80U and T-90 MBTs both protected with Kontakt-V ERA and stripped of it.
T-80U and T-90 MBTs were represented by 3 vehicles each, one with Kontakt-V ERA, one with removed explosive packages and one reserve vehicle. For the ERA part of trials, knocked-out ERA packages were replaced after each shot.
One more T-80U MBT was used for special trials that focused on testing of Shtora-1 EOCMDAS.
The following weapons were used:
* Infantry ATGLs (fired at a distance of 40m)
o RPG-7 (using advanced 105mm grenade PG-7VR with a tandem warhead, pen. 650mm RHA)
o RPG-26 (disposable launcher, pen. >500mm RHA)
o RPG-29 (advanced 105mm launcher, pen. 750mm RHA)
* ATGMs (fired at a distance of 600m)
o Malyutka-2 (pen. >600mm RHA)
o Metis (pen. 460mm RHA)
o Konkurs (pen. 650mm RHA)
o Kornet (pen. >850mm RHA)
* APFSDS (fired from T-80U MBT at a distance of 1,500m, the most likely round is 3BM42)
Each weapon was fired 5 times at each target, for a total of 20 shots per weapon. The total number of shots fired during the trials thus exceeded 150.
The trials yielded the following outcome:
* ATGLs
o T-90: RPG-29 produced a total of 3 penetrations.
No other RPG rounds could penetrate even the stripped target.
o T-80U: RPG-29 penetrated 3 times with ERA, all 5 times without ERA.
Of all other grenades, one PG-7VR penetrated the stripped target.
* ATGMs
o T-90: No ATGMs could penetrate the ERA-equipped target. One Kornet ATGM penetrated the stripped target.
o T-80U: 2 Kornet ATGMs penetrated the ERA-equipped target, all 5 penetrated the stripped target.
No other ATGMs could penetrate.
* APFSDS
o T-90: ERA-equipped target could not be penetrated. Furthermore, after firing the crew entered the vehicle, activated it and was able to execute the firing sequence.
Without ERA, one round penetrated.
o T-80U (data available only for stripped target): One round almost penetrated (3mm hole in the inner lining, no visible equipment damage); two penetrated to 1/2 thickness; one missed the target completely; one hit the gun.
Conclusions (VF)
* RPG-29 proved to be by far the most potent weapon among those used. As powerful as heavy ATGM Kornet, it appeared to assure the frontal penetration of T-80U even for the squad-level firepower. Even though T-90 fared better, it is still not immune to it. Considering sufficient proliferation of this weapon and the fact that this is still a fairly light infantry weapon, it is the most dangerous adversary of modern Russian MBTs, and is a very disturbing development.
* Original reports that ATGM Kornet performance is severely degraded by ERA due to its peculiar order of internal components proved true as the ATGM with at least 100mm higher penetrating potential was not superior to a much lighter RPG-29.
* Report of Shtora-1 EOCMDAS trials is confusing. Being laser-guided, ATGM Kornet should not suffer any interference from Shtora as it only affects IR SACLOS ATGMs. Furthermore, ATGMs can only deviate to the left if the marker is set to the left of both emitters, which is hardly likely. It is possible, however unlikely, that it was caused by a sloppy work of removal the warhead which e.g. could cause a gyro cofusion.
Itt összesen tehát 25db T-72A1 és 12db T-72B1-et említenek, minden volt Kontakt-5 ERA. Érdekesség, hogy a Kontakt-5 a T-72-eseken csak 1989-ben jelent meg, tehát a kelet-németek élből megkapták a legmodernebb upgrade-et.
A lényeg az, hogy sem az Abrams, sem az A-10A, sem az AH-64 nem tudta volna (szemből) átütni a T-72A1 és B1 védelmét a Kontakt-5 ERA-val.
