20.10.1999 T-80U and T-90 Protection Trials
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)
* RPG-7 (using advanced 105mm grenade PG-7VR with a tandem
warhead, pen. 650mm RHA)
* RPG-26 (disposable launcher, pen. >500mm RHA)
* RPG-29 (advanced 105mm launcher, pen. 750mm RHA)
* ATGMs (fired at a distance of 600m)
* Malyutka-2 (pen. >600mm RHA)
* Metis (pen. 460mm RHA)
* Konkurs (pen. 650mm RHA)
* 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
T-90: RPG-29 produced a total of 3 penetrations. No other RPG
rounds could penetrate even the stripped target.
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
T-90: No ATGMs could penetrate the ERA-equipped target. One Kornet
ATGM penetrated the stripped target.
T-80U: 2 Kornet ATGMs penetrated the ERA-equipped target, all 5
penetrated the stripped target. No other ATGMs could
penetrate.
APFSDS
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.
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
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.
see the big big holes marked in red on the T80 and T90, dun play
play ah russian ATGW is good ah.
