    Advantage of ERA in early phases of battle!





    found some footage about the chechen war and at 6:28 you can see a rocket stuck inside the armor of a t72b..

    T-72B hit by SPG9... ERA+hit on a thick point of the turret armor=no penetration.

    vehicle is in good shape despite it is abviously disabled and damaged.


    Lesson Learned: ERA on T-tanks are important ( Must Have ) other wise its up in air, The tank is clearly saved by ERAs and live for another day to fight....

    about ERA:

    testing armor ERAWA-1 and-2 ERAWA:
    (тестирование брони ERAWA-1/2)

    Some examples of test on ERAWA-1:

    explanation of the signs
    (Объяснение знаков)

    CP - capability of protection (Возможность защиты)

    CP=(H-Hw)/H

    H- Guaranteed penetration RHA armour with thick "H"
    Hw - real depth of perforation RHA amrour (witness) after perforation ERAWA brick

    For ERAWA-1 CP is equal to:
    for hit angle 60. CP =~84%
    for hit angle 90. CP= ~67%

    ERAWA-1 was tested against:

    1. Small fire (7,63 12,7 14,5)
    This fire can't detonated ERAWA brick. 7,63mm (B-32) can't perforate ERAWA external wall
    2. 82mm motar spalls
    fragments (shrapnels) form 82mm motar mine can't reduce ERAWA-1 CP
    3. gasoline on fire - time burning 5-10min
    no CP reduction
    4. napalm - 5-10min
    CP reduction only for 5% (CP= ~79-62%)
    5.incendiary bomb of termite (3000C)
    ERAWA set in fire inside brick, no CP for ERAWA after that.
    6. Drop ERAWA brick for 10m hight on concrete or stell flore.
    no CP reduction



    ERAWA-2

    second (in fact third) generation ERAWA armour - very effective against EFP, double SC, more modern HEAT warhead. This armour wasn't
    optimized against APFSDS.

    Test on Pzf-3:


    result:
    [​IMG]


    Against EFP:


    (according to tests in WITU ERAWA-2 placed in 700mm space form hull side can protect against EFP from 200mm diameter, ERAWA-2 placed on turret roof can protected against EFP formed form 50-155mm dimeter )

    One of advantages ERAWA-1/2 are small bricks (cassette) and possibility of placing close together ERA bricsk without risk loosing CP after one casette detonated. For that any flat area (ex Hull) can be cover by ERAWA in 95% In others ERA from other countries ERA bricks need 40-50mm space around the brick so any flat area can be cover in ~60-70%
