T-80 con blindaje ERA Relikt

Hace algunos años aparecieron varias modernizaciones del T-80. Una de ellas se puede ver en la foto. Se trata de un T-80B con blindaje ERA Relikt, más moderno que el Kontakt-5. 


Lo más probable es que simplemente fuese un vehículo de pruebas, porque no se aprecían más cambios. Cuando el ejército ruso adquirió versiones modernizadas del T-80, tenían mejoras en otros apartados, como una cámara térmica.

  1. Alejandro,
    que datos tienes tu sobre este ERA? Consigo informaciones exactas sobre el Kontakt-5 pero el Relikt y el Kaktus me resulta dificil.

  3. No hay demasiado en cuanto a cifras exactas de la protección que ofrece Juan Francisco: Kampfpanzer tiene ésto referido al T-90MS

    Protection system
    Besides the fire control system, the improvement of the active and passive protection was one major requirement in the development of the T-90SM. Most visible change is the usage of Relikt ERA. Compared to the previously used Kontakt-5, Relikt offers a significantly higher level of protection against incoming HEAT and kinetic rounds. The new armour consists mainly of 4S23 modules, which are placed on hull and turret front, as well as the turret top. The new armament can be recognized by the much closer coverage of the basic armour. As the T-90SM is not using any IR jammers, the reactive armour is added on the turret until close to the main gun. Another advantage of Relict is the possibility to replace modules easier, as they are not build into the hull front anymore.

    The hull sides are covered over the full length by heavy side skirts. The lower part of the skirts is additionally covered by metal-enforced rubber skirts. These light skirts are flexibly mounted, so they don’t get damaged when driving through rough terrain. Beside increasing the passive protection, the large scale usage of skirts is also reducing the IR signature of the suspension and suppressing the dust clouds. If needed, 4S24 ERA modules can be mounted on top of the side skirts. As they are quite heavy, the modules are not mounted during normal operation.

    The rear sides of the hull are also equipped with slat armour, meant to detonate incoming rounds before they hit the vehicle.
    The turret front is also heavily armoured with the new Relikt modules. The same goes for the area of the turret top in front of the two hatches. Turret sides are not covered with ERA, but storage boxes and add on armour plates. The later ones are similar to the heavy side skirts and simply detonate impacting rounds earlier. The turret rear is again protected by slat armour, which also acts as storage basket.

  4. También esto, del foro defensetalk:

    "Relikt is 5 time better then K-5 against APFSDS. However on real tank ERA - is only the part of whole armor, then the effect of putting Relikt instead K-5 apply will naturally be diminished slightly. With K-5 its effect on the real tank will multiply the capability of a round by coeff 0.81 (APFSDS)-0.5(cummulative), with Relikt - by 0.65 (APFSDS) -0.47 (Cummulative). For example, when M829A2 penetrating capability for steel is 750 mm , it will penetrate only 0.65x750=487mm of T-72 armor with Relikt ERA. Source: NII Stali article http://www.niistali.ru/article/article_04.htm (Russian only, sorry)

    From the same site:

    "At RUSSIAN EXPO ARMS 2006 exhibition held in Nizhniy Tagil on July 11-15 a new multi-purpose ERA package made by NII Stali was demonstrated on an upgraded T-72B tank (“Sling-shot”).


    At RUSSIAN EXPO ARMS 2006 exhibition held in Nizhniy Tagil on July 11-15 a new multi-purpose ERA package made by NII Stali was demonstrated on an upgraded T-72B tank (“Sling-shot”).


    The new ERA package is almost twice as effective as Contact-V ERA system.

    It is called multi-purpose not only because it defeats both HEAT-warhead and KE ammunition, but also because it is made as a number of separate modules, which makes it possible to fit the package to any tank types using standard modules and attachment fittings."

    also:

    "INTEGRATED MODULAR ERA SYSTEM FOR T-72 M1 MBT
    The kit consists of a glacis plate ERA module, quickly removable ERA boxes fitted to the turret roof and sides and on the hull sides; and rubber-fabric screens for the hull sides.

    The kit ensures increase of counter-APFSDS and counter-HEAT protection level of the MBT in the fire angles of ±20° (the hull) and ±35° (the turret).
    Counter-APFSDS protection increases by factors of 1.5-1.6;
    Counter-HEAT protection increases by a factor of 2.0;
    Coverage of the turret and hull surface: 60-68%;
    Weight of the kit: 2,300 kgs.

    The ERA tiles do not detonate when hit by small arms bullets (up to 12.7mm), fragments of 125mm HE rounds or when exposed to incendiary mixtures (napalm).
    The ERA kit can be installed and repaired by the Army field repair groups." http://www.niistali.ru/pr_secure/t72_en.htm "

    1. Muchas gracias Ernesto esta era la informacion que estaba buscando!!
      Gracias a esos datos en teoria un T-72B con Relikt ERA deberia aguantar sobre el arco frontal la mejor municion de flecha disponible para el Rh120/55, aunque eso si, solo por los pelos!!

      Un saludo

  5. Si, por los pelos pero debería. El M891E4 estadounidense que en teoría debería estar empezando su producción está en teoría diseñado para vérselas con el Relikt. A todo ésto, y también en teoría xD lo que lleva el Armata es superior al Relikt...la vieja historia de siempre!
