This will significantly reduce the penetrating capabilities of the penetrator, since the penetrating force will be dissipated over a larger volume of armour. A KE-penetrator will also be subjected to powerful sideways forces, which might be large enough to cut the rod into two or more pieces. This will force an incoming KE- penetrator or shaped charge jet to cut through more armour than the thickness of the plating itself, since "new" plating is constantly fed into the penetrating body. The plates are arranged in such a way as to move sideways rapidly when the explosive detonates. Introduced on the T-80U tank in 1985, Kontakt- 5 is made up of "bricks" of explosive sandwiched between two metal plates. It is the first type of ERA which is effectively able to defeat modern APFSDS rounds. Kontakt-5 is a Russian type of third-generation explosive reactive armour. Protective measures include Kontakt-5 ERA, laser warning receivers, and the SHTORA infrared ATGM jamming system. The successor to T-72BM, the T-90 uses the gun and 1G46 gunner sights from T-80U, a new engine, and thermal sights. Deliveries are to begin in 2008.ĭerived from the T-72, the GPO Uralvagonzavod T-90 main battle tank is the most modern tank in the Russian Army's arsenal. In November 2006, India ordered a further 300 T-90 tanks, to be licence-built by Heavy Vehicle Factory (HVF), Avadi. In March 2006, Algeria signed a contract for the supply of 180 T-90S tanks from Uralvagonzavod, to be delivered by 2011. In January 2005, it was announced that a further 91 T-90S tanks would be procured for the Russian Army. The tanks are fitted with the Shtora self-protection system and thermal imagers from Thales of France and Peleng of Belarus. The locally-assembled tanks are christened "Bhishma". The first of these was delivered in January 2004. 124 were completed in Russia and the rest are being delivered in "knocked down/semi-knocked down" form for final assembly in India. In February 2001, the Indian Army signed a contract for 310 T-90S tanks. The T-90S is in service with the Russian Army and the Indian Army. It is manufactured by the Uralvagonzavod Plant in Nizhniy Tagil (Potkin's bureau) of the Russian Federation. The T-90S is the latest development in the T-series of Russian tanks and represents an increase in firepower, mobility and protection.
