Development of modern Russian Tanks armor

Modern Russian Tanks armor Development
Russian tanks armor has developed continuously with the advancement of Anti-tank shell. From T-55 to T-90 tank and from T-90 to T-14 Armata, there is a huge difference in the protection values, although penetration value of AP and HEAT round also improved, still their research in metallurgy to have these armor values with little increase in weight is subjectively appreciable.
In 1957 Research Institute at Kirov Plant assess the armor-piercing resistance of all domestic tanks, both in serial production and prototypes. The assessment of the protection of tanks was carried out on the basis of shelling with a domestic 85-mm projectile. 85mm was choose because in terms of penetration it surpassed 90mm shells of the west. The conclusion was Increasing the thickness of the armor ensures the penetration resistance, but the mass of the tank went above values which were unacceptable. The specialists saw the solution to the problem of reducing the mass of armor in the use of fiberglass and light alloys based on aluminum and titanium as part of the armor, as well as their combination with steel armor. It was also observed that the penetrating effect of the shape charge jet is relatively weak in soils, especially sands. Therefore it was proposed to replace the steel armor with a layer of sand sandwiched between two thin sheets of iron. In 1959 T-55 tanks hull and turret were designed with two-layer armor protection that is steel with aluminum alloy. However, in the process of testing it turned out that the two-layer armor did not have sufficient survivability with repeated hits from armor-piercing-sub caliber shells - the mutual support of the layers was lost. Therefore, further tests were carried out on two combinations of three-layer armor steel aluminum steel and titanium aluminum titanium. By these combinations, the weight decreases slightly but still remained significant. Protection on the T-90 tank is further enhanced with the use of rolled armor improved welding technique. Welded joints of the T-90 turret are made with overlapping in whole. The base of the T-90 turret is made of steel armor of medium hardness, which significantly increases the armor-piercing resistance by 10- 15 percent than turret with cast armor. The armor of T-80U implements the method of so-called "semi-active" protection systems, in which the energy of the weapon itself is used for protection. The main armor consists of cellular cast blocks, filled with polymer, with steel inserts. On the outer surface of the turret's forehead one-piece, V-shaped "Kontakt-5" ERA blocks are installed. The frontal hull armor of T-72 is similar to that of the T-64, even the first series of the tanks used turrets directly converted from the T-64 turrets. Afterward monolithic turrets made of cast armor steel were used. T-72B non-energetic reactive armor NERA, which represents a significant advancement in soviet armor protection. The T-64 tank became the first serial tank in the world with a fundamentally new type of protection, adequate to new means of destruction. Before the appearance of the Object 432 tank, all armored vehicles had monolithic armor. T-90M and T-90MS have improved armor protection over T-90A. Further ERA coverage is also improved. Both use Relikt built-in Explosive Reactive Armor (ERA) in place of the previous Kontakt-5.
