Kontakt-5 is a type of second-generation [1] explosive reactive armour (ERA) originating in the Soviet Union. Due to the shortcomings of Kontakt-1, NII Stali developed a new type of reactive armor, Kontakt-5, so that it also affects the penetration characteristics of APFSDS projectiles, unlike Kontakt-1. In addition, Kontakt-5 is not just additional armor, but is clearly integrated into the vehicle hull. The Kontakt-5 modules have a significantly thicker steel upper side. Depending on the module, they contain one or two 4S22 reactive elements. The explosive of a 4S22 element has the TNT equivalent of 330 g. It is sensitive enough to be activated by impacts from armor-piercing projectiles as well as shaped charge warheads. Kontakt-5 produces a stronger defensive detonation than Kontakt-1 and the thicker steel flyer plate thrown at the APFSDS projectile breaks or bends it. The increase in defensive capability led to the development of more advanced APFSDS projectiles.
Kontakt-5 was first observed on a T-80U in 1985. Later, the T-72B, T-84 and T-90 tanks were also equipped with Kontakt-5. In addition, the T-55, T-62 and BMP-3 tank models can also be equipped or upgraded with Kontakt-5. According to the manufacturer, Kontakt-5 is the first type of reactive armor that effectively protects armored vehicles against tandem shaped charges.
Total mass of Kontakt-5 reactive armor: 2.8 - 3.0 t, Protective effect (RHA equivalent): against APFSDS: 200 - 250 mm, against shaped charges (HEAT): 600 mm,
Introduced on the T-80U tank in 1985, Kontakt-5 is made up of "bricks" of explosive sandwiched between two metal plates. The plates are arranged in such a way as to move sideways rapidly when the explosive detonates. This forces an incoming kinetic energy 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. A kinetic energy penetrator is also subject to powerful sideways forces which may cut the rod into two or more pieces. This significantly reduces the penetrating capabilities of the penetrator, since the penetrating force will be dissipated over a larger volume of armour.
Newer KE penetrators like the US M829A3 were "driven by the need to counter KE-effective explosive reactive armor (ERA)". [2]
Relikt was designed by the Russian army in response to the new developments. Relikt is the 3rd generation of Russian ERA, and is claimed to be twice [3] [4] as effective as Kontakt-5. It can be installed on T-72B and T-90 tanks and was adopted in 2006. [5] [6] The Russian Army T-72B3M main battle tank incorporates Relikt. [7] Developed by NII Stali, Relikt uses a completely new composition of explosives to achieve dynamics protection. Unlike Kontakt-1, it works equally reliably against both low-velocity and high-velocity missiles, doubling protection against shaped charges and increasing anti-tank guided missile protection by 50 percent. [8] Relikt defends against tandem warheads and reduces penetration of APFSDS rounds by over 50 percent. [9]
Kontakt-5 armour is employed by Russia, Ukraine, India (T-90S) and Serbia (on M-84AS MBT), among others.
Monolith (which is often confused with the "Malachit" that was used on the Objekt.187) is the latest (4th) generation Russian explosive reactive armor, mounted on Armata project vehicles.
Reactive armour is a type of vehicle armour used in protecting vehicles, especially modern tanks, against shaped charges and hardened kinetic energy penetrators. The most common type is explosive reactive armour (ERA), but variants include self-limiting explosive reactive armour (SLERA), non-energetic reactive armour (NERA), non-explosive reactive armour (NxRA), and electric armour. NERA and NxRA modules can withstand multiple hits, unlike ERA and SLERA.
Composite armour is a type of vehicle armour consisting of layers of different materials such as metals, plastics, ceramics or air. Most composite armours are lighter than their all-metal equivalent, but instead occupy a larger volume for the same resistance to penetration. It is possible to design composite armour stronger, lighter and less voluminous than traditional armour, but the cost is often prohibitively high, restricting its use to especially vulnerable parts of a vehicle. Its primary purpose is to help defeat high-explosive anti-tank (HEAT) projectiles.
The T-72 is a family of Soviet main battle tanks that entered production in 1973. The T-72 was a development based on the T-64 using thought and design of the previous Object 167M. About 25,000 T-72 tanks have been built, and refurbishment has enabled many to remain in service for decades. It has been widely exported and has seen service in 40 countries and in numerous conflicts. The Russian T-90 introduced in 1992 and the Chinese Type 99 are further developments of the T-72. Production and development of various modernized T-72 models continues today.
The T-80 is a main battle tank (MBT) that was designed and manufactured in the former Soviet Union and manufactured in Russia. The T-80 is based on the T-64, while incorporating features from the later T-72 and changing the engine to a gas turbine. When it entered service in 1976, it was the first production tank to be powered solely by turbine.
The T-90 is a third-generation Russian main battle tank developed from, and designed to replace the T-72. It uses a 125 mm 2A46 smoothbore main gun, the 1A45T fire-control system, an upgraded engine, and gunner's thermal sight. Standard protective measures include a blend of steel and composite armour, smoke grenade dischargers, Kontakt-5 explosive reactive armour (ERA) and the Shtora infrared anti-tank guided missile (ATGM) jamming system.
Arena is an active protection system (APS) developed at Russia's Kolomna-based Engineering Design Bureau for the purpose of protecting armoured fighting vehicles from destruction by light anti-tank weapons, anti-tank guided missiles (ATGM), and flyover top attack missiles. It uses a Doppler radar to detect incoming warheads. Upon detection, a defensive rocket is fired that detonates near the inbound threat, destroying it before it hits the vehicle.
Military vehicles are commonly armoured to withstand the impact of shrapnel, bullets, shells, rockets, and missiles, protecting the personnel inside from enemy fire. Such vehicles include armoured fighting vehicles like tanks, aircraft, and ships.
The Black Eagle tank or Object 640 was a presumed prototype main battle tank based upon the T-80U, developed by the KBTM design bureau of Omsktransmash in the late 1990s for the Russian Federation. The Black Eagle was cancelled, with all production and development halted in 2009.
The Rheinmetall Rh-120 is a 120 mm smoothbore tank gun designed and produced in former West Germany by the Rheinmetall Waffe Munition GmbH company. It was developed in response to Soviet advances in armour technology and development of new armoured threats. Production began in 1974, with the first version of the gun, known as the L/44 as it was 44 calibres long, used on the German Leopard 2 tank and soon produced under license for the American M1A1 Abrams and other tanks. The 120-millimetre (4.7 in) gun has a length of 5.28 metres (17.3 ft), and the gun system weighs approximately 3,317 kilograms (7,313 lb).
Drozd is an active protection system (APS) developed in the Soviet Union, designed for increasing tanks' protection against anti-tank missiles and RPGs. It is considered the world's first operational active protection system, created in 1977–78 by the KBP design bureau of A. G. Shipunov as Kompleks 1030M-01. Its chief designer, Vasily Bakalov, was awarded the Lenin Prize for his work on its development.
The D-10 is a Soviet 100 mm tank gun developed in late World War II. It originally equipped the SU-100 tank destroyers and was later selected for the T-55 tank, equipping these as late as 1979. On the T-55 the D-10 continues to be in active service in many countries.
Armour-piercing fin-stabilized discarding sabot (APFSDS), long dart penetrator, or simply dart ammunition is a type of kinetic energy penetrator ammunition used to attack modern vehicle armour. As an armament for main battle tanks, it succeeds armour-piercing discarding sabot (APDS) ammunition, which is still used in small or medium caliber weapon systems.
The M-84AS prototype main battle tank is a modernized version of the M-84 produced by Yugoimport SDPR in Serbia. M-84AS is sometimes referred to as M-84AB1 and M-2001 and is based mostly on imported components.
The T-72 is a Soviet-designed main battle tank that entered production in 1973. It replaced the T-54/55 series as the workhorse of Soviet tank forces. In front-line Russian service, T-72s are being upgraded or augmented by the T-90, itself a modernized version of the T-72B. The T-72 has been exported and produced in many countries.
