How does NERA armor work?
Non-Explosive Reactive Armor (NERA or NxRA) uses passive material, such as rubber, sandwiched between two metal plates. The loads from NERA inflicted on the vehicle’s structure are much smaller than ERA, and therefore can be applied to lighter vehicles.
What are those blocks on Russian tanks?
Reactive armour is a type of vehicle armour that reacts in some way to the impact of a weapon to reduce the damage done to the vehicle being protected. It is most effective in protecting against shaped charges and specially hardened kinetic energy penetrators.
How strong is Chobham armor?
Depending on the exact penetration, the armor array provides 5.35 to 7.14 times as much protection as a single plate of steel armor of the same weight (for an estimated penetration of 300 to 400 mm steel armor).
What tanks use Chobham Armour?
Only the M1 Abrams, Challenger 1, and Challenger 2 tanks have been disclosed as being thus armoured. The framework holding the ceramics is usually produced in large blocks, giving these tanks, and especially their turrets, a distinctive angled appearance.
How strong is tank armor?
A modern M1A2 is rated equivalent to around 800 millimeters versus tanks shells and 1300 verses shaped charges. By contrast, 90s-era 120 millimeter sabot shells could pierce the equivalent of around 700 RHA, and the AT-17 Kornet anti-tank missile can penetrate 1300 millimeters.
How does reactive armor on a tank work?
A typical explosive reactive armour consists of plastic explosives like C4 sandwiched between two metal plates. These are mounted on the top of the regular tank armour. When the warhead hits the upper plate, it ignites the explosive. The shockwave created by the explosion scatters the molten metal jet away.
Does the M1A2 have reactive armor?
U.S. Army soldiers in Europe are adding extra protection to their M1A2 Abrams main battle tanks in the form of explosive reactive armor.
How thick is the armour plating on a tank?
development of. Until the 1960s, tank armour consisted of homogeneous steel plates or castings. The thickness of this armour varied from 8 mm on early tanks to 250 mm at the front of the German Jagdtiger of 1945.
