Most of the Cold War spaced armour was designed against medium-to-low caliber kinetic munitions, (e.g. 30mm autocannon and 76mm HESH rounds), especially vehicle side skirts. Most of them were made of RHA plates ( Centurion ), or thick reinforced rubbers ( T-72 ), and worked in the same way as did WW2-era ones.
The turret is also provided with a thick steel spaced armour shield over its frontal arc. Over the frontal arc, the vehicle is protected against 30 mm gun rounds at a range of 200 m. [ 38 ] In addition to "hard" protection, the BMP-3's self-sealing fuel tank is located in front of the driver, directly behind the front armour plating.
Sturmgeschütz III with spaced armour plates. Armour with two or more plates spaced a distance apart, called spaced armour, has been in use since the First World War, where it was used on the Schneider CA1 and Saint-Chamond tanks. Spaced armour can be advantageous in several situations.
The turret armour of the T-72B was the thickest and most effective of all Soviet tank armour; it was even thicker than the frontal armour of the T-80B. [58] The T-72B used a new "reflecting-plate armour" ( bronya s otrazhayushchimi listami ), in which the frontal cavity of the cast turret was filled with a laminate of alternating steel and non ...
The Bradley possessed a lightweight aluminum alloy hull, which in most successive marks has been bolstered by the addition of explosive reactive and slat armor, spaced laminate belts, and steel track skirts. [7] Throughout its life cycle, an IFV is expected to gain 30% more weight from armor additions. [14]
An IDF Caterpillar D9 armored bulldozer equipped with slat armor surrounding its driver's cab. Slat armor (or slat armour in British English), also known as bar armor, cage armor, and standoff armor, is a type of vehicle armor designed to protect against high-explosive anti-tank (HEAT) attacks, as used by anti-tank guided missiles (ATGMs) and rocket-propelled grenades (RPGs).
Non-explosive reactive armour (NxRA), also known as non-energetic reactive armor (NERA), is a type of vehicle armor used by modern main battle tanks and heavy infantry fighting vehicles. NERA advantages over explosive reactive armor (ERA) are its inexpensiveness, multi-hit capability, [ 1 ] and ease of integration onto armored vehicles due to ...
This fragmentation by blast wave is known as 'scabbing' or 'spalling', with the fragments termed 'scabs or 'spall'. [4] [2]Depending upon the armour thickness, a heavy piece of target material (4 to 10 kg (8.8 to 22.0 lb) for a 120 mm (4.7 in) round used in Arjun MBT [4]) can separate out from the other end of the target with supersonic velocities.
