Kanchan armour

 ( Vehicle Armour ) 

The Kanchan armour (literally gold in Hindi) is the name informally given to a modular composite armour developed by India. The armour got its name from Kanchanbagh, Hyderabad, Telangana, where the Defence Metallurgical Research Laboratory (DMRL) is located.

Although the construction details of the armour remain a secret, it has been described as being made by sandwiching composite panels between rolled homogeneous armour (RHA). The number of layers may vary based on the user requirements. This armour is able to defeat armour-piercing discarding sabot (APDS) and high-explosive anti-tank warhead (HEAT) rounds and is known to defeat armour-piercing fin-stabilized discarding sabot (APFSDS).

This armour is lightweight and compact. A new honeycomb structure design of non-explosive and non-energetic reactive armour (NERA) is reportedly being tested on Arjun tanks.

History During development in the 1980s, Kanchan armour defeated a 106 mm recoilless rifle which was tried on the Arjun Tank. During trials in 2000, the armour was able to withstand hits from T-72 tank at point blank range, and defeated all available high-explosive squash head (HESH) and APFSDS rounds, which included Israeli APFSDS rounds.

The Kanchan is also being used on Vijayanta tanks.

Protection Upon impact of a projectile, the armour will — ideally — prevent penetration via compression and decompression methods. As the projectile hits the armour, it faces compression because of the RHA, and then it faces decompression because of the composite. When the projectile passes through several such sandwiched layers, it breaks up those projectiles.

Composition In the 1980s the Kanchan composite had a composition of ceramic, aluminium oxide, fibreglass and some other such materials mixed. The Kanchan composite tried out had two thicknesses, i.e. a plate and a plate. However these two plates had the same weight as a RHA. Hence it is said that Kanchan armour is more volume at same weight. Anti-tank munitions have problems in penetrating such materials.

Kanchan armour composition has undergone massive changes since the 1980s. The volume of the RHA has been reduced to lesser mass because of better metallurgy. The composite has evolved too and it does not use the 1980s technology any more.
