Dr AQ Khan Research Laboratories AORAK Mk 1 Explosive Reactive Armour
Date Posted: 22-May-2003
Development / Description
The Dr AQ Khan Research Laboratories, well known for the design, development and production of missile and rocket systems, have developed the AORAK Mk 1 explosive reactive armour (ERA) system to improve the combat survivability of tanks and armoured fighting vehicles against attack from Chemical Energy (CE) projectiles.
So far, the Dr AQ Khan Research Laboratories have developed three different sizes of ERA modules to meet different user requirements.
They are known as Type A, B and C and differ only in their size. Each module consists of two thin steel plates between which the explosive is inserted. This in turn is inserted in a box which is then bolted on to the hull or turret of the vehicle.
Efforts have also been made "‹"‹to reduce the risk of accidental detonation of the ERA modules by small arms fire, shell fragments and lightning strikes as well as reducing the sympathetic detonation of surrounding ERA modules.
This armour system is claimed to have a shelf-life of 10 years and an operational temperature range of -40 to +52 º C.

Development complete. Believed to be in low-rate production for the Pakistan Army for installation on Type 59, 69 and 85 series MBTs. Late in 2000, Pakistan showed the Al Khalid and Al Zarra MBTs fitted with ERA over their frontal arc. At this stage, the source of this ERA is not known. Al Khalid is now entering production for Pakistan with 315 to be built over a three year period.
