About:

The QRSAM, is a canister-based system, which means that it is stored and operated from specially designed compartments. 

In the canister, the inside environment is controlled, thus along with making its transport and storage easier, the shelf life of weapons also improves significantly.

Key Features

• The QRSAM is a short range surface-to-air missile (SAM) system, primarily designed and developed by DRDO to provide a protective shield to moving armoured columns of the Army from enemy aerial attacks. 
• The entire weapon system has been configured on a mobile and manoeuvrable platform and is capable of providing air defence on the move. 
• It has been designed for induction into the Army and has a range of 25 to 30 km.
• The QRSAM weapon ensemble, which functions on the move, consists of a fully automated command and control system, two radars — Active Array Battery Surveillance Radar, Active Array Battery Multifunction Radar — and one launcher. 
• Both radars have 360-degree coverage with “search on move” and “track on move” capabilities. The system is compact, uses a single stage solid propelled missile and has a mid-course inertial navigation system with two-way data link and terminal active seeker developed indigenously by DRDO.

Benefits:

• The system is capable of detecting and tracking targets on the move and engaging target with short halts. 
• The system is designed to give air defence coverage against strike columns of Indian Army.
