About Quick Reaction Surface-to-Air Missile (QRSAM)
- Quick Reaction Surface-to-Air Missile (QRSAM) is a missile developed by the Defence Research and Development Organisation (DRDO) in association with Bharat Electronics Limited and Bharat Dynamics Limited for the Indian Army.
 - As a part of a replacement program for its obsolete Osa-AK and Kvadrat missile systems, Indian Army received a go ahead to initiate a global acquisition program for quick-reaction surface-to-air missiles from the Ministry of Defence in September 2007.
 - This missile is an all-weather, all-terrain surface-to-air missile equipped with electronic counter measures against jamming by aircraft radars.
 - QRSAM uses solid-fuel propellant and has a range of 25–30 km.
 
Functioning:
- The QRSAM weapon ensemble consists of a fully automated command and control system.
 - It also consists of two radars – Active Array Battery Surveillance Radar and Active Array Battery Multifunction Radar – with 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.
