The Defence Research and Development Organisation (DRDO)’s Indigenous Quick Reaction Surface to Air Missile (QRSAM) is scheduled for another round of testing in April 2023, throwing the spotlight back on this home-grown defence technology. Additionally, DRDO is also working on a Medium Range SAM, in partnership with Israel Aerospace Industries (IAI). The first launch of the MRSAM Army Version was carried out successfully in December 2020, and the induction process is currently ongoing.
About QRSAM
The QRSAM is an innovative canister-based system. This unique storage method offers controlled internal conditions, simplifying both transport and storage, whilst lengthening the system’s shelf life. The QRSAM’s exceptional versatility enables it to detect, track, and lock onto targets whilst on the move, or during brief stationary periods.
Range and Mobility
As a short-range surface-to-air missile system, QRSAM’s primary function is to offer a protective barrier to the army’s mobile armoured divisions, shielding them from aerial attacks. The weapon system’s mobility and manoeuvrability facilitate air defence on the move. Designed to be included in the Army’s artillery, QRSAM boasts a range between 25 to 30 km.
Functionality and Operation
The QRSAM is composed of an automated command and control system, two radars – the Active Array Battery Surveillance Radar and the Active Array Battery Multifunction Radar – and one launcher. Both radars offer 360-degree coverage with the ability to search and track targets while in motion. The compactness of the system and the use of a single-stage solid propelled missile enhances its portability. A standout feature is the mid-course inertial navigation system, equipped with a two-way data link and terminal active seeker developed locally by DRDO.
Relevance and Role in UPSC Civil Services Examination
Understanding the intricacies of systems like QRSAM or MRSAM is crucial for candidates preparing for the UPSC Civil Services Examination. Previous year questions often revolve around such themes. For instance, the 2018 question about ‘Terminal High Altitude Area Defense (THAAD)’, a US anti-missile system akin to QRSAM, or the 2014 query related to India’s Agni-IV Missile, a surface-to-surface missile.
Such instances highlight the importance of keeping abreast with advancements and updates related to indigenous defence technologies, their functionalities, and their strategic importance. An understanding of these topics not only aids in tackling objective questions but also provides valuable insights for analytical and application-based questions.
