Qrsam

The meaning of «qrsam»

Quick Reaction Surface-to-Air Missile (QRSAM) is a missile developed by the Defence Research and Development Organisation (DRDO), Bharat Electronics Limited and Bharat Dynamics Limited for the Indian Army,[7] meant for protecting moving armoured columns from aerial attacks.[2]

QRSAM has a fully automated Command and Control System. The missile system possesses two four-walled radars both of which encompass a 360-degree coverage, namely, the Active Array Battery Surveillance Radar and the Active Array Battery Multifunction Radar, apart from the launcher while Laser proximity fuze ensures that missile can't be jammed.

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.[3] The acquisition program faced multiple issues, including poor response from vendors and re-tendering to avoid single source acquisition.[8] In the meanwhile, a DRDO project to develop quick-reaction surface-to-air missiles was sanctioned in July 2014 with a budget of ₹476.43 crore (equivalent to ₹613 crore or US$86 million in 2019).[9] The missile was developed in association with Bharat Electronics Limited and Bharat Dynamics Limited with both firms participating in development and manufacturing.[10][11] In 2017, Indian Army's global acquisition program was dropped in favour of the locally developed QRSAM.[citation needed]

Amid tensions with China, existing units of system were deployed on eastern Ladakh border.[12] The operational version meanwhile is awaiting production in mid-2021 after use trials.[1]

This missile is an all-weather, all-terrain surface-to-air missile equipped with electronic counter measures against jamming by aircraft radars. The missile can be mounted on a truck and is stored in a canister. QRSAM uses solid-fuel propellant and has a range of 25–30 km.[7] The single-staged missile utilized by the system is propelled using solid propellants. The missile is equipped with a midcourse inertial navigation system with a two-way data link and a DRDO-developed terminal active seeker. The missile uses optical proximity fuze to increase accuracy and defend itself from jamming.[13] The system has the capability to search and track targets while moving with six missiles that can be fired for six different type of targets.[14]

QRSAM is a compact weapon system and is mobile. It has a fully automated Command and Control System. The missile system comprises two four-walled radars both of which encompass a 360-degree coverage, namely, the Active Array Battery Surveillance Radar and the Active Array Battery Multifunction Radar, apart from the launcher.[14] With a range of 30 km (19 mi) and ability to intercept a target flying high as 10 km (6.2 mi), QRSAM possesses over 90% Indian made subsyetms which will reach 99% incrementally.[1]
