India’s next generation air defence system:QR-SAM

Canister mounted QRSAM is a highly mobile air defence system which comes with 100 percent kill probability, and has the capability to neutralise aerial targets like fighter jets, cruise missiles and air ­to ­surface missiles as well as short-range ballistic missiles. QRSAM is also a vital component in India’s “Cold Start” Doctrine which will ensure the safety of forward Army formations in Enemy territories.The Mach 1.8 QR-SAM will have a kill-zone of between 3km and 30km in range, from 30 metres to 6km in altitude, and 360-degree in azimuth.

The IAF-specific variant of the QR-SAM will be employed exclusively for cruise missile defence (CMD), in particular against China’s ground-launched CJ-10/DF-10A and air-launched K/AKD-20 land-attack cruise missiles or LACM (all these being clones of the Ukrainian Korshun LACM that had been developed in the Nineties by Dnipropetrovsk-based Yuzhnoye State Design Bureau and Yuzhnoye Machine-Building Production Association, or Yuzhmash), and against the Babur (a DF-10A clone) and Ra’ad LACMs of Pakistan.

For the IA a typical QR-SAM Regiment will comprise a Regimental Command Post Vehicle (RCPV), one S-band 90km-range air-defence tactical control radar (ADTCR) for volumetric airspace surveillance, and three Batteries, each of which will include a Battery Command Post Vehicle (BCPV), a 120km-range C-band active phased-array Battery Surveillance Radar (BSR), and four Combat Groups (CG). Each CG in turn will comprise an X-band 80km-range active phased-array Battery Multi-Function Radar (BMFR), plus a 16km-range optronic fire-control system, and four Missile Launch Vehicles (MLV), each of which will carry six canister-encased missiles.The missile can engage aircraft at 500m/s at 20 km and 300m/s at 30 km.The missile also has terminal guidance using an RF seeker. The system has AESA radar with X-band Quad Transmit Receiver Modules (QTMs), Two Way Data Link (TWDL) and IFF.The BSR and BMFR uses advanced motion compensation & electronic stabilization algorithms to along with high accuracy motion sensors .

Truck based QRSAM Air Defence System can move at speed of 50kmph and has the ability to operate nearly 8 hours at a stretch without the need for refueling. High Mobility Vehicle (HMV) used are capable of being operated in plains, deserts,semi-deserts, terrains found in India and can also be transported through broad gauge rakes of Indian railways.

HMV also has NBC (nuclear, biological, chemical) system installed which ensures reliable protection of the crew and internal equipment against mass destruction weapons. HMV also have a Navigation system and Night vision devices to help Driver and Commander to move in the dark and also in unfamiliar terrains.

As for the CMD network’s projected deployment sites, two little known villages in the Alwar and Pali districts of Rajasthan have been selected for the first two QR-SAM Squadrons. Rajasthan’s State Forests Department has cleared the acquisition of 850 hectares of land in Khoa in Alwar district, and 350 hectares in Roopnagar for installing a CMD grid that will protect the western and southern approaches to India’s National Capital Region. Site selection work for a similar CMD grid meant for Jamnagar and Mumbai is now in progress.
