The Long Range Glide Bomb, also known as Gaurav is a product of the Defence Research and Development Organisation to deploy a standardised medium range precision guided weapon, especially for engagement of targets from outside the range of standard anti-aircraft defenses, thereby increasing aircraft survivability and minimising friendly losses. The development was carried out by Research Centre Imarat with production from Adani Defence & Aerospace and Bharat Forge.[8][9]

Development

[edit]

The bomb was designed by the Research Centre Imarat (RCI)[10] in Hyderabad with the help of the Defence Avionics Research Establishment (DARE) in Bengaluru, Terminal Ballistics Research Laboratory (TBRL) in Chandigarh and Armaments Research and Development Establishment (ARDE) in Pune.[1][2] The team designed the bomb specially for the Indian Air Force to fulfill a requirement for precision guided weapons.[1][2]

The length of the bomb is 4 meters and the diameter is 0.62 m. The wingspan of Gaurav is 3.4 meters. It has a range of up to 100 km and weighs 1,000 kg. It can carry either pre-fragmented or penetration-blast warheads.[1][7] To guide the glide munition towards the target, DRDO Glide Bombs use a hybrid navigation approach that combines satellite guidance and an inertial navigation system with digital control.[11][12] Gaurav is claimed to be able to destroy a wide range of targets, such as reinforced buildings, airfields, bunkers, and blast hardened structures.[12]

Trials

[edit]
  • 19 December 2014: A DRDO-developed 1,000 kg-class glide bomb was successfully tested in the Bay of Bengal. The bomb was dropped from an Indian Air force aircraft and covered a range of 100 km, guided through its on-board navigation system. The flight path is of the glide bomb was monitored by DRDO radars and electro-optic systems situated at Integrated Test Range (ITR), Chandipur, Odisha.[10][13]
  • 29 October 2021: DRDO and IAF successfully tested the Long Range Glide Bomb from a Su-30MKI at Balasore, Odisha. The bomb was released from 10 km altitude and successfully hit a sea based target using laser guidance. It is a 1,000 kg bomb which DRDO developed as an alternative to the Spice 2000. The LRGB is part of a family of newly developed precision guided munitions with a range of 50 km to 150 km in range.[14][15]
  • 14 August 2024: The Gaurav glide bomb was successfully tested from a Su-30MKI, striking a target at Abdul Kalam Island. Using electro-optical tracking equipment and telemetry provided by the Integrated Test Range, a team comprising DRDO, Adani Defence & Aerospace, and Bharat Forge tracked the trajectory and performance.[8][16][9]
  • 8 to 10 April 2025: Release trials of LRGB Gaurav were conducted from a Su-30MKI by DRDO at the Integrated Test Range, where it was claimed to have demonstrated a maximum range of 100 km with "pinpoint accuracy".[17][18] The weapon was integrated to several stations in various warhead configurations for land targets during the trials.[19]
