The DRDO Glide Bomb 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 whereas its production-cum-development partner are Adani Defence & Aerospace and Bharat Forge.[7][8]

The DRDO Glide Bomb has the ability to demolish a wide range of targets, such as reinforced buildings, airfields, bunkers, and blast hardened structures.[9]
Development
editThe bomb was designed by the nodal Laboratory Research Centre Imarat[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 their requirement for precision guided weapons.[1][2]
Variants
editUnder the DRDO's Long Range Glide Bomb (LRGB) project, 2 variants have been planned:
- Gaurav - The winged version. 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][6]
- Gautham - The non-winged version. It has a range of 30 km, enhanced to 100 km in the future, and weighs 550 kg. It can also carry either pre-fragmented or penetration-blast warheads.[1] Although this bomb lacks wings, it does include a control surface that works in conjunction with the inbuilt navigation and guidance system.
The length of both bombs is 4 meters and the diameter of both bombs is 0.62 m. The wingspan of Gaurav is 3.4 meters. 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][9]
Trials
editThe DRDO and the Indian Air Force (IAF) successfully tested a 1,000 kg glide bomb on 19 December 2014 that 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.[12] On 17 August 2018, the IAF and DRDO did a covert successful trial of Gautham and Gaurav at Pokhran firing range, Jaisalmer.[13]
Long Range Glide Bomb - Gaurav
edit
DRDO and IAF successfully tested the Long Range Bomb (LRB) on 29 October 2021 from Su-30MKI at Balasore, Odisha. The bomb was released from 10 km altitude which 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]
The Gaurav glide bomb was successfully tested on August 14, 2024, from a Su-30MKI, striking the target at Abdul Kalam Island with precise accuracy. 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.[7][16][8]
