The Long Range Glide Bomb, also known as Gaurav is a product of the Defence Research and Development Organisation (DRDO) 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.
The development of glide bombs by the DRDO was first reported in June 2013. The guided bombs would carry varying payloads of , and . The agency had already conducted two trials of such bombs. The developmental trials were expected to be completed by 2014-end. The then DRDO chief also announced the development of an anti-radiation missile by the agency, which was later christened Rudram.
The bomb was designed by the Research Centre Imarat (RCI) 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. The team designed the bomb specially for the Indian Air Force to fulfill a requirement for precision guided weapons.
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. 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. Gaurav is claimed to be able to destroy a wide range of targets, such as reinforced buildings, airfields, bunkers, and blast hardened structures.
