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 bomb was designed by the nodal Laboratory Research Centre Imarat [6] in Hyderabad with the help of 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 fill their requirement of precision guided weapons. [1] [2]
Under the DRDO's Long Range Glide Bomb (LRGB) project, 2 variants have been planned:
The length of both the bombs is 4 meters. The diameter of both the bombs is 0.62 m. Both bombs have onboard inertial navigation system with GPS and NaVIC Satellite Guidance System.
The 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. [7] On 17 August 2018, the IAF and DRDO did a covert successful trial of Gautham and Gaurav at Pokhran firing range, Jaisalmer. [8]
DRDO and IAF successfully tested 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 Spice 2000. The LRGB is a part of a family of newly developed precision guided munitions with a range of 50 km to 150 km in range. [9]
A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without exposing the launching aircraft to anti-aircraft defenses near the target. Glide bombs can accurately deliver warheads in a manner comparable to cruise missiles at a fraction of the cost—sometimes by installing flight control kits on simple unguided bombs—and they are very difficult for surface-to-air missiles to intercept due to their tiny radar signatures and short flight times. The only effective countermeasure in most cases is to shoot down enemy aircraft before they approach within launching range, making glide bombs very potent weapons where wartime exigencies prevent this.
Prithvi is a tactical surface-to-surface short-range ballistic missile (SRBM) developed by Defence Research and Development Organisation (DRDO) of India under the Integrated Guided Missile Development Program (IGMDP). It is deployed by India's Strategic Forces Command.
The Integrated Guided Missile Development Programme (IGMDP) was an Indian Ministry of Defence programme for the research and development of the comprehensive range of missiles. The programme was managed by the Defence Research and Development Organisation (DRDO) and Ordnance Factories Board in partnership with other Indian government political organisations. The project started in 1982–83 under the leadership of Abdul Kalam who oversaw its ending in 2008 after these strategic missiles were successfully developed.
Trishul is a low-level quick-reaction short range surface-to-air missile developed in India by Defence Research and Development Organisation (DRDO) as part of the Integrated Guided Missile Development Programme (IGMDP). It can also be used as an anti-sea skimmer from naval ship against low flying missile, attack helicopter and aircraft.
Astra is an Indian family of all weather beyond-visual-range air-to-air missile, developed by the Defence Research and Development Organisation. Different missiles of this family are capable of engaging targets at varying distances of 500 m (0.31 mi) up to 340 km (210 mi). Astra Mk-1 has been integrated with Indian Air Force's Sukhoi Su-30MKI and will be integrated with Dassault Mirage 2000, HAL Tejas and Mikoyan MiG-29 in the future. Limited series production of Astra Mk-1 missiles began in 2017.
Pinaka is a multiple rocket launcher produced in India and developed by the Defence Research and Development Organisation (DRDO) for the Indian Army. The system has a maximum range of 40 km for Mark-I and 60 km for Mark-I enhanced version, and can fire a salvo of 12 HE rockets in 44 seconds. The system is mounted on a Tatra truck for mobility. Pinaka saw service during the Kargil War, where it was successful in neutralising Pakistani positions on the mountain tops. It has since been inducted into the Indian Army in large numbers.
The "SPICE" is an Israeli-developed, EO/GPS- guidance kit used for converting air-droppable unguided bombs into precision-guided bombs.
Nirbhay is a long range, all-weather, subsonic Cruise Missile designed and developed in India by the Aeronautical Development Establishment (ADE) which is under Defence Research and Development Organisation (DRDO). The missile can be Launched from Multiple Platforms and is capable of carrying conventional and nuclear warheads. It is currently deployed in limited numbers in Line of Actual Control (LAC) during standoff with China.
The Indian Ballistic Missile Defence Programme is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect India from ballistic missile attacks. It was launched in 2000 after Kargil War by the Atal Bihari Vajpayee government. Testing was carried out and continuing as of 2006, and the system was expected to be operational four years from then according to the head of the country's missiles development programme, Vijay Kumar Saraswat.
The Nag missile, also called "Prospina" for the land-attack version, is an Indian third-generation, all-weather, fire-and-forget, lock-on after launch, anti-tank guided missile (ATGM) with an operational range of 500 m to 20 km depending on variant. It has a single-shot hit probability of 90% and a ten-year, maintenance-free shelf life. The Nag has five variants under development: a land version, for a mast-mounted system; the helicopter-launched Nag (HELINA) also known as Dhruvastra; a "man-portable" version (MPATGM); an air-launched version which will replace the current imaging infra-red (IIR) to millimetric-wave (mmW) active radar homing seeker; and the Nag Missile Carrier (NAMICA) "tank buster", which is a modified BMP-2 infantry fighting vehicle (IFV) produced under license in India by Ordnance Factory Medak (OFMK).
A precision-guided munition is a guided munition intended to hit a specific target, to minimize collateral damage and increase lethality against intended targets. During the First Gulf War guided munitions accounted for only 9% of weapons fired, but accounted for 75% of all successful hits. Despite guided weapons generally being used on more difficult targets, they were still 35 times more likely to destroy their targets per weapon dropped.
