The Indian Air Force successfully conducted the drop trial of the indigenous Khagantak-243 Long-Range Glide Bomb (LRGB) on 2 September 2026, validating a new long-range air-to-ground precision strike capability. The 300 kg-class stand-off weapon was jointly developed by Bharat Electronics Ltd (BEL) and Nagpur-based JSR Dynamics Private Limited. Unlike a conventional bomb that falls vertically, this unpowered glide bomb uses wings to glide more than 140 km to its target, allowing fighter aircraft to strike without flying over enemy air defences.
What Is a Glide Bomb and How Does It Work?
A glide bomb is a stand-off weapon, which means it can be released at a distance from the target rather than directly above it. It is also called a Precision Guided Munition (PGM), a weapon that can steer itself to hit a specific point with high accuracy. Unlike a cruise missile, which has an engine to keep it flying, a glide bomb has no propulsion at all.
After release from an aircraft, deployable wings and tail control surfaces give the weapon lift. It uses the speed and altitude of the launch aircraft to glide along a flat, extended path towards the target. A typical release from around 12,000 metres at Mach 0.8 to 0.85 can extend the range to more than 100 km, while a normal free-fall gravity bomb would drop within a few kilometres.
Guidance is what makes it a smart bomb. A glide bomb steers using a combination of an Inertial Navigation System (INS), which tracks movement using gyroscopes and accelerometers, and satellite navigation (GNSS), which includes systems like GPS, GLONASS, Galileo and India’s NavIC, to correct its path in flight. Some variants add a terminal seeker, such as an electro-optical or infrared seeker or a passive homing head, to lock onto the target in the final phase and improve accuracy. Because it has no engine and a small radar cross section, it is harder to detect and cheaper than a powered missile, and it allows the pilot to turn away immediately after release.
The term glide bombing should not be confused with a glide bomb. Glide bombing is a World War II era technique of shallow-angle dive bombing, while a glide bomb is the weapon itself. Early examples like the German Fritz X and Henschel Hs 293 in World War II pioneered radio-command guidance, and modern systems like the American Joint Direct Attack Munition Extended Range (JDAM-ER) and the Israeli SPICE family have made satellite and electro-optical guidance standard.
Khagantak-243 Drop Trial: What Exactly Happened?
The Indian Air Force announced on 2 September 2026 on its official handle on X that it had successfully conducted the drop of the indigenously designed and developed Long Range Glide Bomb (Khagantak-243). The post shared two images, a bomb in mid-glide and the impact, and stated that trials met all objectives, describing it as a significant milestone achieved through Atmanirbhar Bharat and Make in India. The announcement did not mention the launch aircraft, the test location or the range achieved.
Reports from industry and defence sources have filled in the technical backdrop. The weapon is a 300 kg-class airborne Long Range Stand-Off Precision Guided Glide Bomb, the lightest operational member of the Khagantak family. The IAF had awarded a limited series production contract to Bharat Electronics Ltd in February 2025 for an undisclosed number of units and contract value, with the Su-30MKI designated as the first integration platform. Integration with MiG-29K and Mirage 2000 is planned for the next phase. Reports that the 2 September trial was flown from a Su-30MKI at Pokhran are plausible given this plan, but they remain inferences from earlier programme disclosures, not from the IAF statement itself.
The trial validates the weapon’s aerodynamic glide and guidance performance in a real drop, moving the programme from design and ground testing towards user trials and eventual induction. The weapon is not yet in series production.
Key Features and Specifications of Khagantak-243
The Khagantak name draws from the bird’s sharp strike, and the number 243 denotes a family designation, not the total weight. The system is built as a slender cylindrical body with swivel-type mid-body glide wings that deploy after release and five aft control surfaces for stability and steering. It is completely unpowered.

Who Developed Khagantak-243: Bharat Electronics and JSR Dynamics
Khagantak-243 is unusual in India’s precision weapons landscape because it was not developed by the Defence Research and Development Organisation (DRDO). It was designed by JSR Dynamics Private Limited, a private start-up based in Nagpur, Maharashtra, in partnership with the public sector enterprise Bharat Electronics Ltd (BEL) under a Development-cum-Production Partner model.
Bharat Electronics Ltd (BEL) is a Navratna Central Public Sector Enterprise under the Ministry of Defence. It was established in 1954 and is headquartered in Bengaluru, Karnataka. BEL was created to meet the specialised electronic needs of the armed forces and today develops radars, missile systems, electronic warfare suites, naval systems, communications and avionics. For Khagantak, BEL supplies the electronics and guidance subsystems, including the navigation and seeker electronics.
JSR Dynamics was founded and is led by Air Marshal Shirish Baban Deo (Retd), a former Vice Chief of Air Staff, who began aerodynamic work on the concept in a private laboratory around 2013. The company specialises in airborne guided weapons, including glide weapons and lightweight cruise missiles. It is responsible for the weapon body and control systems, including the airframe, wings and actuators. An initial support of Rs 10 lakh from DRDO to the founder’s early laboratory is recorded, but design authority rests with JSR Dynamics.
The partnership was formalised through a Memorandum of Understanding signed at Aero India 2019 in Bengaluru on 20 February 2019 between BEL and JSR Dynamics. At that show the team unveiled three concepts named Waghnak, Khagantak and Vel, described as low cost penetration weapons for domestic and export markets. The Khagantak was later displayed at DefExpo 2020 and at the Maharashtra MSME Defence Expo. The model was to combine the agility of a start-up with the production and certification strength of a defence public sector unit, aligning with Start-up India, Atmanirbhar Bharat and Make in India.
Under the work share, JSR Dynamics builds the aerodynamic shell and control actuation, while BEL integrates the guidance kit, satellite and inertial navigation unit and mission electronics. The prototype was shown with near total indigenous subsystems, a deliberate attempt to reduce dependence on imported kits such as the Israeli SPICE and French Hammer (Highly Agile Modular Munition Extended Range) that the IAF has relied on for precision strikes.
Range, Guidance and Accuracy: How Khagantak-243 Finds Its Target
The key questions about any glide bomb are how far it can glide, how it stays on course, and how accurately it can hit.
How far can it travel? Range is not fixed. It depends on release altitude, release speed, and glide ratio, which is the distance covered horizontally for each metre of altitude lost. Khagantak-243 has a glide ratio of more than 12, so from 12 km it can theoretically cover well over 120 km even before accounting for the boost from the aircraft’s forward speed. The manufacturer’s figure is more than 120 km from 12,000 metres at Mach 0.85. Reports citing more than 140 km and 144 to 180 km describe optimal high altitude, high speed releases. The IAF itself disclosed no range figure for the 2 September trial, and the frequently repeated 180 km number is understood to have originated with the lighter K-225-LW variant in earlier 2020 reporting.
How is it guided? Mid-course guidance combines Inertial Navigation System (INS) and multi-constellation satellite navigation, which keeps the bomb on a pre-programmed flight path and corrects for wind and drift. The system is described as jam resistant, meaning it can continue to navigate even when satellite signals are degraded by electronic countermeasures. For the final approach, the weapon can use an electro-optical seeker, an infrared seeker or a passive homing head. The seeker compares the live image with stored data to refine the aim point.
How accurate and how fast is it? Without a terminal seeker, the manufacturer cites accuracy within 10 metres for 95 percent of drops, and with a seeker, within 5 metres. These figures are expressed as Circular Error Probable (CEP), the radius within which half of the weapons are expected to fall, a standard measure of precision. The bomb itself has no engine, so it glides at subsonic speed, bleeding energy gradually while steering. The launch speed of about Mach 0.8 to 0.85, roughly 980 to 1,040 km per hour at altitude, gives it the initial energy to sustain the long glide.
Can glide bombs be intercepted? Traditional surface-to-air missiles find them difficult to engage. Their tiny radar cross section, lack of a hot exhaust plume, and short, low altitude flight after release make detection late and engagement time short. The most effective countermeasure is to engage the launch aircraft before it reaches the release point, which is why stand-off range is so valuable.
How Does Khagantak-243 Compare With Gaurav and Other Glide Bombs?
India now has more than one indigenous glide weapon, and each fills a different niche.
Gaurav, the DRDO counterpart, is a 1,000 kg class Long-Range Glide Bomb designed and developed by Research Centre Imarat (RCI) in Hyderabad, together with the Armament Research and Development Establishment (ARDE) and the Integrated Test Range (ITR) at Chandipur. It uses a hybrid INS plus GPS navigation scheme with digital controls. Release trials were conducted by DRDO between 8 and 10 April 2025 from a Su-30MKI, demonstrating a range close to 100 km with pinpoint accuracy, as confirmed by the Press Information Bureau release 2120989. Development-cum-production partners for Gaurav are Adani Defence Systems and Technologies, Bharat Forge and several MSMEs, and certification was supported by the Centre for Military Airworthiness and Certification (CEMILAC) and the Directorate General of Aeronautical Quality Assurance (DGAQA).
Other indigenous programmes include TARA (Tactical Advanced Range Augmentation), a modular glide kit that converts existing unguided bombs into precision weapons, which had a maiden flight trial on 7 May 2026 from a Jaguar off the Odisha coast, and SAAW (Smart Anti-Airfield Weapon), a light precision weapon designed to strike runways, bunkers, shelters and command centres from stand-off distance.
Seen together, the lighter Khagantak offers longer reach per kilogram of weapon mass due to its slender high lift glider design, while the heavier Gaurav delivers a far larger warhead.
| Feature | Khagantak-243 | Gaurav (DRDO LRGB) | SPICE 2000 (Reference, Imported) |
|---|---|---|---|
| Developer | JSR Dynamics plus BEL, Nagpur and Bengaluru | RCI plus ARDE plus ITR, Hyderabad and Chandipur | Rafael Advanced Defense Systems, Israel |
| Class | 300 kg, Mk-81 warhead about 125 kg | 1,000 kg class | 910 kg total, warhead 429 kg on Mk-84 |
| Range demonstrated | More than 120 km as per maker, reports of more than 140 km | Close to 100 km in April 2025 trials, design range 30 to 150 km | 60 km stand-off range |
| Guidance | INS plus multi-GNSS, optional electro-optical or passive homing seeker, CEP under 10 m, under 5 m with seeker | INS plus GPS hybrid navigation with digital control, pinpoint accuracy | CCD or IR plus GPS or INS plus DSMAC, CEP about 3 m |
| Propulsion | None, pure glider | None, pure glider | None, pure glider with 12 control surfaces |
| Platform | Su-30MKI first, planned MiG-29K, Mirage 2000 | Su-30MKI | Mirage 2000, F-16, F-15, Su-30MKI in Indian service |
Glide Bomb vs Cruise Missile vs Gravity Bomb
| Aspect | Gravity Bomb (Unguided) | Glide Bomb | Cruise Missile |
|---|---|---|---|
| Propulsion | None, falls ballistically | None, glides on wings | Has engine, sustained powered flight |
| Range | Few kilometres, aircraft must overfly target | Tens to more than 150 km depending on altitude and speed | Hundreds of kilometres, for example BrahMos about 290 km at Mach 2.8, SCALP comparable |
| Guidance | None, accuracy depends on aim and ballistics | INS plus GNSS and often terminal seeker, high precision | INS plus GPS plus active radar or seeker, high precision |
| Cost | Very low | Low to moderate, a JDAM kit costs about $25,000 to $50,000 on a basic bomb | High, a Tomahawk class cruise missile costs about $1.5 to $2 million per unit |
| Role | Area bombing where accuracy is less critical | Stand-off precision strike on fixed or relocatable targets while keeping aircraft outside air defence | Deep strike on heavily defended or distant targets, can manoeuvre for long duration |
| Interceptability | Not guided, but aircraft is exposed during drop | Hard to intercept due to small radar signature and short flight | Easier to detect due to engine heat, but can evade with low level flight |
In short, a glide bomb sits between a cheap gravity bomb and an expensive cruise missile. It gives near missile like accuracy and stand-off distance at a fraction of the cost, which makes it suitable for mass production and saturation attacks against airfields, hardened shelters and logistics hubs.
Why Khagantak-243 Matters for India and What Comes Next
The significance goes beyond a single trial. For years the Indian Air Force has depended on imported precision kits. During Operation Sindoor on 7 May 2025, strikes on targets in Pakistan and Pakistan administered Kashmir were carried out with imported SCALP cruise missiles, Safran Hammer munitions and Rafael SPICE 2000 bombs. Every one of those weapons was bought abroad, which creates cost, supply and strategic vulnerability. A successful indigenous glide bomb directly addresses that gap.
Three benefits stand out. First, stand-off survivability. With a range exceeding 140 km, a fighter can release Khagantak-243 well outside the envelope of short and medium range air defence systems, then turn away. Second, cost and scale. Because it is unpowered and uses largely indigenous subsystems, it can be produced at far lower unit cost than a cruise missile, allowing large stockpiles for sustained campaigns. Third, industry model. The BEL plus JSR Dynamics partnership shows a public-private development-cum-production route that is different from the traditional DRDO to defence public sector unit chain, giving a template for faster iteration through a private design house.
For the IAF, the immediate next steps are clear. User trials must validate performance across different altitudes, speeds and warhead configurations, followed by platform integration tests on Su-30MKI, which forms the backbone of the fighter fleet, and later on MiG-29K and Mirage 2000. The limited series order placed in February 2025 will move to bulk induction only after those trials are complete. In parallel, the broader glide weapon ecosystem will mature, with Gaurav for heavier payloads, TARA as a glide kit for existing bomb stockpiles, and SAAW for airfield denial.
Two caveats merit attention. The IAF has not disclosed an official range for the 2 September trial, so figures of 180 km or more than 140 km should be read as manufacturer and media estimates tied to specific release conditions. Similarly, projections of more than 1,000 units or a sharp drop in import dependence from more than 70 percent to under 20 percent have not been confirmed by an official contract disclosure. BEL is simultaneously expanding a joint venture with Safran to produce Hammer in India, indicating that indigenous development and licensed production are proceeding on parallel tracks.
If trials continue to meet objectives, Khagantak-243 could become a workhorse precision weapon for stand-off strikes, strengthening operational flexibility while supporting the goals of self-reliance in defence manufacturing.
