India’s decision to manufacture the HAMMER precision-guided air-to-ground weapon marks a quiet but consequential shift in how New Delhi is preparing for future conflict. More than a new addition to the arsenal, HAMMER represents a move away from importing finished munitions towards absorbing the technologies that define modern air warfare.Developed by France’s Safran Electronics & Defense, HAMMER is a modular precision strike system designed to hit targets from stand-off ranges while keeping aircraft outside heavily defended airspace. Its architecture combines guidance kits, propulsion and standard bomb bodies, allowing rapid adaptation across missions and platforms. The system is already combat-proven and integrated with aircraft such as the Rafale.
Under a new agreement, Bharat Electronics Limited and Safran will jointly manufacture, customise, supply and maintain HAMMER in India through a 50-50 joint venture. The weapon will be integrated across multiple platforms, including the Rafale and the indigenous Tejas light combat aircraft, creating a common precision strike capability across both imported and home-grown fleets.
At a time when air power is defined less by numbers and more by accuracy, stand-off reach and controlled escalation, the localisation of HAMMER signals a strategic shift from buying weapons to mastering precision strike technology itself.
The Indian Air Force deployed HAMMER precision-guided weapons during Operation Sindoor on 7 May 2025 as part of a carefully calibrated cross-border strike against terror infrastructure in Pakistan and Pakistan-occupied Kashmir.Operation Sindoor was launched in retaliation for the Pahalgam terrorist attack that killed 26 civilians on April 22. A total of nine sites were struck, including Jaish-e-Mohammed’s primary base in Bahawalpur and Lashkar-e-Taiba’s hub in Muridke.Weapon selection was central to the operation’s objectives. The Indian Air Force employed a layered mix of SCALP cruise missiles, HAMMER precision-guided bombs and loitering munitions.Within this mix, HAMMER was used where flexibility and adaptability were essential. Its modular design and multiple guidance options allowed the IAF to tailor strikes based on the nature of individual targets and real-time assessments.
HAMMER enabled stand-off engagement without requiring aircraft to fly directly over heavily defended areas. Its off-axis launch capability reduced exposure to Pakistan’s air defence network, particularly in areas close to population centres and sensitive military zones.The weapon’s precision supported the operation’s political and military messaging by reducing the risk of collateral damage. By pairing HAMMER with SCALP, the Indian Air Force demonstrated a layered strike doctrine, with SCALP neutralising deep, hardened targets and HAMMER engaging medium-range sites requiring precision and manoeuvrability.
HAMMER, short for Highly Agile Modular Munition Extended Range, officially designated as AASM from the French Armement Air-Sol Modulaire, is a precision-guided air-to-ground stand-off weapon designed to bridge the gap between conventional bombs and cruise missiles.Despite often being described as a missile, HAMMER is fundamentally a guided bomb system. At its core is a standard unguided bomb, which becomes a high-precision strike weapon once fitted with modular guidance and propulsion kits.
This design allows air forces to convert existing bomb inventories into modern precision weapons without developing entirely new missiles for each mission profile.
The system is built around two main components. The first is a nose-mounted guidance section that determines how the weapon navigates and locks onto its target. Depending on the mission, this guidance kit can combine inertial navigation and GPS for all-weather strikes, infrared imaging for high-precision attacks on fixed targets, or laser guidance for engaging moving targets.The second component is a tail-mounted range extension kit, which includes a solid-fuel rocket booster and manoeuvrable winglets. Once released, the booster ignites to increase stand-off range, while the winglets allow the weapon to alter its flight path, perform sharp turns and attack targets from off-axis angles. In combat, this enables launch aircraft to remain outside heavily defended airspace while still striking accurately.HAMMER kits can be attached to bombs weighing 125 kilograms, 250 kilograms, 500 kilograms and 1,000 kilograms, including widely used Mark 80 series bombs. This scalability allows the same weapon system to be used against a range of targets, from lightly protected structures to hardened bunkers.In operational use, HAMMER has demonstrated the ability to strike targets from significant distances, engage multiple targets in a single sortie and maintain accuracy in contested environments.
Its combination of modularity, manoeuvrability and precision makes it particularly suited to modern air operations where speed, flexibility and controlled escalation are critical.
In modern air warfare, weapons fall broadly into three categories: unguided bombs, guided bombs and air-to-surface missiles.Unguided bombs are cheap but inaccurate and require aircraft to fly directly over targets. Air-to-surface missiles offer long range and precision but are expensive and limited in numbers.
HAMMER sits between these two extremes. It offers missile-like precision and stand-off range while retaining the flexibility and lower cost structure of a guided bomb.This distinction matters. Guided bombs like HAMMER allow air forces to carry larger numbers of precision weapons, adapt them to multiple target types and deploy them from a wide range of aircraft.
The defining feature of HAMMER is modularity. Instead of designing a single fixed weapon, Safran developed a system where guidance, propulsion and bomb body can be mixed and matched.The nose-mounted guidance kit determines how the weapon finds and tracks its target. The rear-mounted range extension kit determines how far it can travel after release and how sharply it can manoeuvre.This modular architecture allows the same basic weapon to be used for close air support, deep strike, bunker busting and attacks on moving targets, depending on the guidance kit selected.For India, this means fewer weapon types to manage logistically while retaining operational flexibility.
HAMMER is available in three primary guidance configurations.The baseline version combines an inertial navigation system and a Global Positioning System receiver. Data from both systems is fused using Kalman filtering, allowing the weapon to maintain accuracy even if GPS signals are degraded or jammed. This variant achieves a circular error probability of around 10 metres and works in all weather conditions.The second variant adds infrared homing to the INS and GPS combination. This system matches the target area with a reference image stored in the weapon’s memory, allowing accuracy of around one metre. It works day and night in fair weather and is particularly useful against fixed targets with a clear thermal signature.
The third variant replaces infrared homing with laser guidance. This allows HAMMER to strike moving targets, provided they are illuminated by a laser designator from an aircraft, drone or ground team.
This version was qualified in April 2013.These variants were redesignated in 2010 as SBU-38, SBU-64 and SBU-54 respectively, with the overall system renamed HAMMER for export.
HAMMER’s range depends on launch altitude and configuration. Safran cites a range of over 32 nautical miles from high altitude and around 8 nautical miles from low-level release.The winglets and rocket booster allow off-axis launches of up to 90 degrees, meaning the aircraft does not have to point directly at the target.
This reduces exposure to enemy air defences.Multiple HAMMER weapons can be released in a single pass against different targets with one trigger press, a capability that significantly enhances strike efficiency.HAMMER entered service in 2007 with the French Air Force and Naval Aviation on the Rafale platform.
Its combat debut came in Afghanistan in April 2008, when a Rafale dropped two HAMMER weapons in support of ground troops.The system gained wider attention during the 2011 Libya campaign. A HAMMER weapon destroyed a Libyan Air Force G-2 Galeb aircraft on the runway at Misrata Airport shortly after it landed. Another strike destroyed a Libyan tank at a distance of 55 kilometres. In total, 225 HAMMER weapons were used in Libya.This combat history is critical. Weapons that have been tested in real conflicts carry credibility in terms of reliability, accuracy and resistance to countermeasures.
India ordered large numbers of HAMMER weapons in September 2020. Deliveries were completed by November 2020, with the French Air and Space Force transferring part of its own stock to ensure immediate availability.The Indian Air Force initially integrated HAMMER on the Rafale fleet. Work has since begun to integrate it onto the Tejas, a process that involves complex software, avionics and flight control modifications.Successful integration on Tejas would represent a major step in combining imported high-end weapons with indigenous platforms.
According to France’s Senate committee on defence manufacturing costs, the total cost of the AASM programme including development and delivery of 2,348 kits was €846 million, placing the per-weapon cost at around $300,000.
Earlier figures showed a unit cost of €164,000 excluding development and €252,000 including development.
By 2017, Safran reported a unit cost of €120,000 for the AASM Evolution version, with a target of reducing it to €80,000 through larger production runs.For India, domestic production offers the potential to lower costs over time while ensuring availability during crises.
India today operates a layered precision strike inventory.Indigenous systems include the Sudarshan Laser Guided Bomb, the Smart Anti-Airfield Weapon, and glide bombs such as Gaurav and Garuthmaa.Imported and jointly developed systems include the SPICE series from Israel, HAMMER from France and the BrahMos-A supersonic cruise missile.HAMMER fills a crucial middle ground between short-range guided bombs and long-range cruise missiles, offering flexibility, precision and affordability.Manufacturing HAMMER in India is not just about supply security. It allows Indian engineers and technicians to gain deep familiarity with guidance systems, propulsion integration and precision strike workflows.
This knowledge is transferable to future indigenous weapons programmes and reduces long-term dependence on foreign suppliers for upgrades and maintenance.The deal also strengthens India’s defence partnership with France at a time when New Delhi is diversifying beyond traditional suppliers.The BEL–Safran HAMMER joint venture represents a quiet but important shift in India’s approach to air warfare. Precision, modularity and adaptability are now central to how air power is conceived and deployed.By moving HAMMER production to Indian soil, New Delhi is not merely acquiring a weapon. It is acquiring the ability to understand, modify and eventually design the tools of modern precision strike warfare.
