As the Indian Army prepares to evaluate a new, locally developed Mounted Gun System (MGS), it is on the brink of a substantial transformation in its artillery capabilities. This 155 mm/52 caliber truck-mounted howitzer, which is designed for rapid deployment and exceptional mobility, was developed by the Defence Research and Development Organisation (DRDO) and manufactured by Bharat Forge Limited. It is distinguished by its “shoot and scoot” capability, which allows it to fire and reposition within 85 seconds. This feature renders it extremely effective in evading enemy counter-battery fire. This article extensively explores the MGS’s capabilities, technological advancements, and comparative analysis with similar artillery systems, including the French Caesar and Israeli ATMOS 2000, as well as its strategic significance in India’s broader artillery modernisation initiatives.
Key Features of the Indian Mounted Gun System (MGS)
The Indian MGS represents a significant advancement in indigenous artillery technology. It is a 155 mm/52 caliber howitzer capable of firing six rounds per minute and engaging targets at a distance of over 45 kilometres. The 52-caliber barrel length is a significant factor in the remarkable range and accuracy of the weapon, while the caliber denotes the diameter of the shells. The MGS can transition from moving to a firing position in a mere 80 seconds and return to mobility in 85 seconds when mounted on an 8×8 high-mobility vehicle. It is imperative to undergo this rapid transition to survive on the modern battlefield, where counter-battery fire is an ongoing threat.
The MGS is a direct evolution of the Advanced Towed Artillery Gun System (ATAGS), a project that was initiated by DRDO in 2013 to modernise the Indian Army’s artillery by replacing aging weapons with a state-of-the-art, indigenous solution
The MGS’s indigenous content is a critical component, with up to 85% of its components sourced domestically. This is consistent with India’s initiative to promote self-reliance in defence manufacturing, known as the “Make in India” initiative. The MGS is equipped with a number of cutting-edge technologies, such as a blast-resistant armored cabin for personnel protection, an onboard silent electric power system, and an integrated electronic controller that optimises operational efficiency. Additionally, it includes shock-absorbing stabilisers. Its robust design enables deployment across a wide range of terrains, from deserts to high-altitude regions, while its advanced fire control and navigation systems enable precise targeting and rapid response.
Evolution: From ATAGS to MGS
The MGS is a direct evolution of the Advanced Towed Artillery Gun System (ATAGS), a project that was initiated by DRDO in 2013 to modernise the Indian Army’s artillery by replacing aging weapons with a state-of-the-art, indigenous solution. The ATAGS is a 155 mm/52 caliber system that is unique because of its all-electric motors, which enhance reliability and minimise maintenance requirements. It is compatible with the Indian Army’s current ammunition supplies and boasts integrated fire control.
The Ministry of Defence placed a substantial order for 307 ATAGS units in 2025, with production being divided between Bharat Forge and Tata Advanced Systems. The MGS considerably improves the mobility and survivability of the ATAGS gun by adapting it to a truck-mounted configuration. The MGS addresses the necessity for rapid deployment and rapid repositioning, which are essential in contemporary, fast-moving combat scenarios, by mounting the cannon on a high-mobility vehicle.
The Modernisation of India’s Artillery
India’s strategy for modernising its artillery is multifaceted and comprehensive. The strategy involves standardising caliber and simplifying logistics by providing all artillery regiments with advanced 155 mm gun systems, including the ATAGS and MGS. The artillery arm’s reach and lethality are also emphasised by the modernisation drive, which prioritises the introduction of longer-range, precision-guided missiles and rockets.
Between the Indian MGS and international systems such as the French Caesar and Israeli ATMOS 2000, both similarities and distinctions are apparent. All three are truck-mounted howitzers with a 155 mm/52 caliber, which are engineered for rapid deployment and high mobility. The essential “shoot and scoot” capability, allows them to rapidly discharge and reposition, thereby preventing enemy counter-battery strikes
The K9 Vajra-T, a tracked 155 mm/52 caliber howitzer developed in collaboration with South Korea, is a prime example of a critical element of this strategy: the expansion of self-propelled artillery. The K9 Vajra-T, in conjunction with the MGS, is crucial for the army’s ability to respond to emergent threats, as it provides high rates of fire and rapid deployment capabilities. The MGS and comparable systems are intended to provide the qualities of mobility, survivability, and rapid deployment, which have been emphasised by the lessons learned from recent conflicts, particularly the Russia-Ukraine war.
MGS versus French Caesar and Israeli ATMOS 2000
Between the Indian MGS and international systems such as the French Caesar and Israeli ATMOS 2000, both similarities and distinctions are apparent. All three are truck-mounted howitzers with a 155 mm/52 caliber, which are engineered for rapid deployment and high mobility. The essential “shoot and scoot” capability, allows them to rapidly discharge and reposition, thereby preventing enemy counter-battery strikes. The precise targeting and effective use of NATO-standard ammunition are guaranteed by the advanced fire control and navigation technology that each system is equipped with.
Nevertheless, there are major differences. The French Caesar is capable of achieving ranges of up to 55 kilometres with rocket-assisted projectiles, which is slightly more than the MGS and ATMOS. However, the Indian system is superior when using conventional extended-range ammunition. The Caesar is more readily air-transportable and lighter in terms of mobility and weight, rendering it suitable for rapid overseas deployments. The Indian MGS is engineered for greater survivability and ruggedness, as it is heavier and specifically designed for the diverse and challenging operational environments of the Indian subcontinent.
The MGS’s development and deployment have significant implications for strategy for India. Initially, it represents a significant stride toward the nation’s independence in the field of sophisticated artillery technology, thereby decreasing its reliance on foreign suppliers
The ATMOS operates efficiently with a crew of four, while the MGS and Caesar typically require five to six personnel. Additionally, the crew requirements differ. The MGS is distinguished by its all-electric propulsion system, which reduces maintenance and improves reliability in comparison to conventional hydraulic systems. The MGS is predominantly Indian in its design and manufacture, which supports national self-reliance. In contrast, Caesar and ATMOS are products of the French and Israeli defence industries, respectively. The indigenous content of the MGS is likely the most significant difference. The Caesar is also distinguished by its operational experience, as it has been extensively employed in combat, including in Afghanistan, Lebanon, and most recently in Ukraine, where it has proven its efficacy in real-world scenarios.
Future Prospects
The MGS’s development and deployment have significant implications for strategy for India. Initially, it represents a significant stride toward the nation’s independence in the field of sophisticated artillery technology, thereby decreasing its reliance on foreign suppliers. India’s dedication to the establishment of a contemporary, indigenous defence industrial base is exemplified by the MGS and the ATAGS.
