The Indian Army is on track to become the first in the world to deploy ramjet-powered 155mm artillery shells. Being developed by IIT Madras, in collaboration with the DRDO, this technology significantly extends the reach of conventional artillery while maintaining high lethality.
Key Technical Capabilities
- Extended Range: The ramjet shell increases the strike range by 30–50% over standard ammunition. While traditional shells for systems like the ATAGS reach roughly 45 km, the ramjet variant can strike targets up to 80 km away.
- Supersonic Ignition: The shell functions as an "air-breathing engine" that does not require an internal compressor. It uses the high-speed forward motion of being fired from a cannon to reach Mach 2, at which point the ramjet ignites and sustains its flight.
- Retrofitting & Compatibility: The technology is designed to be retrofitted onto existing 155mm shells, making it compatible with a wide range of Indian artillery guns, including the Dhanush, K9 Vajra-T, and M777 howitzer.
- Precision Guidance: To maintain accuracy at extended distances, the shells incorporate a Precision Guidance Kit (PGK), utilizing India’s indigenous NavIC satellite system.
- Testing Milestones: Successful trials have been conducted at the Pokhran Field Firing Range in Rajasthan as of early 2025.
- Operational Timeline: Preparations for operational use are in the final stages. Initial squadrons are projected to begin entering service by late 2026 or 2027, aligning with the broader induction of ATAGS units into the Army.
- Manufacturing: The project has been approved by the Army Technology Board, and Munitions India Limited (MIL) is designated to handle large-scale production once final validation is complete.
