Researchers at IIT Madras have developed ramjet-propelled artillery shells that extend the firing range of conventional gun systems by 50%. The project integrates a ramjet engine into a 155 mm artillery shell, enhancing reach and maintaining effectiveness.

Initiated in 2020 with the Indian Army, the project has undergone multiple tests, including successful trials at the School of Artillery and the Pokhran Field Firing Range in 2025. The innovation addresses the challenge of increasing artillery range without sacrificing mobility or lethality, positioning India as a leader in defense technology. Ongoing refinements aim for full operational capability.
