IIT Madras Develops Ramjet-Assisted Artillery Shells Extending Gun Range by Up to 50%

IIT Madras has developed and successfully tested ramjet-assisted 155 mm artillery shells that extend the firing range of existing gun systems by 30 to 50 percent without reducing lethality. Integrating a ramjet engine in place of the conventional base-bleed unit, these shells sustain propulsion after firing, enhancing range significantly. Trials with various artillery guns, including ATAGS, Vajra, and Dhanush, demonstrated ranges up to 70 km. The innovation, conducted in collaboration with the Indian Army, offers a cost-effective upgrade and aligns with India's indigenous defence goals.
