Chennai, Jan. 12 -- In a significant milestone, the Indian Institute of Technology-Madras (IIT-M) researchers have successfully developed and tested ramjet-propelled artillery shells designed to dramatically extend the range of conventional gun systems.

This marks a significant milestone in the indigenous development of defence technology, IIT-M announced here today.

The IIT-M innovation integrates a ramjet engine into an existing 155 mm artillery shell, replacing the conventional base-bleed unit.

Unlike rocket-assisted projectiles or incremental aerodynamic improvements, this approach enables sustained propulsion after theshell exits the barrel, significantly extending its reach while preserving the shell's destructive effectiveness on ...
