Context:
The Indian Army is set to become the first armed force in the world to operationally deploy ramjet-powered artillery shells for its 155 mm artillery guns, marking a major leap in long-range conventional firepower.
What is it?
Ramjet-powered artillery shells are advanced 155 mm projectiles equipped with an air-breathing ramjet propulsion module. After being fired from a conventional artillery gun, the ramjet sustains thrust in flight, significantly extending the shell’s range without altering the gun system itself.
About Ramjet Technology
A ramjet is a type of air-breathing jet engine with no moving parts, designed to operate efficiently at supersonic speeds.
- Does not carry its own oxidiser
- Uses atmospheric oxygen for combustion
- Becomes efficient only after the projectile reaches high speed (provided by the gun launch)
Key advantage: Much higher efficiency and range compared to rocket-based propulsion for artillery shells.
