Why Is the World Watching India’s 8x Speed Hypersonic Missile Test?

India has joined the elite hypersonic missile club with the successful test of the ET-LDHCM (Extended Trajectory Long Duration Hypersonic Cruise Missile) under DRDO’s Project Vishnu. With a staggering speed of Mach 8 (8x the speed of sound) and a 1,500 km strike range, this missile surpasses existing systems like BrahMos. But what makes it a strategic game-changer for India’s defence?

What Makes ET-LDHCM Special?
1. Hypersonic Speed & Stealth
Travels at 8x the speed of sound (~11,000 km/h), making it nearly impossible to intercept.
Uses a scramjet engine, which relies on atmospheric oxygen, eliminating the need for heavy oxidizer tanks.

2. Extended Strike Range
1,500 km range (compared to BrahMos’ 450 km), allowing deep strikes into enemy territory.
Multi-platform launch: Can be fired from land, air, or naval systems for tactical flexibility.

3. Precision & Payload Versatility
Mid-flight course correction ensures accurate hits on high-value targets.
Can carry both conventional (1,000–2,000 kg) and nuclear warheads, enhancing deterrence.

4. Thermal Resilience
Engineered to endure 2,000°C+ temperatures during flight, ensuring stability at hypersonic speeds.

5. Strategic Deterrence
Counters China’s hypersonic advancements and strengthens India’s stance against Pakistan.
Positions India alongside the US, Russia, and China in hypersonic technology.
