20 Minutes of Sustained Hypersonic Flight — DRDO Just Did It #technology #military #shorts

[00:00:00]DRDO has successfully tested a hypersonic scramjet engine for 1,200 seconds. That's 20 full minutes.

[00:00:07]Now, at first, that may not sound revolutionary. After all, America, China, and and Russia already have hypersonic weapons. So, what's special here?

[00:00:17]Most hypersonic systems people hear about are ballistic missiles, boost glide vehicles, or short duration demos.

[00:00:24]But sustained air-breathing hypersonic propulsion, that's a completely different challenge. Because making something go hypersonic for a few seconds is one thing. Keeping it stable, fueled, and controllable for 20 minutes at Mach 6 or Mach 8, that's the hard part.

[00:00:40]Now, let's understand the scale. Mach 6 is roughly 120 km per minute. Mach 8, nearly 160. So, a hypersonic cruise vehicle sustaining those speeds for 20 minutes could theoretically enter the 2,500 to 3,300 km range class. That's strategic range territory.

[00:01:01]For comparison, BrahMos, up to 800 km.

[00:01:05]Russia's Zircon, roughly 1,500 km.

[00:01:10]Agni 3, 3,000 km plus. Even LRASHM, up to 1,500 km. For context, America's Waverider achieved around 210 seconds.

[00:01:22]DRDO's reported duration, nearly six times longer. And that is why this matters. Because in hypersonic warfare, top speed alone is not the breakthrough.

[00:01:32]Sustained propulsion is.
