2,400 Miles in Minutes? No Sweat! Hypersonic Weapon Passes ‘Easy’ Test
For a test of a hypersonic weapon flying at eight times the speed of sound and nailing a target thousands of miles away, this was a relatively simple demonstration. But it worked, and now the military is a small step closer to its dream of hitting a target anywhere on Earth in less than an hour.
The last time the Pentagon test-fired a hypersonic missile, back in August, it live-tweeted the event — until the thing crashed into the Pacific Ocean. This time around, it kept the test relatively quiet. The results were much better.
To be fair, this was also an easier test to pass. Darpa’s Falcon Hypersonic Technology Vehicle 2 — the one that splashed unsuccessfully in the Pacific — was supposed to fly 4,100 miles. The Army’s Advanced Hypersonic Weapon went about 60 percent as far, 2,400 miles from Hawaii to its target by the Kwajalein Atoll in the South Pacific. Darpa’s hypersonic glider had a radical, wedge-like shape: a Mach 20 slice of deep dish pizza, basically. The Army’s vehicle relies on a decades-old, conventionally conical design. It’s designed to fly 6,100 miles per hour, or a mere eight times the speed of sound.
