HYPERSONIC GLIDE VEHICLES

About:

• The missile in August “circled the globe before speeding towards its target, demonstrating an advanced space capability that caught U.S. intelligence by surprise.”
  
  
• The Chinese military launched a rocket that carried a hypersonic glide vehicle “which flew through low-orbit space before cruising down towards its target.”
  
  
• The missile “missed its target by about two-dozen miles”, but it “showed that China had made astounding progress on hypersonic weapons and was far more advanced than U.S. officials realised.”
  
  
• Only the U.S., Russia and China were developing hypersonic glide vehicles, that are launched on rockets and then orbit the earth on their own speed. They are difficult to track because unlike ballistic missiles, they “do not follow the fixed parabolic trajectory”.
  
  
• The test would post a big challenge to U.S. missile defence systems because “the weapon could, in theory, fly over the South Pole.” “That would pose a big challenge for the U.S. military because its missiles defence systems are focused on the northern polar route,” the report said.
