What the Chinese and Russians mean when they say Hypersonic Gliders is the red trajectory in the pic. What Americans mean when they say they already did hypersonic weapons 50 years ago is the blue trajectory in the pic.

Entire American missile defense is based on the assumption that the whole world uses the blue trajectory against them.

But in the last 10 years the whole world is using the red trajectory, and Americans are already left naked under the skies.

To make it worse the English speaking media does not explain it properly except in rare instances like the pic.

It changes everything because American hegemony is based on their access to two oceans, and strong navy to do naval blockades. Because ocean transport is still the cheapest for goods. But being able to do naval blockades using a navy + two ocean is not that relevant anymore. Because the hypersonic Gliders can reach any aircraft carrier in a few minutes.

FAQ

• ICBM like Minuteman II are faster than Hypersonic Gliders, so what’s the threat?
  • Answer: When you play baseball even though the ball moves faster than you can run, since the ball moves in predictable ways you can catch it. Similarly even though ICBMs move faster than hypersonic gliders, it is easier to catch an ICBM. Hope that makes it clear. Minuteman 2 moves at a peak speed of Mach 23 which is hypersonic, but it easier to intercept a Minuteman 2 because it has to follow orbital physics for its trajectory.
• What about a Pershing II?
  • Pershing II only has a range of 1,100 miles (1,770 km).
  • Hypersonic Gliders go the same distance as an ICBM around the Earth but closer to the Earth.
  • The distance from Beijing to San Francisco is 9497 km.
