Comments by "Reecom98" (@reecom9884) on "Russians prepare for combat hypersonic 20,000 mph Avangard 'meteorite' missile" video.

In the video notes: "The missile with a hypersonic glide vehicle is fired outside the earth’s atmosphere before striking any target..." missiles travelling outside the earth's atmosphere will go hypersonic speeds. During WW2 the German V-2 rockets reached a speed of Mach 4.3 in ascent, and then became hypersonic in descent, clearing Mach 5 while still in the thin air and reducing speed in the thicker air in the lower atmosphere as they struck targets in England.

@surindernagi1406 The US space shuttle was a hypersonic glider at about Mach 22 on re-entry to land on a runway. The space shuttle would have to do big “S” turns to lose speed to land. Once hitting the thick air, the space shuttle would ionize the air particles creating a communication blackout. The Russian Avangard hypersonic missile would be able to big “S” turns at hypersonic speed based on a program flight path, but wouldn’t able to detect missiles fired at it due to the ionized cloud around it and avoid them.

@surindernagi1406 There is no such thing as radar light spectrum waves. The radar return signals would show a undefined plasma cloud and not what's in the cloud and the IR spectrum would show a high heat source like what you see as a meteorite burns through the atmosphere. What are you talking about the French Rafale using a plasma field?

@mariopiazzolla9105 An ICBM is not an intercept missile that targets other missile like an Anti-Ballistic Missile (ABM), an ICBM carries a nuke. No country has verified destroying a "hypersonic" missile in a test.

@bear76009 The Hypersonic missile is an air breathing missile using a SCRAM jet engine. The trajectory would be flatter than a ballistic trajectory ICBM which has to have more of a downward flight path with limited maneuverability with no engine.

@surindernagi1406 Plasma stealth technology is like “Cold Fusion”; it is possible but hasn’t been made for practical application for aircraft. The detection and tracking of missile launched hypersonic missile will be space based satellite IR detection of the heat launch from the silo. The extreme heat from the hypersonic missile that ionized the air will be tracked by the IR satellite as it flies. Ground station radar’s range and altitude is limited by the Earth’s curvature and the height of the radar station above ground, satellites have much better coverage and would give earlier warning.

@bear76009 Hypersonic missiles flies in thin air, the terrain following or sea skimming in the dense lower atmosphere would would prevent the SCRAM jet engine from working.

@bear76009 I got confused with the Russian Hypersonic missile and their Avangard ICBM having a lifting body configuration (i.e. some kind of lifting shape body) on the warhead allowing it more maneuverability than shifting the center of gravity of the warhead for changes in flight path. It is not powered but the more maneuvers it does, it loses speed.

@surindernagi1406 The multiple reentry ballistic warhead has a limited maneuverability less than the hypersonic gilder.

@bear76009 The US Patriot missile system is a theater of operation missile and attacks in the terminal entry phase over the protected country. No country attacks in the boost phase, it would be directly over the enemy country.

@chilledolay4065 He was talking about the V1 "Buzz" bomber. No one ever heard the V2 since it went in a ballistic trajectory.

@myhouse97 The V2 once the fuel was gone the entire rocket body was intact as it hit the ground. The Russian Avangard ICBM having a lifting body configuration (i.e. some kind of lifting shape body) on the warhead which separates from the body of the rocket once the fuel is gone.

@F.O.U.N.D.E.R The Russian Hypersonic missile and their Avangard ICBM having a lifting body configuration (i.e. some kind of lifting shape body) on the warhead allowing it more maneuverability than shifting the center of gravity of the warhead for changes in flight path. It is not powered but the more maneuvers it does, it loses speed. The US also is developing a hypersonic ICBM warhead with a lifting shape body; the arms race never stops. How good the Avangard warhead is based on interpretation. The Russian Su-57 was supposed to be a 5th generation stealth fighter better than the US F-22, but the Russians never use it in Ukrainian airspace.

@F.O.U.N.D.E.R U.S. successfully tests pair of Lockheed hypersonic missiles..." 13 Jul 2022 Reuters. These are SCRAM jet air-breathing missiles. The Russian SCRAM jet hypersonic missile was use by Russia to destroy an Ukrainian ammo depot, apartments, and shopping center early in the war never used again, since it was very expensive.
