Russian hypersonic weapons are a game changer?

Russian hypersonic weapons are a game changer? By Alex Krainer.

It was in 2018 that Vladimir Putin took the stage to present Russia’s new hypersonic weapons. The term “hypersonic” refers to missiles that fly at speeds of 5 mach [5 times the speed of sound] and higher. …

Russia is the only country in the world that has deployment-ready hypersonic missiles — not one but three types: Zircons, Kinzhals and Avantguards. …

In World War 1, tanks were the game changing military technology. Since World War 2, it’s been the air-force. Aircraft carrier strike groups have been an irresistible force wherever they travelled, dominating the seas ever since. But hypersonic precision missiles have rendered that force obsolete overnight.

Today’s ABM [Anti-Ballistic missile] systems are only effective against missiles flying at speeds up to mach 3.5.

Russia’s new Kinzhal missile flies at speeds of mach 12 to mach 15 and nothing in western defensive arsenals can stop its strike…. The Kinzhal flies at altitudes of between 20 and 40 km, with a maximum range of 2,000 km. When above target, it dives perpendicularly and accelerates to 15 mach, generating enormous kinetic energy in addition to its explosive payload. …

The first Kinzhal strike, delivered one month after the beginning of hostilities in Ukraine, was perhaps the most significant: Russian forces targeted a large weapons depot in Ukraine which had been built during the Soviet times to withstand a nuclear strike. It was buried 170 meters (over 500 ft) underground and protected by several layers of armored concrete. … That first strike with a single Kinzhal missile destroyed Ukraine’s nuke-proof underground weapons depot. This was a message for the west.

The Kinzhal was developed with the express purpose of destroying aircraft carrier strike groups. If it could destroy a warehouse built to withstand a nuclear strike, it can cut through an aircraft carrier like a hot knife through butter. …

Only the Russians have operational hypersonic missiles:

The critical issue with hypersonic weapons are the extreme temperatures reached during hypersonic flights on the surface of missiles, which can cause them to break apart mid-flight. Russia is the only nation that has developed special materials that enable the missiles to withstand this stress, so their flight can be controlled throughout its trajectory and delivered with pinpoint accuracy.

Western intelligence estimated that Russia had some 50 Kinzhals at the start of the war in Ukraine, and thus far it has used only 9 of them. Last week, they fired six Kinzhals in a single salvo. That too, was a message. … United States have 11 aircraft carrier strike groups. Of these, fewer than half will be active at any one time (while others are in dock for maintenance, or in preparation). Firing six Kinzhals in one go is military-speak for, “we have the capability to sink ALL of your aircraft carriers at once.” …

Russia has the capacity to build about 200 Kinzhals per year and now has means of delivering Kinzhal and Zircon missiles anywhere from aircraft, ships and submarines. In addition to destroying aircraft carriers, they can also destroy NATOs ABM missile sites.

But, maybe they are not a game-changer (see from 12 minutes, especially):

When the Kinzhal (or any hypersonic missile) dives down into the thicker air under 30,000 feet to hit a target, it is slowed down to mach 2 – 3 and its scramjet engine then stops working. So then it is unpowered and moving ballistically (and therefore predictably), and can be defended against with existing missile defenses.

So, scary story, but probably not a game-changer.
