The 220 ton RS-28 Sarmat (Satan 2, or SS-X-29) is a heavy ICBM designed for delivery of next gen nuclear warheads, which Russia “formally” began designing in 2009 (actual 2002-2003), for next gen warheads produced as early as 2001/2002 (about the same time Putin began heavy re-nuclearization of Kaliningrad - official yet unofficial of course), literally in violation of every Nuclear Treaty since Reagan.
This was the reason Bush 43 ordered short suspense Patriot, THAAD, and AEGIS Ashore missile defense networks put in place early on.
Of course, Putin told Obama to cut off missile defense, so Obama happily complied.
Trump is the one who order completion, and saw active/working anti-nuclear defense operable in Central and Eastern Europe.
Anything faster than 3,836 mph (or Mach 5) is hypersonic.
The RS-28 Sarmat has a top speed of just under 16,000 mph (just under Mach 21), with a range of 11,000 miles.
Both the speed and distance are near typical to all ICBM’s, and all CCCP and US ICBM’s really since first gen ICBM’s.
While ICBM speeds are multiple’s of most “hypersonic’s”, and the ICBM’s are certainly hypersonic — *ICBM’s are not the class of missile being referred to with current “hypersonic’s”.
Modern hypersonic’s are typically referring to scram and ram jet engine powered missiles, tuned to rely on the forced gas/very high ptessure (to burn), and light gravity ratio of between 85,000 to 110,000 ft altitude to operate. Conversely, ICBM’s are “LEO” (low earth orbit), typically travelling well above the Stratosphere.
While the hypersonic tech is advancing rapidly and globally (and yes, Obama and HRC knowingly transferred hypersonic tech to Putin through the Skolkovo, receiving at least $145.5 million in return), technically ICBM’s are multiples faster than “hypersonic’s”, with greater range.
By the way, you won’t find this on the net, but Russia was testing this long before 2018. That number is about 9 years after “stuff”.
Good background info. Much appreciated.
Also,The Sarmat has a range of 18,000 kilometers or just over 11,000 miles and can fly unpredictable routes while it is able to bypass missile defense areas. The missile has the ability to fly over the North and South Pole and even approach targets from directions that are not envisaged for interception.
Most worrisome for the U.S. military is that the Sarmat can be equipped to carry a number of reentry vehicles, including hypersonic Avangard gliders.
Anyway you look at it, those thinking we should get into a nuclear volley with Russia are absolutely crazy.
