New Russian heavy ICBM - Sarmatian

I read on bmpd that the combat starting positions of the Sarmat ICBM will be covered by the "Blockade" active protection complex or its modernized version: https://demchenko2000.livejournal.com/1275.html

found some cool sources.

"Short boost phase: The short-boost-phase claim is somewhat puzzling, because the Sarmat, like the Voevoda, uses liquid fuel.11 Liquid fuels tend to produce longer boost phases than solid fuels.12 It is hard to be definitive about what is behind the shortboost-phase claim, but there is substantial reporting suggesting the new first-stage engine for the Sarmat, the PDU-99,13 is being designed to lower the signature and/ or increase the thrust and boost speed of the Sarmat. Reporting consistently names Energomash as the engine design agency; however, whereas many report the PDU99 is a variant of the engine used on the current Voevoda,14 others claim it is a more advanced pulsed-detonation engine.15 Some reports assert the new engine will hyperaccelerate the Sarmat into orbit, reducing the infrared signature of the launch as well as the time available for earlywarning satellites to detect such a launch.16 Since infrared signature is closely related to engine type, fuel composition, burn time, rocket geometry, chamber parameters, and flight conditions,17 it is possible that a new engine and/or new fuel could cause the boost phase to be harder to detect and characterize. It is widely reported the PDU99 was tested in August 2016, although no detail is given about the engine.18 Later that same month, it was also reported, a full-scale pulse detonation engine was tested by the Russian Advanced Research Foundation19 supported by Energomash. The Advanced Research Foundation engine was said to employ clean fuel and obtain high thermodynamic efficiency while providing lower cost and increasing the payload weight for space missions."

Other sources have suggested that avangard uses a scramjet, than another source states special engine. https://naukatehnika.com/vrashhayushhijsya-detonacionnyj-dvigatel.html

"To date, GE Research has already solved many fundamental problems related to hypersonic transport. For example, the company develops ceramics that can withstand the high temperatures created by a rotating detonation engine because it contains an endless explosion. Such innovations will return commercial travelers to supersonic aircraft by 2025. The U.S. Department of Defense announced earlier this year that hypersonic transportation should be a top priority. The Pentagon is pushing Russia, which has a Vanguard equipped with a special engine, and China is also claiming a powerful program of hypersonic missile research."

Avantgarde is an unpowered boost glide vehicle, no scramjet, no engine.

The missile with the hypersonic engine, possibly a scramjet, is the Zircon, not Avangard.

Sarmat will likely have Avangard boost glide warheads in at least some versions in order to enable it to be resistant to ABM systems.
These are basically warheads which can glide across the atmosphere after being boosted by a rocket. They don't have any propulsion.

TBH there is no way to know for sure. The "generic" HGV is an unpowered vehicle, but who can say for sure if Avangard doesn't have scramjet as a sustainer to extend its performance envelope? Data regarding its performance is obviously classified, and the US isn't about to show its hand and reveal what it knows (or doesn't).

Zircon is most definately scramjet powered, so Russia possesses workable engines. The question is do they have an engine that can work at very high mach numbers in the rarieifed mesospheric atitudes?

That seems highly unlikely. AFAIK a detonation or scramjet engine requires oxygen to operate. It is meant to operate inside the atmosphere. That is how you get the performance increase over rockets. By not having to carry the oxidizer. The Avangard might have some small thrusters to ensure it can maneuver better but it's highly unlikely it will have a powerful airbreathing engine in it. Particularly at those speeds scooping up air is pretty damn hard. If you go deep inside the atmosphere to scoop it up you will get really high friction heating which will melt most materials. Avangard is supposed to work at much higher speeds than Zircon. Allegedly Mach 27 vs Mach 8.

Yes, it likely glides across the top of the atmosphere and avoids the denser air until it starts the descent to the target.

How is the Avangard able to achieve such high speed for most of the flight. If there is no engine mayby only correct, each maneuver will waste a lot of energy. In addition, it flies on a low trajectory, where there is some atmosphere, which at this speed causes huge friction. In such a situation, its speed will be much lower than 27M in the terminal phase ?

Well, one possibility which would require minimum thrust would be to skip around the upper layers of the atmosphere. Link of it like throwing a flat pebble over the surface of the water.

It works like the Htv-2 from DARPA, that achieves Mack 22, no scramjet.
The only difference between them is Avangard works.

Today or tomorrow (June 10 or 11, from 06:00 to 12:00 UTC) an ICBM is scheduled to be launched from the Plesetsk test site. The allotment of zones for the fall fields suggests the launch of the 15A28 "Sarmat" ICBM.

Watch out Biden!

Today "Cobra Ball" did not go to Kamchatka. Judging by the fact that NOTAM Y6348 / 21 has been removed from the AIS to the restricted area adjacent to the ban over the Kura range, the launch (or its attempt) took place yesterday and today nothing will fly.

I wonder what flew yesterday?

A new intercontinental missile is expected to be launched at the Russian test site

KRASNOYARSK, June 24. / TASS /. Flight design tests of the Sarmat intercontinental ballistic missile (ICBM) are scheduled for the third quarter of 2021. This was announced to TASS by the general director of the Krasmash plant, Alexander Gavrilov.

"The first flight tests will take place this year. The third quarter is planned," Gavrilov said.

MOSCOW, August 4. /TASS/. The first launch of Russia’s advanced Sarmat silo-based intercontinental ballistic missile (ICBM) is scheduled to take place this fall, a defense industry source has told TASS.

"The first launch of Sarmat as part of flight development tests will presumably take place this fall, the second one - in late 2021," the source said.

TASS did not receive an official confirmation of this information at the time of the publication.

Krasmash plant Director General Alexander Gavrilov told TASS in June that Sarmat flight tests had been scheduled for the third quarter of 2021.

Sarmat is to replace R-36M2 Voevoda missiles, which have been the most powerful in the world and operational since 1970s. Sarmat considerably exceeds the predecessor. Some of its characteristics were disclosed at Army-2019 forum. The new missile weighs 208.1 tons, the payload is close to 10 tons and the fuel is 178 tons. The range of Sarmat is 18,000 kilometers.

It can fly by unpredictable routes and bypass missile defense areas. It can fly over the North and South Pole and approach targets from directions that are not envisaged for interception. Sarmat can carry a line of reentry vehicles, including hypersonic Avangard gliders.

Military experts say that Sarmat missiles will help deter the United States’ plans of deploying its global missile defense system.

Shoigu: Krasmash is ready to fulfill the contract for the supply of Sarmat ballistic missiles to the army. 

Krasnoyarsk Machine-Building Plant is ready to fulfill a long-term contract for the supply of the latest Sarmat intercontinental ballistic missiles to the Russian Armed Forces, Russian Defense Minister General of the Army Sergei Shoigu said on Friday.

On Friday, the Minister visited Krasmash, where he inspected the company's production facilities and heard a report from the company's management.

"We have just reviewed all issues related to new types of weapons. We looked at how Krasmash is ready to fulfill a long - term contract for one of the most formidable weapons that our country should possess-the Sarmat missile. We have full confidence that Krasmash will fulfill its tasks" – the Minister said at a meeting with the plant's staff.

The minister added that back in 2019, he could not say with certainty that Krasmash was able to provide this program, but today he is convinced of this.

Source: two test launches of Sarmat ICBMs are planned to be completed by the end of 2021

MOSCOW, October 11. / TASS /. Two test launches of the newest liquid-propellant intercontinental ballistic missile (ICBM) Sarmat are planned to be completed by the end of 2021, the first of them in November. This was reported to TASS by a source in the military-industrial complex.

"Within the framework of flight design tests (LKI), it is planned to carry out two launches of Sarmat ICBMs from the Plesetsk cosmodrome in 2021, the first in November," he said.

According to him, in 2022, LKI missiles will continue, then state tests will be carried out so that by the end of the year the first regiment with missiles of this type will take up combat duty as part of the Strategic Missile Forces (Strategic Missile Forces).

TASS has no official confirmation of this information.

No official confirmation? Not sure it's worth reporting then, but its plausible at least.

Instead of two pledged tests this year, there will be only one.  For several years now, the Sarmat missile's flight tests have been postponed.  Is something wrong with the project.  This is an extremely important project because Sarmat is to replace the old R 36M2, which has more than half of the strategic nuclear arsenal of about 460 warheads.

They seem to be doing better with the development of hypersonic weapons than with the new heavy ICBM. Nothing is known about the progress of work on Poseidon and Burevestnik.

Nothing is wrong, at least nothing that is unusual for such complex projects.  

Nothing is known about the progress of work on Poseidon and Burevestnik because Russia has absolutely no reason to tell the feckless bastards in the West what they are doing, or when it will happen.  The West are the self-avowed enemies of Russia, and now increasingly, of China.  That kind of stupid arrogant bullshittery has consequences, and just one of those will be Russia (and China) building new advanced weapons which the west has no counter against.

Cause.  Effect.  Its shrouded in secrecy, and we have no-one to blame but our own idiot "elites".

Yes, these are complex projects, but Russia has extensive experience in the construction of ICBMs. However, something is happening, there are problems since they have been postponing flight tests for 3 years. It is not known whether it will fly this year. Of course, there are always problems, but in this case something is going nue, because they assumed the commissioning in 2020.

Couple of weeks delay at the end of the year can easily push test to next year

There would be a problem if all those test fail. Just wait and see.
