does anyone has info on the missile that carried the HGV? SS-19?

Yup, SS-19. It will be used for first couple of dozen Avangards, they'll use ones they got from Ukraine as debt payment and kept in storage.

Also, they said that Avangard hit "target object" in Kamchatka, does that mean that it's accurate enough to hit individual targets and not just areas?

if CEP is less 50m why not? if something wights 1 tone and moves 7km/s it is enough I guess

From the side of bmpd, let us point out that this test launch was carried out by the UR-100N UTTH intercontinental ballistic missile, equipped with the hypersonic winged combat unit of the Avangard complex from the positional area of ​​the 13th Orenburg missile division of the 31st Rocket Army of the Strategic Missile Forces (open name Dombarovsky, Orenburg region),using a modified mine launcher MBR R-36M2.

As reported in October 2018 by the TASS agency, at the end of 2019, as part of the 13th missile division, the first regiment with UR-100N UTTH missiles with combat equipment of the Avangard complex, initially consisting of only two missiles, wiil be deployed in modified Silos of missiles R-36M2, with the subsequent completion of the composition of the regiment to the standard six launchers. In total, under the State Armaments Program for 2018–2027, by the end of 2027, it is planned to deploy two regiments of the Avangard complex with the UR-100N UTTH missiles (a total of 12 silos).

Presumably Avangard combat equipment is carried for both test launches, and for the intended combat deployment by the UR-100N UTTH missile from among 30 missiles of this type, received by the Russian side in 2002-2004 from storage in Ukraine and to the present time remaining in storage.

Borisov: tests of the Avangard complex proved its ability to accelerate to 27 machs

MOSCOW, December 27. / TASS /. The combat unit of the Avangard strategic missile system is capable of speeds of up to 27 Machs. About this on the TV channel "Russia-24", said Deputy Prime Minister Yuri Borisov.

"Recent tests have shown that he has reached speeds close to Macham 30. About 27 Mach, he picked up speed," said Borisov. “Practically at these speeds, no anti-missile can knock him down,” the deputy prime minister added.

According to him, the fundamental difference of the Avangard complex is that it is impossible to predict where it will be at the next moment in time. “He can maneuver both at the rate and in pitch, this is his fundamental difference. The antimissile defense is practically nullified. It is very difficult to detect this unit and moreover to hit,” said Borisov.

assuming it has no propulsion (then how it could maneuver?) still has kinetic enrgy.

Mach on 11,000km or higher -> 295 m/s

thus Ma 27 = 7,965 m/s while
for LEO you need 7,8km/s and for
\orbital speed on equator 7,9


so Avangard can actually orbit without descending to earth. I'n not sure about calculation its energy, guess better specialists are around here but looks at basics/:

specific orbital by 7,9km/s is ~31Mj/kg. You know potential + kinetic can exchange ( - adiabatic air compression in atmosphere at least - other dissipation's) so it can make a loong sufr.

BTW 30Ma = 8,850m/s

Because it does have propulsion

with such amount of energy I guess propulsion is to make maneuvers more then fly longer. Couple thousands of kilometers anyway- US space shuttle with 25Ma and 120km orbit required almost a halfs globe to glide...

Of course it has propulsion, where do you think the 'boost' in boost-glide comes from? It is a evolution of Topol-M/Yars, which were pure hypersonic gliders with no propulsion, but still maneuvered from the throw-weight momentum from it's rocket stages. Avantgarde's propulsion probably allows it to fly back in to LOE in FOB's launch profile, not giving it a couple thousand km range, but virtually unlimited range.

taking into account its speed is more than needed for LEO over equator FOB can be an alternative.

I would love to see the impact.

Borisov: the program of the Avangard missile system could have been closed four years ago

Deputy Prime Minister said that the developers persuaded Russian President Vladimir Putin to continue working and promised to achieve the necessary characteristics

MOSCOW, December 28. / TASS /. The development of the Avangard hypersonic block almost ceased four years ago, but the developers persuaded Russian President Vladimir Putin to continue working and promised to achieve the necessary characteristics. This was announced on Friday by Deputy Prime Minister Yuri Borisov on the Russia-24 TV channel .

"This complex was born quite hard. Four years ago, at a meeting of the Supreme Commander, the question was to continue or close this work, because, unfortunately, this is very difficult work ... convincing answer: “Give us one more chance.” And they used this chance, ”said Borisov

He noted that the test on December 26 was the third, it confirmed all the main declared characteristics.

Borisov recalled that the serial contract for the production of Avangard complexes was concluded in 2017. From next year, he should be armed.

UR100N has max 8,800t, not sure what is weight or Avangard but energy equivalent of 1 kg TNT ~ 1kg of mass ~4km/s in case of 8km/s you have 4x Ek. So at most 10 ton of TNT if my math is correct


E (1kg) TNT -> 4.184×106 J or 4.184 MJ


Ek=Etnt= 0.5mv2 -> v = sqrt(2Ek/m) if my math is correct it would be 2,893 km/s. Avangard is flying with 27Ma min (so 7,960 km/s).

So

E

avangard ~ 7,5xTNT mass equivalent. so 1,500kg Avangard would have energy of MOAB. Enough to kill CVN.

Mass of UR-100N is 105 t.

Avangard system is tested, said to be fully ready for deployment



On 26 December 2018 the Strategic Rocket Forces performed a test of the Avangard system that includes a hypersonic glide vehicle carried on a UR-100NUTTH/SS-19 missile. The launch, which took place at 12:59 MSK, was observed from the National Defense Control Center by the President of Russia and other officials. The test was said to be successful. It was also reported that the Avangard system has completed the program of tests and is ready for deployment in 2019.

The UR-100NUTTH missile that carried the vehicle was launched from a converted R-36M/SS-18 silo of the Dombarovskiy missile division (the one at 51.030849,59.690144). This silo has been used in earlier tests of the system (referred to as Project 4202). The vehicle reached its target at the Kura test site.

According to earlier reports, the deployment of Avangard will begin with two UR-100NUTTH missiles with the glide vehicle of the Avangard system will begin with two missiles deployed at Dombarovskiy by the end of 2019.

The history of Avangard/Project 4202 tests is a bit complicated. The vehicle, initially known as Yu-70, was tested four times in the 1990s and then it was mothballed until 2001. It was demonstrated to the Russian leadership in a test in February 2004 after which the development apparently got the green light (even though the test may not have been entirely successful). The next three tests - in December 2011, September 2013, and September 2014 (the evidence is mostly circumstantial for this one) - that involved a Yu-71 vehicle (built without Ukraine's participation) were probably not very successful as well. I was told that the designers had some problems with getting the vehicle to maneuver. This seems to be in agreement with what Yuri Borisov, deputy defense minister, said in a recent interview - the program was almost shut down "four years ago" (which would place it at the end of 2014). However, the designers asked for another chance to prove that the project is viable and they got it.

After that decision, there was a known test in February 2015 (probably unsuccessful), and two in 2016 - in April and in October. U.S. intelligence sources were quoted as saying that there was another (unsuccessful) test in October 2017, but this report does not seem very reliable - all 2017 ICBM launches have been accounted for and Borisov said that the most recent test of Avangard was the third one (I assume it was the third successful).

Here is my attempt to bring everything in one table:
Date Test site Comment
28 Feb 1990 Baykonur Appears to be the first test of the Yu-70/102E vehicle. Did not involve separation of the vehicle from booster. 15A35P launch
29 Mar 1990 Baykonur Yu-70/102E vehicle. Did not involve separation of the vehicle from booster. 15A35P launch
26 Nov 1991 Baykonur 15A35P launch
28 Jul 1992 Baykonur 15A35P launch
27 Jun 2001 Baykonur 15A35P launch
18 Feb 2004 Baykonur Demonstration of the Yu-70/102E vehicle. UR-100NUTTH launch during a strategic exercise. 15A35P launch. Reportedly unsuccessful.
27 Dec 2011 Baykonur The first test of the Yu-71 vehicle of the Project 4202 program. 15A35P launch
27 Sep 2013? Dombarovskiy Reportedly unsuccessful
Sep 2014? Dombarovskiy Not confirmed
26 Feb 2015 Dombarovskiy Reportedly unsuccessful. 15A35P launch
19 Apr 2016 Dombarovskiy Reportedly successful. 15A35P launch
25 Oct 2016 Dombarovskiy Reportedly successful
Oct 2017? Dombarovskiy Reported, but not confirmed
26 Dec 2018 Dombarovskiy Reportedly successful

In any event, everything appears to be ready for the first two Avangard launchers at Dombarovskiy in 2019. The total of 12 missiles are expected to be deployed there by the end of 2027, which confirms that it's largely a niche capability. There are persistent rumors about Avangard gliders being deployed on Sarmat ICBMs - as many as three on a missile - but I am a bit skeptical about that.

AvangardLaunchCover.pngP.S. An interesting detail that can be seen at 0:05 on the video of the launch - the opening silo cover has something like a piece of cloth (тряпочка) attached to it. My guess is it's a cover of the missile container that is being removed as the silo opens. But the removal method doesn't seem particularly elegant.

P.P.S. The glider is said to have reached speed of 20M or even (according to Borisov) 27M. This sounds impressive (and in fact it is), but we should keep in mind that the vehicle is flying at altitudes of 70-80 km. The speed of sound there is about 290 m/s, which is less than 340 m/s at the sea level (NASA has a nice calculator). So, 20M would be 5.8 km/s (27M is about 7.8 km/s).

Borisov reveals that Avangard was almost cancelled 4 years ago, but general designer asked Putin for another chance.

An interesting question about (recently launched with much fanfare) Avangard. What is its status under New START? Is it a prototype? Does Russia report its launches? As SS-19 launches? How does it report that silo at Dombarovskiy?

Well technically Avangard is a payload and not an ICBM, so it should not really matter...

nice dramatization of story, personally I dont believe - hypersonic tech it too important just ot let it go. They would redesign whatever but money owuld be supplied as needed.

Dont know why the other guy is skeptical about Avangard being the payload of Sarmatian.

Dont worry Arrow they will be way more than 12 Avangard in 2027.

Funny that for years you asked about the Zirkon (you asked many times on many topics) but when the Americans sources confirm the successful tests you dont say a word!

Sadly for you the gap between western and Russian weapon technology will only grow

I know it's pretty much considered Vaporware today, but i wonder if it's possible here, considering these extreme speeds.

How can a set in stone principle of astrophysics be considered vaporware? To the benefit or determine of the astrophysicists at hand, super-heated plasma clouds that form around hypersonic objects will absorb a large amount of radiowaves directed towards it's direction.
