Comment bmpd. Thus, by the end of 2016, armed with Russian Strategic Missile Forces must be presumed, 96 launchers for the missile complex RS-24 "yars" (presumably, 78 silo and 18 mobile).

Plus the 60 silo and 18 mobile Topol-M. Getting close to 200 modern ICBM's.

Four new Russian Missile Forces with Yars ICBM sytems on combat duty

Russian Defense Minister Sergei Shoigu stated that four new regiments of the Russian Strategic Missile Forces, were put on combat duty in 2016 said Thursday.


Four new regiments of the Russian Strategic Missile Forces, armed with Yars intercontinental ballistic missile (ICBM) systems, were put on combat duty in 2016, Russian Defense Minister Sergei Shoigu said Thursday. "Four new regiments, armed with mobile Yars missile systems, were put on combat readiness," Shoigu said.

"Four new regiments, armed with mobile Yars missile systems, were put on combat readiness," Shoigu said.

The RS-24 Yars also known as RT-24 Yars, NATO reporting name: SS-29) is a Russian MIRV-equipped, thermonuclear weapon intercontinental ballistic missile first tested on May 29, 2007, after a secret military R&D project, to replace the older R-36 and UR-100N that have been in use for nearly 50 years. RS-24 is a missile that is heavier than the current Topol-M, and which some reports say can carry up to 10 independently targetable warheads.

The assumption that it has the same solid fuel as the Topol M is not backed up by anything. It
has been a long time since the Topol M was introduced. Chemical engineering moves on. You
can see this evolution by comparing Soviet and relatively recent solid rocket fuel characteristics.
For the same weight the newer Russian variants are twice as energetic.

Russia is not going to be giving out the fuel specifications for general consumption. It is a high
level military secret and Wikipedia level analysis is worth squat.

According to the START declaration RS-24 has that same throw weight, missile weight and range as the Topol M. This is MIRV version Topol-M. So propably RS-24 use very similar solid fuel.

Russia fires Yars ICBM at test target 6,000 km away

Russia has successfully completed a test launch of a new-generation RS-24 Yars intercontinental ballistic missile from a silo at the Plesetsk Cosmodrome in northern Russia.
“The main purpose of the launch is to confirm the reliability of rockets of the same class. The warheads successfully reached their target – the Kura testing range in Kamchatka. All aims of the test were achieved,” said a statement from Russia’s Defense Ministry.

Yars launch in September tested parallel deployment of warheads



It appears that we have an answer to the question of what kind of "experimental warheads" were tested in the September 12 Yars launch. And a confirmation of a guess made on Twitter by @artjomh shortly after the test. The image above is from that post - it's from a textbook they use at the Bauman University. According to The Diplomat's Ankit Panda, Russia tested "an independent post-boost vehicle (IPBV) configuration for a three-warhead version [of the Yars ICBM]." The Bauman textbook calls it "an RV with independent (parallel) deployment." As can be seen from the image, each RV is sitting on top of its own mini-bus, which is different from a more common configuration, when one bus deploys RVs one after another.

There is no doubt that this project was justified as a response to missile defense and it indeed could be an effective countermeasure, especially if an RV is attached to its mini-bus through most of the midcourse phase (which may or may not be the case). Even small maneuvers would make it difficult for an interceptor to catch the RV. But probably not impossible - a lot would depend on the divert capability of the mini-bus and the interceptor.

There is no free lunch, of course. Small mini-buses are probably heavier than one big one, so a missile would carry fewer warheads - three in this case instead of four that Yars is believed to normally carry. And these three warheads are probably smaller (although it hardly matters unless you try to hit missile silos, which is not Yars' mission). On the balance, I think this could be a useful anti-missile defense capability, but it's not a game changer. As far as effectiveness is concerned, it's hard to beat an old proven countermeasure - more warheads and decoys. But it is also a good illustration to the futility of the entire missile defense enterprise - it is much easier for "rocket men" to come up with new ideas than for missile defense to find a way to respond.

I wonder in parrell seperation system the Independent BUS with Warhead can re-enter the atmosphere at any phase of flight by that I mean mid-course or just post 1st or Second stage.

That would be an amazing achievement because you would not know what the target is and in which part of flight might one of the warhead seperate and re-enter the atmosphere manouvering its way in space

I wrote my opinion on Russian Forces on why its a game changer hope they post it

Yars launch in September tested parallel deployment of warheads

http://russianforces.org/blog/2017/10/yars_launch_in_september_teste.shtml

It would be a game changer to the extent that it would allow the RV to detach in mid-course of flight or post 3rd stage or for that matter even after boost phase ends and 2nd stage starts.

It depends on the target one chooses and in which phase of flight , An independent guidance/propulsion/warhead means you can let the RV fly all the way to target with greater accuracy , maneuverability and during any stage of BM trajectory

The Decoys/Jammers would still be part of the flight should they choose to burn all the 3 stages for longest range and let the 3 RV separate post 3rd stage burn out , it gets rid of heavy PBV and afford more space to carry larger RV but in less numbers

Separate buses would allow gliders to enter the atmosphere at different points in the trajectory which means the defence problem becomes harder... in fact you could deceive the enemy and release a glider short but at a shallow angle and high speed so it skips off the atmosphere and back up into space... any interceptors launched before it skipped would have not chance of interception as the difference in trajectory would be enormous...


Separate buses for each warhead should allow very high precision reducing the need for very powerful warheads too.

Can someone fill me in on what a bus actually entails?

Is it just a bridge/interface that can seperate from the main platform and thus together with its warhead come back down from orbit and towards a target?

Does it have its own thrusters or deployable wings?

The bus has changed over the years from different models.

The first missiles just had one warhead so there was no need for a bus.

The MRV option where multiple warheads were fitted to one missile but no separate guidance was used was deployed simply because in terms of hitting hard targets like a tank armour the biggest heaviest penetrator is best, but when the target is soft like a city then one big warhead is not efficient... all the energy is concentrated in one area so you don't cover a wide area as efficiently. A cluster munition design where several warheads spread out just before impact spreads the destruction far more efficiently.

The idea is to have a bus, or a simple platform that all your warheads sit on in the nose of the missile so that a minute or two before impact the warheads are released to fall separately to spread the impact points fairly evenly around the point of aim of the missile to spread the destruction.

4 100Kt warheads spread around the target area can do rather more damage to soft targets like cities than a single very powerful warhead... just like 200 x 2.5kg HE Frag munitions will kill people out in the open more efficiently than a single 1,00kg bomb even though the HE weight is double for the single bomb it overkills in the centre and lacks fragmentation range to get the the spread out targets the mine-lets can kill or injure.

In that case the bus does not manouver, it just holds the warheads together in a package until it is a fixed distance from impact and then releases the warheads.

In the case of the MIRV bus the bus actively manouvers between releasing warheads like a bomber manouvers to release a bomb to each target it is attacking.

Obviously each target must be on its flight path or near to it, but the bus needs to know where it is in space and where its targets are and to be able to manouver to release the warheads on optimal flight paths to hit the targets.... the warheads generally just fall and have no propulsion or guidance of their own.

MaRV warheads have guidance and manouver capability for the warheads which achieves much better terminal precision and the ability to make themselves a difficult target for ABM system as they don't fly a predictable flight path (ie not ballistic).

According to the source, the check was meant to drill combat operations planning skills and control of army groups "in conditions of control centers’ movements in unfamiliar territories." "A snap combat readiness check was conducted in the Central and Eastern military district for four days, from March 20," the source said. However he did not say how many servicemen had taken part in the check.

According to the source, the check was meant to drill combat operations planning skills and control of army groups "in conditions of control centers’ movements in unfamiliar territories."

Over 10,000 troops will be involved in the maneuvers of three missile armies of Russia’s Strategic Missile Force, the Defense Ministry of Russia announced on Tuesday.

"Command and staff exercises will be held in March in formations of the Vladimir, Orenburg and Omsk missile armies.

That's the idea. They can maneuver in space (and potentially in atmosphere) . Thaads and SM3 can be rendered ineffective. I wonder if thsi also can add some range to ballistic missile.

First regiment of Kozelsk missile division rearmed with Yars missiles — source

The Kozelsk missile division is the first in Russia’s strategic missile force to be rearmed with the new silo-based missile Yars

MOSCOW, November 29. /TASS/. The first regiment of the Kozelsk missile division of Russia’s strategic missile force has been rearmed with silo-based missiles Yars and will enter combat duty next week, a source at the Defense Ministry has told TASS.

"The first regiment of the Kozelsk missile division (stationed in the Kaluga region), has been rearmed with the silo-based missiles Yars. The regiment will enter combat duty next week," the source said.

The Kozelsk missile division is the first in Russia’s strategic missile force to be rearmed with the new silo-based missile Yars. The Defense Ministry said earlier this division will receive ballistic missiles Yars and put them into the silos by the end of 2018. Since 1982 this division has used the UR-100NU missiles

Earlier, strategic missile force commander Sergei Karakayev said the Yars missiles will be delivered to four missile regiments in the Kozelsk, Yoshkar-Ola, Novosibirsk and Irkutsk divisions.

Russian MOD says first silo-based Yars ICBM regiment to go on combat duty at Kozelsk (28th Msl Div) this week.

https://t.co/aZVBZ9W6po

well after Yars has new maneuvering blocks no wonder that is happily installed in siloes

First silo-based Yars regiment in Kozelsk is fully operational

According to the ministry of defense, "the first regiment of Yars missiles in Kozelsk began combat duty." Which is interesting, since the military reported that the regiment was on combat duty in December 2015 (here is a link to the Interfax story).

What probably happened was that in 2015 the regiment began combat duty with six missiles and is brought to full ten only now. I was too optimistic in suggesting that the 2015 missile delivery plan meant that six silo-based Yars will be deployed in Kozelsk that year. Rather, it was the "normal" rate - two missiles a year. Still, if that was the case, the deployment should have been completed in 2017 - apparently there was another delay, besides production of missiles.

Now that the fist regiment is fully ready, one would expect to see more activity at silos of the second regiment.
