MOSCOW, April 10 (RIA Novosti) - The RS-20V Voyevoda-M (SS-18 Satan) intercontinental ballistic missile, introduced almost 21 years ago, will remain in service until 2019, the commander of Russia's Strategic Missile Forces (SMF) said on Friday.

"The extension in the service life of the [Voyevoda-M] missile will allow us to keep these missiles, the most powerful in the world, in the SMF for another eight-10 years," Col. Gen. Nikolai Solovtsov said.

"We have no technical difficulties in accomplishing this task," he added.

The general also said Russia was developing a new ICBM comparable to the SS-18, and would gradually decommission older versions of the missile "in order to ensure nuclear safety."

According to publicly available sources, Russia currently has 88 SS-18 missile silo launchers, most of them deployed at the Dombarovsky missile base in the Orenburg Region, southern Urals.

The missile is armed with a warhead fitting 10 multiple independently targetable re-entry vehicles (MIRVs) with a yield of 550 to 750 kilotons each.

It has a maximum range of 11,000 km (6,800 miles) with a launch mass of over 210 tons and a payload of 8.8 tons.

They certainly like to go with unusual. (2nd and 3rd stage nozzles look folded almost forward for compactness.)

There has been talk about an SS-18 successor, in my brief memory, since at least the mid-80s (totally new and not new model) Jane's originally called it the SS-X-26. The information they had was that it was to be the same dimensions but with solid fuel and apparently a larger payload - 10 to 12 tons.

This picture seems to fit that description because in order for it to have more propellant for the same height it was to have, in Jane's description, "nested rocket stages" This type of engine configuration was being studied in the US as well as "conformal rocket nozzles". The idea was similar to the MX's 2nd stage but with no requirement for complex mechanics to extend the nozzle as it would not extend.

If you Google RS-24 and click on the Globalsecurity.org link they have some interesting information and I think some diagrams, although I don't believe we are talking the same missile as this diamgram.

Satan replacement it's not a myth
and it's not RS-24 Yars (which is, simplyfying, just multi-MIRV Topol-M)

comments on CAD drawing from an expert:

- missile stages comparative size is nonsense
- such stages' cutoff engines is a relict of first ICBMs, especially in regards to first stage
- national insignia spreaded here and there like lights on Xmas tree? way too much for original-sourced CAD drawing
- drawing made in Kompas CAD, tool often used by Bauman MSTU students.

Resume - may be another student project. But seems not even undergraduate.

Flateric - For comparison I have attached a "nominal ICBM" picture from Aerospace Corporation's Crosslink Magazine. With regard to stage sizing the differences are apparent

Yes, the relative size of the stages is a bit strange. Whatever the origin of this CAD image is, it's important to note that Russia seems not (thus far) commited to building a new heavy ICBM - it has been studied for a long time and the industry is pushing hard, but no formal decision yet.
