Apparently (according to Artjohm and others) it was the Avangard ICBM, more or less a replacement for the UR-100.
Russia tests secret missile after Nato shield launched
http://www.bbc.co.uk/news/world-europe-18172726A new intercontinental ballistic missile (ICBM) so secret it has no name yet has been successfully tested in Russia, the defence ministry says. The new weapon is designed to penetrate Nato's European missile defence shield, Russian defence sources told the Interfax news agency. The test came days after Nato said its system had reached "interim operational capability".
The missile carried a dummy warhead and was fired 6,000km (3,730 miles).
Apparently (according to Artjohm and others) it was the Avangard ICBM, more or less a replacement for the UR-100.
Not that secret though, if they made news about it![]()
So it has manoeuvrable re-entry vehicles that can escape interception ?
They had them with topol-M if not mistaken.
Arty had this to say about the missile.
It's Avangard, a new ICBM. It used Topol-M first stage and more energetic fuels for shorter boost phase. And, possibly, a new bus-less multiple warhead stage (MITT has been advertising this new thing for some time).
It's the same missile that failed last September.
Kommersant made a claim today based on sources in the military that the new missile is a land-based version of Bulava.
Kommersant is generally reliable, take this with a condiment of your choice. Previously, Kommersant and Vedomosti said it used a Topol-M stage (as I mentioned before).
They also claimed it is designed for 10 warheads (Bulava has 6), which implies a pretty significant modification to the original SLBM. This is the part where I start doubting these "sources".
UR-100N has a 4 times heavier payload than Bulava. Putting 10 warheads on the existing Bulava (with no modifications) would shrink the weight of each RV from approximately 90-100 kg to around 50-60 kg, which is extremely small for an ICBM.
More likely is that UR-100N is goIng to be replaced by a silo-based Makeyev/NPO Mash 4-ton payload liquid missile, while this new thing is a future replacement for the Topol-M/Yars mobile solid ICBMs.
About "Avangard" http://militaryrussia.ru/blog/topic-553.html
I am a bit puzzled why UR-100N and not SS-N-20? Or even better variant: why not Trident I?
Anyway RIA claims (i.e. here http://ria.ru/spravka/20111227/527639138.html) Bulava can have 10 warheads. Do they lie too?
I would rather expect that this "unknown official" just said "it's land based Bulava" with stressing attention on "new fuel" thing (see "nano technologies" meme) and everything else being added by journalist later during writing. "Normal thing".
In any case congratulations to the engineers that actualized this accomplishment.
It is only an intelligible supposition that most of the technical specifications would remain confidential to the public.
