Based on some fragmentary information published about this missile, I would like to propose the following hypothesis on this missile.
1- The missile is an ICBM.
2- It uses stages derived from the first two stages of Yars, topped by a number of hypersonic scramjet-powered independently-targeted reentry vehicles.
3- This arrangement would give it a maximum range of well over 11,000 km, which represents a performance level considered important, for an ICBM, by the Russians.
4- If the reentry vehicles proposed under item “2” were replaced with heavy, unpowered reentry vehicles, the range of the missile will fall to around 6,000 km, which is consistent with some of the discussions that surround this missile.
5- Due to the above considerations the missile system would have a mass that is substantially lower than that of Yars missile system—missile + launcher mass of 80 tonnes.
6- The missile’s road-mobile launcher would also be substantially smaller and lighter than that of the Yars missile system, i.e. it would be in the MZKT-79291 class.
