I was recently reading a very interesting article published by various sources on the history of the R-36 (SS-18) Satan missile and ran across something very odd. There is brief mention of authorization to construct a hundred megaton version of the RDS-250 built into an RV,but like the work done by the 15th directorate on Biological and Chemical RVs the record goes cold after 1962. I would be inclined to believe it was a Soviet Misinformation program to scare the DoD, however there was a mod put out for the R-36 that carried a twenty megaton RV for the destruction of western intelligence satellite patterns, so it is within logic. consider also the secrecy surrounding Soviet RVs, especially high yield versions and the experience they had with putting large weapons into orbit. Also consider the soviet obsession with single high yield missles over MIRV versions. Another curious thing i found was in the demonstrater video for the brand new RS-24, the missile is seen in its 3rd stage with a single large "100 megaton" warhead attached. this video was most definately professionaly doneand the Russian ministry of defense has been anything but forthcoming with information regarding its warheads(aside from making it a clear point to state it is Fusion based). Its a shot in the dark but i was wondering if someone out there could shed a little more light on this, perhaps a cancellation date or a test of an abnormally large RV somewhere in Soviet archives. it would be greatly appriciated.
