In Other News: "Russia to test new Satan 2 ballistic missile that could obliterate 'area the size of UK or Texas'"

Apparently Satan 1 wasn't up to the job.
From the Daily Mirror:

The weapon could deliver nuclear warheads of 40 megatons - 2,000 times as powerful as the atom bombs dropped on Japan

Russia is set to test its biggest ever nuclear missile which is powerful enough to destroy the whole of the UK, Texas or France with a single strike.

The so-called Satan 2 intercontinental ballistic missile could deliver about a dozen nuclear warheads of 40 megatons - 2,000 times as powerful as the atom bombs dropped on Hiroshima and Nagasaki in 1945. 

President Vladimir Putin's Defence Ministry plans to test two RS-28 Sarmat super nukes at the remote Plesetsk Cosmodrome before the end of the year, it was reported.

The 100-tonne weapons - which could enter service as early as 2019 - will make the bombs dropped on Japan look like “popguns”, experts have said.

Russia claims the missiles can "beat any defences" as it seeks to replace its arsenal of SS-18 Satan weapons....MUCH MORE

The question that comes to mind is: "So no 50 megaton Tsar Bomba then?"

The flash of light from the King of Bombs could be seen 600 miles away, the sound circled the earth three times and the mushroom kept growing until it was 40 miles high. Big boom.
That was October 30, 1961.

The multiple warheads carried on the new missile, though smaller are deadlier and almost add up to the yield equivalent of the Tsar.
