Russia reportedly wants to build this doomsday bomb and hide it on a train
Russia is apparently ready to build two terrifying weapons of war: A 100-ton ballistic missile that can destroy countries and a train that can carry and fire six nuclear missiles, according to Pravda, the Communist Party's outlet in Russia.
The missile and train are "on the level of absolute readiness of the industry for their implementation, should the relevant decision be made to include the projects in the state armament program," Russian Deputy Prime Minister Dmitry Rogozin told Pravda.
The 100-ton RS-28 Sarmat nuclear missile, or "Satan 2" as NATO calls it, reportedly holds 10 warheads and is capable of destroying a country the size of France, Newsweek reported. The Satan 2 is an upgraded version of the RS-36M, which NATO called "Satan" in the 70s.
But its production has been put off since 2014. The Russian Defense Ministry also said last week that it wouldn't test it until late 2017.
The Barguzin trains, on the other hand, will look like passenger trains, be able to travel 1,500 miles a day, and hold up to six 55-ton RS-24 Yars thermonuclear ICBMs. The Barguzin train is also an upgrade of a Soviet design that only carried three nuclear ICBMs.
Russia plans to test an ICBM from the Barguzin train in 2019, The National Interest reported in March.
The US considered putting nukes on trains in the 1980s, but later scrapped the idea. Nuclear trains are beneficial in that they're mobile and difficult to locate.
However, a 2014 RAND study said that there are shortcomings to nuclear trains. Railways can be blocked by snow, and the enemy simply has to surveil the railways to find the trains. Also, once found, they're easier to take out.
"Mobile systems that depend on roads or rail lines visible via overhead imagery effectively shrink the target area and could significantly lower the number of missiles required to barrage mobile systems," RAND said.
Russia currently has about 7,000 nuclear weapons, while the US has about 6,800.
