The two superpowers, the Soviet Union and the United States of America, chose different structures for their nuclear arsenals. Washington gave preference to ballistic missile submarines as the basis of the US Strategic Nuclear Forces. Moreover, the West managed to cover the global ocean with acoustic stations that tracked the movement of Soviet subs.
In 1987, the USSR decided to place its missiles on railways, taking the advantage of its giant and multipath railroad network, in which a train could hide from satellite reconnaissance. Each of the 12 Soviet ‘nuke trains' was armed with three RT-23 Molodets (SS-24 Scalpel) intercontinental ballistic missiles (ICBMs) carrying 10 warheads. The trains looked like refrigerator cars from the space.
The new "nuke train" is similar to a nuclear-capable submarine in its function. The cars are so hard that they can resist an explosion of a nuclear warhead just several hundred meters away. A train can run for a month autonomously and pass up to 1,000 kilometers daily.
The trains will be protected with a cutting-edge stealth technology, electronic warfare systems and counterterrorism measures.
Five "Barguzin" regiments are expected to enter Russia's SMF by 2020.
