Russia has begun mass production of mobile bomb shelters that can protect against a variety of man-made threats and natural disasters including radiation and shockwaves, the emergency ministry’s research institute said.

The “KUB-M” shelter looks like a reinforced shipping container. It can give some protection against radiation, shrapnel, debris and fires and can be deployed in Russia’s vast northern permafrost, according to the state institute.

The standard unit accommodates 54 people but additional modules can be added, the institute said.
