Russia has initiated the mass production of mobile bomb shelters designed to safeguard against a range of threats, including shockwaves and radiation resulting from a nuclear explosion.

According to the emergency ministry’s research institute, the “KUB-M” shelter is capable of providing protection for up to 48 hours against various natural and human-made dangers.

The threats identified include explosions and shrapnel from conventional weaponry, falling debris from structures, hazardous chemicals, and fires.

Resembling a fortified shipping container, the “KUB-M” comprises two modules: one designed to accommodate 54 individuals and a technical block. Additional modules can be incorporated as necessary, as stated by the institute.

While the announcement did not directly associate the initiative with any ongoing crisis, it coincided with the recent decision by U.S. President Joe Biden’s administration to permit Ukraine to launch U.S. long-range missiles into Russian territory—a move that the Kremlin has condemned as reckless and one that would provoke a response from Moscow.

On Tuesday, President Vladimir Putin endorsed a new official doctrine that has lowered Russia’s threshold for the use of nuclear weapons.

The research institute described the mobile shelter as a versatile structure that offers protection against various threats, including both natural disasters and man-made incidents, emphasizing its significance in enhancing citizen safety.

The shelter is easily transportable by truck, can be connected to water supplies, and is suitable for deployment in Russia’s extensive northern permafrost regions.
