Russia has launched mass production of mobile shelters called ‘KUB-M’ that can protect against various man-made threats and natural disasters, including radiation and blasts. Each unit can house 54 people and operates independently for 48 hours. This development coincides with escalating tensions in the Ukraine conflict, as the U.S. has authorized Ukraine to launch long-range missiles into Russia, prompting warnings from the Kremlin about potential repercussions.
