Estonia: This mobile bomb shelter can withstand NATO calibre shelling
A brand new Estonian-built mobile bomb shelter, the Sub Safe U1, was seen dug into the sand dunes of Tapa Polygon on Saturday.
The shelters, made from polythene, are around six metres (19.70 feet) long and weigh around two tonnes, and purportedly take less than two hours to assemble. Built by Estonian defence firm Terramil, the units can hold up to 12 people.
The shelters were tested under the supervision of scientists from the University of Tartu, proving able to withstand attacks from a 155mm (6.10 inch) shell – NATO's standard artillery calibre.
