Polish military divers neutralise one of WWII's largest bombs
The detonation on Tuesday concluded the operation to remove the dangerous 5.4-tonne Tallboy bomb at the bottom of a channel in Świnoujście, a Baltic port city in the far northwest of Poland. There were no immediate reports of injuries.
Lieutenant Commander Grzegorz Lewandowski a spokesman for the Polish Navy's 8th Coastal Defence Flotilla based in Świnoujście, said the bomb had been neutralised and would not pose any more threats. He added that all of the military divers were outside the danger zone.
According to witnesses, the explosion was briefly felt near the island of Karsibor. However, there were no immediate reports of injuries or damage to infrastructure.
The five-tonne device, nicknamed 'Tallboy' and also known as an 'earthquake bomb,' was dropped by the Royal Air Force in an attack on a Nazi warship in 1945. It was discovered last year during dredging close to the port city of Świnoujście. The bombs were designed to explode underground next to a target, triggering shock waves that would cause destruction. Until the unexploded bomb was found, it was believed that all such devices dropped on the German ship had exploded.
The Tallboy bomb discovered in Świnoujście had a length of 6.44 metres and weighed 5.4 tonnes. It contained 2.4 tonnes of explosives, equivalent to approximately 3.6 tonnes of TNT.
Preparations for the neutralisation of the bomb, referred to as the largest of its kind in Europe and possibly also in the world, lasted from September last year. In addition, it was necessary, among other precautions, to establish a security zone in the area and suspend all traffic in the port during the high-risk operation.
