The WWII „Tallboy” bomb exploded underwater being defused in Poland


The biggest World War Two 5.4 ton bomb found in Poland in the Piast Canal which connects the Baltic Sea with the Oder River , dubbed the “earthquake” bomb or Tallboy, exploded under water being defused, on Tuesday. Naval forces used a remote-controlled device to try to “deflagrate” the bomb – a technique that if successful burns the explosive charge without causing a detonation. The shock of the detonation was felt in parts of the city. On Monday, 751 people had to be evacuated from the area before the operation began.


“The deflagration process turned into detonation. The object can be considered as neutralized, it will not pose any more threat,” Second-Lieutenant Grzegorz Lewandowski, the spokesman of the 8th Coastal Defense Flotilla, was quoted as saying by state-run news agency PAP. All divers participating at the defusing operation were outside the danger zone. No one was injured. No infrastructure has been damaged in Swinoujscie. The Tallboy bomb was designed by British aeronautical engineer Barnes Wallis and was used by the Royal Air Force to destroy large Nazi-controlled objects. Unexploded wartime bombs, missiles and grenades are still often found in the country.
