Not your usual hand grenade.

 

Authorities in Poland are preparing to neutralize a World War II-era bomb found in the water of the Piastowski Canal in Świnoujście which is located in northwestern Poland.

The bomb was discovered during dredging work in September 2019. It has been identified as a Tall Boy bomb, one of the largest bombs used in WWII, and could only be delivered by an Avro Lancaster bomber.

Divers from the 8th Coastal Defense Flotilla cleared the canal of smaller bombs they found in the area. The larger bomb was left while authorities worked with scientists from the Poznan University to find the safest method to remove it.

Magnet fishing allowed in he Polish canals?

 

Any pictures of it going off?

Pawel Rodzos, the director of the Security and Crisis Management Department of the district office said that the team had determined that deflagration was the proper course of action to remove the bomb. Deflagration is the act of setting off the unexploded ordnance where it is found. He also stated that this will be the largest neutralization of a post-war unexploded bomb in Poland.

The process is set to begin in mid-October. It will take several days as it will require special preparation of the facility.

If they blow up this bomb it will make a big hole, Tallboy was a 12,000lb bomb and there is a large pond in the New Forest which is the remains of a crater from a Tallboy when they missed the target called the 'Submarine Pens', no one seems sure what they actuatally were but they are still there, buried at the end of WW2 as it was considered too expensive to demolish.

Back in 1998, I was told that the lefthand arch of this aqueduct on the Gliwice Canal had been primed with explosives during the war, and nobody knew if they had been removed. It was considered too dangerous to look, as an explosion would close the canal, completed in the late 1930s to bypass an earlier 18th century canal.

That is Ashley Bombing Range. Well worth reading it's history of all the different bombs dropped and techniques that were practiced there.

 

The submarine pens were constructed specifically to test Tallboy and GrandSlam. They were covered over after the war but soil erosion has uncovered the concrete edges now.

Cost £500,000 to build, a considerable sum then, though it wasn't big enough to be a submarine pen, maybe a scaled down version. The test bomb (22,000lb Grand Slam) was dropped from 14,00ft instead of 16,000ft to prevent it going supersonic, which would suggest that it wasn't the intention to destroy the'submarine pen', the Americans were the only ones to score a direct hit but the bomb only caused minor damage.
