At over ten tons, the Grand Slam is the heaviest aerial bomb used in a war to date. The explosive bomb filled with conventional explosives was developed in late 1944 and used by the British Air Force during World War II against large targets such as heavily armored bunkers and bridges.

Since this weapon system was not available until the end of the war, it was only used 41 times, mainly against bridges and viaducts. Its effect was devastating in each individual case: Within a radius of about one hundred meters there was practically no chance of survival. The pressure wave of the explosion caused earthquake-like vibrations when detonating under the surface of the earth, which also caused larger buildings in the vicinity to collapse.

On April 9, 1945, No. 617 Squadron attacked the submarine bunker Fink II in Hamburg with Tallboys and Grand Slams and scored several hits.
