Worlds biggest bomb

The WWII Grand Slam earthquake bombs made and used by the British to attack U-Boat pens and other concrete targets was the largest bomb used in that era. The 22000 pound (10000 kilogram) bomb - containing 9135 pounds of Torpex explosive with a yield of 6.2 tons of TNT equivalent - was carried by specially modified Avro Lancaster bombers.

The Aviation Thermobaric Bomb of Increased Power, ATBIP, nicknamed the 'Father of all Bombs', is likely the largest non-nuclear bomb ever created with a yield of 44 tons of TNT equivalent. It carries just over 7 tonnes of enhanced explosive which uses atmospheric oxygen to burn - hence the thermobaric description - which makes it more powerful but equally as difficult to control.

The Cold War-era RDS-220, commonly known as Tsar Bomba (the Tsar Bomb) is the largest bomb of any kind ever built and detonated. Only one was ever made and subsequently detonated in 1961 in Russia, with an estimated yield of over 50 megatons. The fireball was large enough to reach the ground and the altitude of the bomber that carried it, 10.5 kilometres high - it was bright and hot enough to be seen and felt 1000 kilometres away from ground zero. The shockwave was felt even on its third journey around the world, and Windows were smashed in Finland and Sweden (around 800 kilometres away).
