Determining the power of explosions is difficult, but this was probably the largest planned explosion in history until the 1945 Trinity atomic weapon test, and the largest non-nuclear planned explosion until the 1947 British Heligoland detonation (below). The Messines mines detonation killed more people than any other non-nuclear deliberate ...
The M-388, a W54 nuclear warhead variant, weighed less than 60 pounds (27 kg). At the projectile's lowest yield setting of 10 tons, roughly equivalent to a single MOAB, its explosive force was only 1/144,000th (0.0007%) that of the Air Force's 1.44-megaton W49 warhead, a nuclear weapon commonly found on American ICBMs from the early 1960s.
The Halifax Explosion was one of the largest artificial non-nuclear explosions. An extensive comparison of 130 major explosions by Halifax historian Jay White in 1994 concluded that it "remains unchallenged in overall magnitude as long as five criteria are considered together: number of casualties, force of blast, radius of devastation ...
While the 21,600-pound (9,797-kg) GBU-43 is billed as the U.S. military's most powerful non-nuclear bomb, its destructive power, equivalent to 11 tonnes of TNT, pales in comparison with the ...
The explosion used 7400 tons (6700 metric tons) of surplus World War II ammunition, which was placed in various locations around the island and detonated at 1 p.m. on 18 April 1947 by the Royal Navy. The energy released was 1.3×10 13 J, or about 3.2 kilotons of TNT equivalent [1] making it the largest artificial non-nuclear explosion at
The 1947 Texas City disaster was an industrial accident that occurred on April 16, 1947, in the port of Texas City, Texas, United States, located in Galveston Bay.It was the deadliest industrial accident in U.S. history and one of history's largest non-nuclear explosions.
STORY: The blast on Aug 4, 2020 killed at least 220 people. One of the largest non-nuclear explosions in history, it was caused by massive stores of ammonium nitrate kept at the site and neglected ...
Robert Hewson, an editor for Jane's Information Group, told the BBC it was likely that FOAB indeed represented the world's biggest non-nuclear bomb. "You can argue about the numbers and how you scale this but the Russians have a long and proven history of developing weapons in the thermobaric class", he says.
