TNT equivalent is a convention for expressing energy, typically used to describe the energy released in an explosion.The ton of TNT is a unit of energy defined by convention to be 4.184 gigajoules (1 gigacalorie), [1] which is the approximate energy released in the detonation of a metric ton (1,000 kilograms) of TNT.
Comparative fireball radii for a selection of nuclear weapons. [citation needed] Contrary to the image, which may depict the initial fireball radius, the maximum average fireball radius of Castle Bravo, a 15-megatonne yield surface burst, is 3.3 to 3.7 km (2.1 to 2.3 mi), [6] [7] and not the 1.42 km displayed in the image.
The Mark 39 design was a thermonuclear bomb and had a yield of 3.8 megatons. [1] It weighed 6,500–6,750 pounds (2,950–3,060 kilograms), [2] and was about 11 feet, 8 inches long (3.556 meters) [2] with a diameter of 35 inches (89 cm). [2] The design is an improved Mark 15 nuclear bomb design (the TX-15-X3 design and Mark 39 Mod 0 were the ...

Operation Redwing was a United States series of 17 nuclear test detonations from May to July 1956. They were conducted at Bikini and Enewetak atolls by Joint Task Force 7 (JTF7). [1]
The crew's final view of the aircraft was in an intact state with its payload of two Mark 39 thermonuclear bombs still on board, each with yields of 3.8 megatons. [b] Sometime between the crew ejecting and the aircraft crashing, the two bombs separated from the aircraft. [7] The pilotless aircraft broke up in the air shortly after the crew ejected.
Gun-type (8–30 kilotons). Mark 12 – Light-weight bomb to be carried by fighter aircraft (12–14 kilotons). Mark 13 – Improved version of Mk-6 (cancelled August 1954). TX/Mark 14 – First deployable solid-fuel thermonuclear bomb (Castle Union device). Only five produced. (5 Megatons) Mark 15 – First "lightweight" thermonuclear weapon ...
