The initial three-stage design of Tsar Bomba was capable of yielding approximately 100 Mt (approximately 3,000 times the power of the Hiroshima (15 kt) and Nagasaki (21 kt) bombs, combined); [39] however, it was thought that this would have resulted in too much nuclear fallout, and the aircraft delivering the bomb would not have had enough time ...
Log–log plot comparing the yield (in kilotonnes) and mass (in kilograms) of various nuclear weapons developed by the United States.. The explosive yield of a nuclear weapon is the amount of energy released such as blast, thermal, and nuclear radiation, when that particular nuclear weapon is detonated, usually expressed as a TNT equivalent (the standardized equivalent mass of trinitrotoluene ...
Megatons of TNT Watt-hours [Wh] 1 × 10 −12: 1.162 Wh ≈ 1 food calorie (large calorie, kcal), which is the approximate amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius at a pressure of one atmosphere. 1 × 10 −9: 1.162 kWh
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 ...
This U.S. design was the heavy but highly efficient (i.e., nuclear weapon yield per unit bomb weight) 25 Mt (100 PJ) B41 nuclear bomb. [21] The Soviet Union is thought to have used multiple stages (including more than one tertiary fusion stage) in their 50 Mt (210 PJ) (100 Mt (420 PJ) in intended use) Tsar Bomba.
Comparing this to the volumes of other large thermonuclear bombs, the 1961 Soviet-era Tsar Bomba itself measured 8 metres (26 ft) long by 2.1 metres (6 ft 11 in) in diameter, indicating that the yield is at least several tens of megatons, generally consistent with early reports of 100 megatons.

The project initially envisioned the use of four 100 kiloton devices to excavate a channel, and two one-megaton devices to excavate a turning basin, for a total of 2.4 megatons of explosive equivalent, displacing 70,000,000 short tons (64,000,000 t) of earth.
