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 ...
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.
Thermonuclear bombs can be hundreds or thousands of times stronger than their atomic counterparts. Due to this, thermonuclear bombs' yields are usually expressed in megatons which is about the equivalent of 1,000,000 tons of TNT. In contrast, atomic bombs' yields are typically measured in kilotons, or about 1,000 tons of TNT.
The Trinity test on 16 July 1945, near Socorro, New Mexico, was the first-ever test of a nuclear weapon (yield of around 20 kilotons). The Operation Crossroads series in July 1946, at Bikini Atoll in the Marshall Islands, was the first postwar test series and one of the largest military operations in U.S. history.
The yield varies for a tactical nuclear weapon from a fraction of a kiloton to approximately 50 kilotons. [7] In comparison, a strategic nuclear weapon has a yield from 100 kilotons to over a megaton , with much larger warheads available.
Icecap was scheduled for spring 1993. It had a planned yield of 20 to 150 kilotonnes of TNT (84 to 628 TJ) and was to be fired at 1,557 feet (475 m) below the surface in Area 9. [8] A diagnostics canister exists at the site, [9] weighing 500,000 pounds (230,000 kg). [10]
53-58 torpedo with 10 kilotons RDS-9 warhead; 65-73 torpedo with 20 kilotons; VA-111 Shkval with 150 kilotons; Bombs RDS-1, 22 kiloton bomb. Tested 29 August 1949 as "First Light" (Joe 1). Total of 5 stockpiled; RDS-2, 38 kiloton bomb. Tested 24 September 1951 as "Second Light." The RDS-2 was an entirely Russian design, delayed by development ...
[1] [9] A United States Defense Intelligence Agency report from 1999 projected that both Iran and Iraq would join the nuclear club and have 10-20 nuclear weapons in 2020. [10] However, it is worth pointing out that this report was written before the overthrow of Iraqi dictator Saddam Hussein and before information was released indicating that ...
