What is the highest yield nuclear weapon in the US arsenal?

B83
The B83 is a variable-yield thermonuclear gravity bomb developed by the United States in the late 1970s and entered service in 1983. With a maximum yield of 1.2 megatons (5.0 PJ), it is the most powerful nuclear weapon in the United States nuclear arsenal. It was designed by Lawrence Livermore National Laboratory.

What was the yield of the bombs in Fallout?

An average strategic warhead in 2077 had a yield of about 200-750 kilotons, but with a massive increase in radioactive fallout in place of thermal shock.

What was the yield of the first hydrogen bomb?

10.4 megatons
It was successfully detonated during Operation Ivy, on November 1, 1952, at Enewetak. The explosion achieved a yield of 10.4 megatons (million tons), 500 times larger than the Nagasaki bomb, and it produced a crater 1,900 metres (6,240 feet) in diameter and 50 metres (164 feet) deep.

What was the yield of the Hiroshima and Nagasaki nuclear bombs?

activation data give a yield of about 15 kt. Hiroshima and 10 percent for Nagasaki.

Which is the highest yield nuclear weapon ever made?

Only five produced. (5 Megatons) TX/ Mark 16 – First weaponized thermonuclear weapon ( Ivy Mike device). Only cryogenic weapon ever deployed. Only five produced. (6–8 Megatons) Mark 17 – High-yield thermonuclear. Heaviest U.S. weapon, second highest yield of any U.S. weapon. Very similar to Mk-24. (10–15 Megatons)

What was the name of the nuclear bomb used in Nagasaki?

Mark 3 – ” Fat Man ” plutonium implosion weapon (used against Nagasaki), effectively the same as the “Gadget” device used in the Trinity (nuclear test) with minor design differences. (21 kilotons, 1945–1950) Mark 4 – Post-war “Fat Man” redesign. Bomb designed with weapon characteristics as the foremost criteria. (1949–1953)

What was the name of the Manhattan Project plutonium bomb?

Implosion Mark 2 – Another Manhattan Project plutonium implosion weapon, a hollow pit implosion design, was also sometimes referred to as Mark 2. Also cancelled 1944.

What was the name of the first Soviet nuclear bomb?

The RDS-2 was an entirely Russian design, delayed by development of the RDS-1 RDS-3, 42 kiloton bomb. First Soviet bomb tested in an airdrop on 18 October 1951. First ‘mass-produced” Soviet bomb RDS-3I, 62 kiloton bomb. Tested 24 October 1954. The RDS-31 was an improved RDS-3 with external neutron generator RDS-4, “Tatyana” 42 kiloton bomb.
