What is the smallest nuclear warhead?
The W54 (also known as the Mark 54 or B54) was a tactical nuclear warhead developed by the United States in the late 1950s. The weapon is notable for being the smallest nuclear weapon in both size and yield to have entered US service.
What is the most powerful nuclear warhead?
Tsar Bomba
Tsar Bomba, (Russian: “King of Bombs”) , byname of RDS-220, also called Big Ivan, Soviet thermonuclear bomb that was detonated in a test over Novaya Zemlya island in the Arctic Ocean on October 30, 1961. The largest nuclear weapon ever set off, it produced the most powerful human-made explosion ever recorded.
What is the most powerful nuclear weapon in the US arsenal?
The 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.

How many kilotons does a W9 Nuke have?
The W9 is only the second gun-type nuclear weapon known to have been detonated; the first was the Little Boy nuclear weapon used in World War II. The W9 artillery shell was test fired once, fired from the “Atomic Annie” M65 Atomic Cannon, in Upshot-Knothole Grable on May 25, 1953 at the NTS. Yield was the expected 15 kilotons.
How many missiles did the W56 warhead use?
The W56 warhead was deployed with 650 Minuteman IB missiles and 450 Minuteman II missiles. Based on information available to the public, the W56 possessed one of the highest efficiencies in a nuclear warhead ever manufactured.
What is the difference between a W59 and a MK-5 warhead?
In terms of identification, the W59 refers to the nuclear warhead manufactured, and the term Mk-5 refers to the reentry vehicle used with that specific warhead. Combined, the warhead and reentry vehicle had a width of 16.3 inches, height of 47.8 inches and weighed 550 pounds.
