The components of a B83 nuclear bomb used by the United States. This is a list of nuclear weapons listed according to country of origin, and then by type within the states. . The United States, Russia, China and India are known to possess a nuclear triad, being capable to deliver nuclear weapons by land, sea and
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.
Some nuclear weapons are designed for special purposes; most of these are for non-strategic (decisively war-winning) purposes and are referred to as tactical nuclear weapons. The neutron bomb purportedly conceived by Sam Cohen is a thermonuclear weapon that yields a relatively small explosion but a relatively large amount of neutron radiation .
Topol-M launch from silo. A missile launch facility, also known as an underground missile silo, launch facility (LF), or nuclear silo, is a vertical cylindrical structure constructed underground, for the storage and launching of intercontinental ballistic missiles (ICBMs), intermediate-range ballistic missiles (IRBMs), medium-range ballistic missiles (MRBMs).
A B83 casing. The B83 is a variable-yield thermonuclear gravity bomb developed by the United States in the late 1970s that entered service in 1983. With a maximum yield of 1.2 megatonnes of TNT (5.0 PJ), it has been the most powerful nuclear weapon in the United States nuclear arsenal since October 25, 2011 after retirement of the B53. [1]
The M65 atomic cannon, often called Atomic Annie, [6]: 92 was an artillery piece built by the United States and capable of firing a nuclear device. It was developed in the early 1950s, at the beginning of the Cold War; and fielded between April 1955 and December 1962, in West Germany, South Korea and on Okinawa.
W80 Mod 1 warhead W80 Mod 4 warhead for the LRSO program.. The W80 is a low to intermediate yield two-stage thermonuclear warhead deployed by the U.S. enduring stockpile with a variable yield ("dial-a-yield") of 5 or 150 kilotonnes of TNT (21 or 628 TJ).
Tactical nuclear weapons were a large part of the peak nuclear weapons stockpile levels during the Cold War. US scientists with a full-scale cut-away model of the W48 , a very small tactical nuclear weapon with an explosive yield equivalent to 72 tons of TNT (0.072 kiloton).
