From a high of 70,300 active weapons in 1986, as of 2024 there are approximately 3,880 active nuclear warheads and 12,119 total nuclear warheads in the world. [8] Many of the decommissioned weapons were simply stored or partially dismantled, not destroyed.

In 2024 it was estimated that the United States possessed 1,770 deployed nuclear warheads, 1,938 in reserve, and 1,336 retired and awaiting dismantlement (a total of 5,044). 1,370 strategic warheads were deployed on ballistic missiles, 300 at strategic bomber bases in the United States, and 100 tactical bombs at air bases in Europe.

A nuclear weapon [a] is an explosive device that derives its destructive force from nuclear reactions, either fission (fission or atomic bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter.

2023年3月30日 · Multipurpose warhead: Talos SAM/SSM, XW-30-X1 TADM (Tactical Atomic Demolition Munition) warhead; Talos - 1 yield, 3 mods; TADM - 2 yields stockpiled W-31 Warhead

Of the world’s approximate 12,121 nuclear warheads, roughly 9,585 are in the military stockpiles for use by missiles, aircraft, ships and submarines. The remaining warheads have been retired but are still relatively intact and are awaiting dismantlement).

6 天之前 · A nuclear weapon is a device designed to release energy in an explosive manner as a result of nuclear fission, nuclear fusion, or a combination of the two. Fission weapons are commonly referred to as atomic bombs, and fusion weapons are referred to as thermonuclear bombs or, more commonly, hydrogen bombs.

As of January 2025, we estimate that the US Department of Defense maintained an estimated stockpile of approximately 3,700 nuclear warheads for delivery by ballistic missiles and aircraft. Most of the warheads in the stockpile are not deployed but rather stored for potential upload onto missiles and aircraft as necessary.

Currently, about 13,080 nuclear warheads exist worldwide, with Russia holding the most (6,257) and the U.S. following (5,550), a reduction from Cold War peaks. Nuclear weapons have been used in warfare twice: the U.S. dropped bombs on Hiroshima and Nagasaki in 1945, causing massive destruction and casualties.

According to the March 2023 New START declaration, the United States deploys 1,419 strategic nuclear warheads on 662 strategic delivery systems (intercontinental ballistic missiles, submarine-launched ballistic missiles, and heavy bombers).

Nine countries currently have nuclear weapons: Russia, the United States, China, France, the United Kingdom, Pakistan, India, Israel, and North Korea. These nuclear powers differ a lot in how many nuclear warheads they have. The chart shows that while most have dozens or a few hundred warheads, Russia and the United States have thousands of them.
