A warhead is the section of a device that contains the explosive agent or toxic (biological, chemical, or nuclear) material that is delivered by a missile, rocket, torpedo, or bomb. Classification [ edit ]
There is no exact definition of the "tactical" category in terms of range or yield of the nuclear weapon. [ 2 ] [ 3 ] The yield of tactical nuclear weapons is generally lower than that of strategic nuclear weapons, but larger ones are still very powerful, and some variable-yield warheads serve in both roles.
George Shultz has said, "If you think of the people who are doing suicide attacks, and people like that get a nuclear weapon, they are almost by definition not deterrable". [61] As of early 2019, more than 90% of world's 13,865 nuclear weapons were owned by Russia and the United States. [62] [63]
The Yearbook published by SIPRI in 2024 revealed that China's nuclear warheads stockpile increased by 90 in 2023, reaching 500 warheads. [67] US Department of Defense officials estimate that the Chinese had more than 600 operational nuclear warheads as of December 2024, and it was on track to posess 1,000 nuclear weapons by the year 2030.

There is no precise definition of the "strategic" category for either range nor yield. [3] [4] The yield of tactical nuclear weapons is generally lower than that of strategic nuclear weapons, but larger ones are still very powerful, and some variable-yield warheads serve in both roles. Modern tactical nuclear warheads have yields up to the tens ...
Warhead designs after 1960 took on the character of model changes, with every new missile getting a new warhead for marketing reasons. The chief substantive change involved packing more fissile uranium-235 into the secondary, as it became available with continued uranium enrichment and the dismantlement of the large high-yield bombs.

Cruise missiles equipped with large tandem-charge warheads can use the first charge to create a hole into which the missile flies before exploding the second charge, creating a similar effect of the delayed gravity bomb. An example of an anti-structure tandem-charge warhead is the BROACH warhead.
