Tactical Nuclear Weapon - Types

Types

Tactical weapons include not only gravity bombs and short-range missiles, but also artillery shells, land mines, depth charges, and torpedoes for anti-submarine warfare. Also in this category are nuclear armed ground-based or shipborne surface-to-air missiles (SAMs) and air-to-air missiles.

Small, two-man portable, or truck-portable, tactical weapons (sometimes misleadingly referred to as suitcase nukes), such as the Special Atomic Demolition Munition and the Davy Crockett recoilless rifle, have been developed, although the difficulty of combining sufficient yield with portability could limit their military utility. In wartime, such explosives could be used for demolishing "choke-points" to enemy offensives, such as at tunnels, narrow mountain passes, and long viaducts. Twenty nuclear torpedo sea mines were alleged by the International Atomic Energy Agency to have been laid on 10 January 1970 by a Soviet November class attack submarine in the Bay of Naples to, in a time of war, destroy or deny access to the US Seventh Fleet. They are believed to still be on the seabed.

Other new tactical weapons undergoing research include earth penetrating weapons which are designed to target enemy-held caves or deep-underground bunkers.

There is no precise definition of the "tactical" category, neither considering range nor yield of the nuclear weapon. 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 of kilotons, or potentially hundreds, several times that of the weapons used in the atomic bombings of Hiroshima and Nagasaki.

Some tactical nuclear weapons have specific features meant to enhance their battlefield characteristics, such as variable yield which allow their explosive power to be varied over a wide range for different situations, or enhanced radiation weapons (the so-called "neutron bombs") which are meant to maximize ionizing radiation exposure while minimizing blast effects.
