Tactical nuclear weapon in the context of "Artillery shell"

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 the smallest nuclear weapon in both weight and yield to have entered US service. It was a compact implosion device containing plutonium-239 as its fissile material, and in its various versions and mods it had a yield of 10 to 1,000 tons of TNT (42 to 4,184 gigajoules).

The weapon had two distinct versions: a warhead used in the AIM-26 Falcon air-to-air missile and in the Davy Crockett recoilless gun, and another used in the Special Atomic Demolition Munition (SADM) system, along with several mods for each version. The two types are distinct in that much of the design between them was different, to the point that during the development of the SADM it was proposed that it be given its own unique mark designation.

The SEPECAT Jaguar is a British-French supersonic jet attack aircraft originally used by the British Royal Air Force and the French Air Force in the close air support and nuclear strike role. As of 2025, the Jaguar remains in service with the Indian Air Force.

Originally conceived in the 1960s as a jet trainer with a light ground attack capability, the requirement for the aircraft changed to include supersonic performance, reconnaissance and tactical nuclear strike roles. The aircraft were manufactured by SEPECAT (Société Européenne de Production de l'avion Ecole de Combat et d'Appui Tactique), a joint venture between Breguet and the British Aircraft Corporation, one of the first major joint British-French military aircraft programmes. It was also later license produced by Hindustan Aeronautics Limited in India for use of the Indian Air Force. Various single and two–seater variants of the aircraft have been developed over the years, including a maritime strike version. A carrier-based variant was also planned for French Navy service, but this was cancelled in favour of the cheaper, fully French-built Dassault-Breguet Super Étendard.

A shell, in a modern military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. A shell can hold a tracer.

All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called grenades, derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with grenade are still used for an artillery or mortar projectile in some European languages.

The M28 or M29 Davy Crockett Weapon System was a tactical nuclear recoilless smoothbore gun for firing the M388 nuclear projectile, armed with the W54 nuclear warhead, that was deployed by the United States during the Cold War. It was the first project assigned to the United States Army Weapon Command in Rock Island, Illinois. It remains one of the smallest nuclear weapon systems ever built, incorporating a warhead with yields of 10 to 20 tons of TNT (42 to 84 GJ). It is named after American folk hero, soldier, and congressman Davy Crockett.

The Strategic Forces Command (SFC), forms part of India's Nuclear Command Authority (NCA). It is responsible for the management and administration of the country's tactical and strategic nuclear weapons stockpile. It was created on 4 January 2003 by the Atal Bihari Vajpayee Government. Air Marshal Teja Mohan Asthana became its first commander-in-chief. The previous commander-in-chief was Vice Admiral Suraj Berry who took over in October 2023. The current chief is Lt Gen Dinesh Singh Rana.

A strategic nuclear weapon (SNW) is a nuclear weapon that is designed to be used on targets often in settled territory far from the battlefield as part of a strategic plan, such as military bases, military command centers, arms industries, transportation, economic, and energy infrastructure, and countervalue targets such areas such as cities and towns. It is in contrast to a tactical nuclear weapon, which is designed for use in battle as part of an attack with and often near friendly conventional forces, possibly on contested friendly territory. As of 2025, strategic nuclear weapons have been used twice in the 1945 United States bombings of Hiroshima and Nagasaki.
