Shell (projectile)
A shell is a type of projectile used in weapons. It is filled with explosive or other things such as an incendiary device. It is similar to a bomb but is made to be shot out of a gun. Shells are usually large caliber projectiles fired by artillery, armored vehicles (including tanks), and warships. A fuze detonates the explosive or releases whatever else the shell may be carrying.
Anti-tank guns fire thick shells without much explosive inside. Shells usually have the shape of a cylinder but taper towards the front end to form a point. However, special shells may use other shapes.

US scientists with a full-scale cut-away model of the W48 155 millimeter nuclear artillery shell, a very small tactical nuclear weapon with an explosive yield equivalent to 72 tons of TNT (0.072 kiloton). It could be fired from any standard 155 mm (6.1 inch) howitzer (e.g., the M114 or M198).
