3. n. An explosive projectile, consisting of a hollow ball or spherical shell, generally of cast-iron, filled with a bursting charge, fired from a mortar, and usually exploded by means of a fuse or tube filled with a slow-burning compound, which is ignited by the exploding powder when the mortar is discharged. Bombs may be thrown in such a direction as to fall into a fort, a city, or an enemy's camp, where they burst with great violence, and often with terrible effect. The length and composition of the fuse must be calculated in such a way that the bomb shall burst the moment it arrives at the destined place. Bombs are now commonly termed shells, though shell in the sense of a projectile has a wider meaning. See shell. Also called bombshell.
