As A Measurement
Additionally, the term broadside is a measurement of a vessel's maximum simultaneous firepower which can be delivered upon a single target, because this concentration is usually obtained by firing a broadside. This is calculated by multiplying the shell weight of the ship's main armament shells times the number of barrels that can be brought to bear. If some turrets are incapable of firing to either side of the vessel, only the maximum number of barrels which can fire to one side or the other are counted. For example, the American Iowa-class battleships carry a main armament of nine 16-inch (410 mm) main guns in turrets which can all be trained to a single broadside. Each 16-inch shell weighs 2,700 pounds (1,200 kg), which when multiplied by nine (the total number of barrels in all three turrets) equals a total of 24,300 pounds (11,022 kg). Thus, an Iowa-class battleship has a broadside of 12 short tons (11.0 tonnes), the weight of shells that she can theoretically land on a target in a single firing.

Famous quotes containing the word measurement:
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
