The 1.1"/75 caliber gun was an American anti-aircraft weapon of World War II. The name means that it had a bore diameter of 1.1 inches (28 mm) and barrel length of 75 × 1.1 inches = 82.5 inches (2.1 m), using the "caliber" nomenclature common to large artillery pieces.

It was developed when the U.S. Navy Bureau of Ordnance (BuOrd) decided that the .50 caliber machine gun was not adequate for future AA duties:

During the early part of World War II, they were deployed on most U.S. Navy warships of destroyer and larger size.

Due to teething problems that were never rectified, the gun was very unpopular with its crews. It was replaced with the Bofors 40 mm gun whenever possible, but served until the end of the war on some ships.

The guns were sometimes referred to as "Chicago Pianos."

She has appeared in films such as Kids, Men in Black II, 25th Hour, Sin City, Clerks II, Rent, Death Proof, The Rundown, Eagle Eye, Alexander, Seven Pounds, Percy Jackson and the Olympians: The Lightning Thief, and Unstoppable.

Dawson has cited this part of her history when explaining how she learned that "If you wanted something better, you had to do it yourself."
