What is the nickname commonly associated with the USS Constitution?

The nickname commonly associated with the USS Constitution is "Old Ironsides." This moniker stems from the ship's historical significance and its performance during battles in the early 19th century, particularly during the War of 1812. The name reflects the ship's impressive resilience; it reportedly gained this title after British cannonballs bounced off its thick wooden hull, giving the impression that it was made of iron rather than wood. This nickname has become emblematic of the USS Constitution's storied legacy and its enduring status as one of the oldest commissioned warships afloat in the world, representing not only naval history but also national pride.

The other options, while they may be known by specific groups or contexts, do not have the same historical connection or recognition tied to the USS Constitution. "Old Glory" refers specifically to the American flag, "Iron Horse" was a term often used for steam locomotives, and "Sea Lion" does not have a significant association recognizable in naval history.
