What is the oldest US Navy commissioned vessel?

The USS Constitution is the oldest commissioned vessel in the United States Navy, often referred to as "Old Ironsides." Launched in 1797, it serves as a symbol of American naval history and resilience. The ship has played a prominent role in various conflicts, including the War of 1812, where it famously defeated several British ships. Today, it remains commissioned and is preserved as a museum ship in Boston, Massachusetts, allowing visitors to learn about its storied past and the early years of the U.S. Navy.

In contrast, while other vessels listed have their own historical significance, they do not possess the same age or context. The USS Nimitz, for example, is a modern aircraft carrier commissioned in the 1970s, and the USS Enterprise and USS Missouri, although notable ships, were commissioned in the 20th century. Understanding the distinction between these ships highlights the unique legacy held by the USS Constitution within the Navy's heritage.
