Which ship is designated as CV3?

The designation CV3 corresponds to the USS Saratoga. This aircraft carrier was the third ship in the U.S. Navy to carry the name Saratoga and played a significant role during World War II. Commissioned in 1927, the USS Saratoga was notable for her operational history and design adaptations that enhanced her capabilities as an aircraft carrier.

Understanding the designations of U.S. Navy ships is crucial in naval science, as they denote different classes and types of vessels within the fleet. The USS Saratoga, classified as a "fleet carrier," was among the first large carriers built for the U.S. Navy, which expanded naval aviation capabilities significantly during a pivotal time in history.

While the other ships listed have important histories and designations, they do not correspond to CV3, making the USS Saratoga the correct answer in this context.
