USS Iona

The USS Iona refers to at least two ships in the United States Navy:

• USS Iona (1863): A steamer acquired by the Union Navy during the American Civil War. She was used as a dispatch ship and blockade runner chaser, operating primarily in the Gulf of Mexico. Specific details about her design and operational history are somewhat limited compared to larger warships of the period. She was decommissioned and sold after the war.

• It is possible, though less certain, that the name "Iona" was considered or proposed for a vessel at another point in naval history, even if it never resulted in an actual commissioned ship. However, historical records primarily associate the name with the Civil War-era steamer. Further research in official naval archives would be needed to confirm other potential instances of the name's usage or consideration.
