The USS Oahu was a U.S. Navy escort airplane carrier built and launched during the Second Great War from the East Coast of the United States. In 1944 the Oahu and her sister ship, the Irish Sea, were part of a task force belonging to the US Atlantic Fleet which was tasked with hunting English convoy ships travelling between the United Kingdom and Argentina. The carrier contained only fighters and dive bombers, not torpedo bombers. This was because the brass believed that they would be sitting ducks, while the dive bombers could do a better job.
