Coronados served as a major component in the Naval Air Transport Service (NATS) during World War II in the Pacific theater. Most had originally been acquired as combat patrol aircraft, but the limitations noted above quickly relegated them to transport service in the American naval air fleet also. By the end of World War II, the Coronado was outmoded as both a bomber and a transport, and virtually all of them were quickly scrapped by the summer of 1946, being melted down to aluminum ingots and sold as metal scrap, or used as targets for fighter gunnery practice.
