The escort carrier USS Bogue (CVE-9) was specifically designed to locate and destroy German U-boats during the Battle of the Atlantic. It proved to be the most successful carrier in Anti-Submarine Warfare (ASW) during World War II. This book provides a comprehensive account of the Bogue's construction and commissioning, as well as the deployment of Naval Aviation composite squadrons that carried out missions from its flight deck. It offers a detailed chronicle of day-to-day operations, including advancements in ASW tactics and the deciphering of Germany's Enigma Naval Code, which empowered the U.S. Navy forces in the Atlantic to take the offensive.
