The USS Hornet (CV-12) was an Essex-class aircraft carrier constructed for the United States Navy during World War II. Laid down on August 3, 1942, by Newport News Shipbuilding, she was launched on August 30, 1943, and commissioned on November 29, 1943. As part of the larger Essex class, Hornet measured approximately 872 feet overall length, later revised to 888 feet in the long-hull subclass, with a beam of 93 feet and a deep load draft of around 30 feet 10 inches. Displacing about 27,100 long tons at standard load, she was powered by four geared steam turbines driving four shafts, capable of reaching speeds of 33 knots, with a range of over 14,000 nautical miles at 20 knots. Her flight deck was about 862 feet long and 108 feet wide, supporting a hangar below measuring 654 by 70 feet. Hornet was initially equipped with a single hydraulic catapult and arresting gear for landing aircraft over both stern and bow, with a complement of over 2,500 crew members, though actual numbers often exceeded this. Her armament included a main battery of twelve 5-inch dual-purpose guns and extensive anti-aircraft defenses comprising quadruple 40mm Bofors guns and numerous 20mm Oerlikon cannons. Armor protection featured a 4-inch waterline belt, 2.5-inch hangar deck, and a 1.5-inch deck below, providing vital protection for her vital systems. Hornet's wartime service was distinguished by participation in major Pacific campaigns, including attacks on New Guinea, Palau, Truk, the Mariana Islands, and the Philippines, notably during the Battle of the Philippine Sea. She played a key role in the "Great Marianas Turkey Shoot," and was involved in the sinking of several Japanese ships, including carriers and cruisers, through air strikes. She was badly damaged by Typhoon Connie in June 1944, necessitating repairs in the United States. Post-war, Hornet supported Operation Magic Carpet, returning troops to the U.S., and was placed in reserve in 1946. Reactivated for the Korean War, she was modernized to operate jet aircraft and later converted into an anti-submarine carrier. During the Vietnam War, she provided air support and participated in reconnaissance, notably recovering Apollo 11 and Apollo 12 astronauts upon their return from the Moon. Decommissioned in 1970, Hornet was designated a National Historic Landmark and opened as the USS Hornet Museum in Alameda, California, in 1998. Her enduring significance lies in her extensive combat record, technological advancements, and role in space recovery missions, marking her as a prominent vessel in naval and aerospace history.
