USS Iowa (BB-61) in Los Angeles
USS Iowa (BB-61) was the lead ship of her class of battleship and the fourth in the United States Navy to be named in honor of the 29th state. Owing to the cancellation of the Montana-class battleships, Iowa is the last lead ship of any class of United States battleships, and was the only ship of her class to have served in the Atlantic Ocean during World War II.
During World War II, she carried President Franklin D. Roosevelt across the Atlantic to Casablanca en route to a crucial 1943 meeting in Tehran with British Prime Minister Winston Churchill and Soviet leader Josef Stalin. She has a bathtub — an amenity installed for Roosevelt, along with an elevator to shuttle him between decks. When transferred to the Pacific Fleet in 1944, Iowa shelled beachheads at Kwajalein and Eniwetok in advance of Allied amphibious landings and screened aircraft carriers operating in the Marshall Islands. She also served as the Third Fleet flagship, flying Adm. William F. Halsey's flag at the Japanese surrender in Tokyo Bay.
