While, World War II ended in 1945, the next 4 years were the "zone" era with the country into the "US Zone", "Russian/Soviet Zone", "British Zone", and "French Zone", and it was 1949 when the East/West division replaced the zones.

A revolutionary hull design, based on the planned "Montana"-class battleship , gave her enhanced protection compared to previous carriers.  She operated for 47 years, during which time she saw action in the Vietnam War and served as the Persian Gulf flagship in 1991's Operation Desert Storm.  Decommissioned in 1992, she is now a museum ship at the USS "Midway" Museum, in San Diego, California, and the only remaining U.S. aircraft carrier commissioned right after World War II ended that was not an "Essex"-class aircraft carrier .
