Answer: Fleet Week
The first Fleet Week was celebrated in San Diego, California, during the 1935 California Pacific International Exposition. The years between World War I and World War II saw an increasing military build-up in both Japan and Germany, while the communist Soviet Union (USSR) was given over to the wave of Stalinist nationalism. Most United States citizens experienced little sense of urgency about foreign developments because of isolationism and concerns with the ongoing economic Great Depression. However, then-U.S. President Franklin D. Roosevelt, a former Assistant Secretary of the Navy, was intent on expanding the U.S. Navy in response to world political trends. A major aircraft company was moving to Lindbergh Field, (today more commonly known as San Diego International Airport). In this atmosphere, Fleet Week was born.
