When an unexpected military attack initiated by the Japanese Navy Air Service on America's naval base in Pearl Harbor jolted the entire nation, it spurred the United States' entry into World War II, thus changing the history of the world as people knew it. The attack caused subsequent world-changing events, and rendered this naval base in Hawaiʻi a crucial part of American history and heritage. Today, Pearl Harbor is dominated by five historic sites that serve as solemn reminders of this day in American history. The USS Arizona Memorial, Battleship Missouri Memorial, USS Bowfin Submarine Museum Park, USS Oklahoma Memorial and the Pacific Aviation Museum are all part of the site of this war incident. The USS Arizona Memorial in particular pays homage to the sunken vessel.
