The Pacific Fleet Submarine Museum and campus recently completed a makeover. The museum was expanded and the interior was completely redesigned with three galleries that document the history of the United States Navy's Submarine Force during World War II, the Cold War, to the present day and into the future. There are many different exhibits the whole family can enjoy. The Submarine Force came of age during World War II. Although it comprised just 2% of the US Navy, it was responsible for sinking over five million tons of Imperial Japan's shipping vessels - about 60% of the total shipping sunk during the war. Bowfin's bell was missing after her move between San Diego and Seattle. In 1996, the bell resurfaced and was offered to the museum. Hanging in the World War II gallery of the museum are replicas of submarine battleflags of many submarines that fought in the Pacific.
