The USS Midway Museum, docked in San Diego, is the most popular naval warship museum in the United States and among the most visited museums in the country, with 1.4 million people annually coming aboard. Those visitors discover the Midway made its own fresh water while at sea, from the first day it was commissioned in 1945 until it was taken out of active service in 1992. But when this venerable aircraft carrier found new life as the USS Midway Museum in 2004, its relationship with water entered a new era as well.
