The USS Midway was the longest-serving aircraft carrier in the 20th century. Named after the climactic Battle of Midway of June 1942, Midway was built in only 17 months, but missed World War II by one week when commissioned on September 10, 1945. Midway was the first in a three-ship class of large carriers that featured an armored flight deck and a powerful air group of 120 planes.
