This warship is named after John S. McCain, Jr., and John S. McCain, Sr., both Admirals in the United States Navy. John S. McCain, Jr., commanded the U.S. Navy submarines USS Gunnel and USS Dentuda during World War II. Subsequently he held a number of posts, rising to Commander-in-Chief of the United States Pacific Command before retiring in 1972. John S. McCain, Sr., commanded the aircraft carrier Ranger (CV-4), and acted as commander of the Fast Carrier Task Force during the latter stages of World War II. These men were the grandfather and father of John S. McCain III, former naval aviator captain, a U.S. Senator representing the state of Arizona, and the Republican nominee for President of the United States in the 2008 election.
