He married Roberta Wright, later known as Roberta McCain, and the couple raised three children.

Naval career and commands

McCain's service encompassed active duty through several major conflicts and high-level administrative and operational positions. He served in World War II and continued in senior roles through the Korean and Vietnam eras, advancing to the highest levels of naval leadership. His responsibilities combined fleet operations, alliance coordination and strategic planning across the Pacific theater.

Legacy, family and later life

Part of a multi-generation naval family—his father, John S. McCain Sr., was also a senior naval officer—McCain Jr.'s career is often remembered for its emphasis on discipline, professionalism and coalition work in the Pacific. His son, John McCain, became a naval aviator and later a prominent U.S. senator. Roberta McCain remained a public figure after his death.

McCain died in 1981 while traveling over the North Atlantic after suffering a heart attack. His decades of service left a mark on naval organization and on American military engagement in Asia-Pacific waters. Scholars and biographers frequently cite his tenure as an example of Cold War-era military leadership and its impact on later U.S. naval strategy.
