McCain was born on August 29, 1936, at the Coco Solo Air Base in the then-American-controlled Panama Canal Zone[2] to Navy officer John S. "Jack" McCain, Jr. (1911–1981) and Roberta (Wright) McCain (b. 1912). His father and grandfather both eventually became United States Navy admirals,[3] and were the first father-son pair to both achieve four-star admiral rank.[4] His grandfather, Admiral John S. "Slew" McCain, Sr., was a pioneer of aircraft carrier strategy[5] who commanded all carrier forces in the Pacific Ocean theater of World War II, and led American forces into epic actions such as the Battle of Leyte Gulf, dying four days after the conclusion of that war.[4] His father was a submarine commander[4] decorated with both the Silver Star and Bronze Star.[5] McCain has Scots-Irish ancestry.[6]\\
