As a midshipman at the Naval Academy in the early 1930s, excelled at soccer and lacrosse and acquired the nicknames "Bub" and "Cocky.” After graduation in 1935, he served the heavy cruiser USS Salt Lake City (CA-25) before attending submarine school. In the ensuing years he was in several submarines, including the USS S-26 (SS-131) and USS R-4 (SS-81) before the war; USS Seadragon (SS-194), which he was on board when Cavite was attacked in December 1941; USS Gato (SS-212), in which he was executive officer; and USS Guardfish (SS-217), which he commanded in 1943-44. During the last year of World War II he was on the staff of Commander Submarine Force Pacific Fleet as assistant to operations officer Richard Voge. Following the end of the war he had occupation duty in Japan and then commanded the submarine USS Irex (SS-482). Subsequent assignments included duty at the Naval Academy, the staff of Commander Submarine Flotilla One, and command of the destroyer USS Yarnall (DD-541) during the Korean War. Later in the 1950s he was a student at the Armed Forces Staff College, a member of the staff of Commander Second Fleet, and a student at the National War College. Sea commands included the oiler USS Nantahala (AO-60), Submarine Squadron Five, and Submarine Squadron 14. The latter was the first squadron of Polaris ballistic missile submarines.
