Bogan authored a confidential memorandum that was leaked by Captain John G. Crommelin during the Revolt of the Admirals in September 1949. His memo described the situation in the Navy as follows, "The morale of the Navy is lower today than at any time since I entered the commissioned ranks in 1916 ... The situation deteriorates with each press release." The memorandum was endorsed in writing by Admiral Arthur W. Radford and Chief of Naval Operations Louis E. Denfeld. He retired as a Vice Admiral in 1950 at age 55 rather than transfer from command of First Task Fleet in the Pacific to commander of Fleet Air at Jacksonville, a command normally filled by a Rear Admiral.
In August 1963, Bogan was the captain of a 104 ft, $250,000, luxury yacht Freedom II when it sank in the Pacific Ocean 600 miles from California. The yacht was enroute from Honolulu to San Diego. Bogan and six crew members were rescued by the submarine . According to the crew, the yacht lost a wooden plank in its hull causing it to flood and sink, though it was unclear what caused the loss of the plank.
Bogan was inducted into the Naval Aviation Hall of Honor, 1992.
