In this month’s issue we feature extra coverage of submarine-related issues. The lead feature is authored by long-time Proceedings contributor and submarine officer Rear Admiral William J. (Jerry) Holland Jr., U.S. Navy (Retired). Admiral Holland examines the thinking about how the nuclear triad evolved and examines what the nation needs as a nuclear deterrent today. Over the years, Admiral Holland has won four prizes in the Naval Institute’s General Prize/Arleigh Burke Essay Contest and had more than 60 contributions published in Proceedings—from articles to commentaries to book reviews to letters to the editor (C&Ds). As a Navy captain, Admiral Holland served as the “Professional Notes” advisor to Proceedings. He defines in actions and deeds what it means to be a naval professional and a friend.
