"The Naval Security Group traces its historical origins to OP-20-G, the Navy radio intelligence organization established in the early 1920s by Laurence F. Safford, the "Father of Navy Cryptology." Tasked with providing communications intelligence on the Japanese Navy, the unit is credited with breaking the Japanese code JN-25 and changing the course of the war at the Battle of Midway in the Pacific during World War II. Thus the Naval Security Group has a long and rich history of providing essential knowledge of enemy intentions to national and naval leadership in every conflict for the last eight decades."
