On December 1, 1968, Naval Security Group Detachment Sugar Grove was established. It became a Naval Security Group Activity (NSGA) when the Naval Radio Station was closed in November, 1995.

39 years ago, the Cryptologic Division Officer Course (CDOC) was first instructed to young and inspiring naval officers.  From the rank and number of officer instructors, to the length of CDOC and follow on training, this is how cryptologic officer training priorities and investment looked like in 1986.

Christian Andreas Doppler was an Austrian physicist and mathematician whose 1842 description of what we now call the Doppler Effect fundamentally changed the understanding of wave phenomena. His insight—that the observed frequency of a wave depends on the relative motion between the source and the observer—forms a cornerstone of modern physics, astronomy, and engineering.

In 1921, U.S. Army Brigadier General William “Billy” Mitchell demonstrated what many considered unthinkable at the time: aircraft could sink battleships. Under his direction, Army-Air Service bombers successfully destroyed decommissioned warships — including the former German battleship Ostfriesland and the U.S. Alabama — during highly publicized bombing trials, proving that aerial bombs posed a genuine threat even to heavily armored capital ships.
