For several decades the Naval Security Group (NAVSECGRU) Command has been the Navy’s cryptologic organization, with responsibility for signals intelligence and communications security and with NAVSECGRU Activities scattered around much of the world.

But now the NAVSECGRU Command has been disestablished and all NAVSECGRU Activities and Detachments have been renamed as Navy Information Operations Commands (NIOCs) and Detachments (NIODs).

See OPNAV Note 5450, Disestablishing the Naval Security Group Command, December 29, 2005.

The Naval Security Group Command, headquartered at Fort Meade, Maryland, was designated by that name in 1968, according to Jeffrey Richelson’s The U.S. Intelligence Community (4th edition, p. 84).
