In the event of an emergency, Navy’s Wide Area Alert Network (WAAN) provides real-time alerts to the Navy community throughout the lifecycle of the incident/crisis or closure through:
4 Methods
- Giant Voice (GV)—A voice announcing system using exterior speakers, commonly termed “Giant Voice”
- Interior Voice (IV)—Interior speakers or sirens
- Computer Desktop Network System (CDNS)—An administrative broadcast across Navy computer networks that overrides current applications, thereby reaching all Navy users almost instantly. It works whenever you are logged in to your NMCI or One Net computer.
- Automated Telephone Network System (ATNS)—Interactive, community Network system capable of providing voice and/or data messages to multiple receivers—telephones, cellular phones, email, SMS (Text), etc. ATNS requires registration.

Bottom Line Up Front (BLUF)—It’s a requirement.
- All military (active duty and Reserve), civil service, and contractor personnel with an NMCI or One Net user account are required to register their office email address and phone number, at minimum, in the WAAN. Registering personal emergency contact information also is strongly encouraged.
- Personnel are not automatically registered in the WAAN.
- Navy can’t alert you, if they can’t find you!
