Navy Distance Support

The Navy Distance Support program office, through its Navy 311 initiative, offers the Fleet, Sailors, military families, and civilians on-demand information assistance for non-emergency, non-tactical issues via phone, email, web, text, chat, and other channels. The Navy 311 capability is modeled after "3-1-1" non-emergency services currently active in more than 300 major cities worldwide. Navy 311 (formerly known as the Global Distance Support Community (GDSC)), builds upon the existing infrastructure that has supported the Navy's Global Distance Support Community since 1999.
