OVERVIEW

The 1650 Foreign Area Officer (FAO) designator identifies Restricted Line officers in the U.S. Navy who specialize in regional expertise, foreign-language proficiency, and political-military analysis. Navy FAOs serve as Naval Attachés in U.S. embassies, foreign-relations officers on combatant command staffs, security-cooperation officers, and politico-military planners on the Joint Staff and Office of the Chief of Naval Operations.

All FAOs are lateral-transfer officers from URL communities, typically transferring as Lieutenants or Lieutenant Commanders. Designation requires graduate education in regional/security studies (typically at the Naval Postgraduate School, College of International Security Affairs, or a partner civilian institution) plus achievement of professional language proficiency (Defense Language Proficiency Test 2/2 or higher) in a target regional language.

RESPONSIBILITIES

  • Serve as Naval Attaché or Assistant Naval Attaché at a U.S. embassy
  • Lead security-cooperation programs at a combatant command
  • Provide regional and politico-military analysis on Joint Staff or OPNAV staff
  • Maintain language proficiency and regional expertise

HISTORY

The Navy Foreign Area Officer community was formally established in 2006 as a permanent Restricted Line designator, modeled on the long-standing Army FAO program. Before 2006, regional and politico-military expertise was provided by URL officers on collateral duty, by attaché-only officers, or by Foreign Area Specialty Officers (an earlier subspecialty code) who returned to their parent communities after a single tour.

The post-9/11 demand for region-specific naval expertise — combined with the Navy's renewed focus on great-power competition in the Indo-Pacific and Europe — drove the decision to make the FAO a career-long, full-time community. The community has grown steadily since establishment and now provides regional expertise across all six geographic combatant commands and at every major U.S. embassy with a Defense Attaché Office, and supplies the senior politico-military advisors on the Joint Staff, OPNAV, and the Office of the Secretary of Defense.
