The new Fourth Fleet is focused on Latin America and could become a model for other commands.
Major changes are under way in the U.S. Southern Command (SOUTHCOM), which is altering its traditional military responsibilities. More focus will be placed on humanitarian relief efforts and cooperative military engagements; less on the security assistance and defensive procedures of the past 45 years. This reflects a new Navy-wide emphasis on soft power and coincides with the establishment of a Fourth Fleet (headquartered in Mayport, Florida) to execute the new objectives.
