As aircraft carrier USS Nimitz (CVN 68) begins its ‘Southern Seas 2026' exercise deployment in the US Southern Command (SOUTHCOM) area of responsibility (AOR), US officials are underscoring the ship's importance for Western Hemisphere protection.

“Its presence in the region reflects a shared commitment to the safety and protection of our people from mutual threats, including narcotics, weapons, and human smuggling,” Ron Johnson, US ambassador to Mexico, said in a statement released on 24 March by the US Embassy in Mexico.

“It also offers maritime forces across the region an opportunity to improve co-ordination, collaboration, and interoperability with the US Navy [USN],” Johnson added. “This visit underscores … commitment to ensuring a secure and stable Western Hemisphere.”

Nimitz and Arleigh Burke-class guided-missile destroyer USS Gridley (DDG 101) are scheduled to conduct passing exercises and at-sea operations with partner nation maritime forces as the ships circumnavigate the continent of South America, according to a 23 March release by US Naval Forces SOUTHCOM and US 4th Fleet.

‘Southern Seas 2026' is the 11th iteration of the exercise to the region since 2007 and will include subject matter expert exchanges and provide the opportunity for distinguished visitors from partner nations to embark on Nimitz, the release said. Engagements are planned with Argentina, Brazil, Chile, Colombia, Ecuador, Peru, Mexico, El Salvador, Guatemala, and Uruguay, with port visits planned for Brazil, Chile, Panama, and Jamaica.
