RIMPAC 2026 puts Peru and Chile in command roles, testing US-led naval hierarchy
For the first time in RIMPAC history, a Peruvian officer is commanding the Amphibious Task Force and a Chilean commodore is serving as deputy commander of the entire Combined Task Force near Hawaii. The shift gives Latin American navies unprecedented responsibility alongside US Navy SEALs and other specialists, quietly reshaping who leads in the world’s largest maritime exercise.
When a Peruvian officer takes charge of the Amphibious Task Force at RIMPAC and a Chilean commodore serves as deputy commander of the entire Combined Task Force, the message is bigger than any single drill off Hawaii. The United States is sharing real command authority at its flagship naval exercise with partners once seen mainly as junior participants, and that redistribution of responsibility carries both human and strategic weight.
During the 2026 iteration of the Rim of the Pacific Exercise near Hawaii, US Navy SEALs have been training and operating alongside personnel from Peru and Chile in a complex multinational environment. According to details released on 23 August, the Latin American contingents have assumed unusually prominent leadership posts: the Peruvian officer leading amphibious operations, and the Chilean commodore acting as the number two for the combined fleet. They worked closely with traditional US naval elements, explosive ordnance disposal teams, and other specialized units, taking on what were described as “massive leadership roles.”
For the individual officers and sailors involved, these are career-defining responsibilities. Commanding amphibious forces at RIMPAC means coordinating ship movements, landing operations, and logistics under intense scrutiny from dozens of partner navies. Serving as deputy commander of the Combined Task Force requires balancing national interests, alliance politics, and real-time operational decisions in an environment designed to simulate wartime complexity. It is a test not only of tactics, but of trust.
Operationally, the arrangement gives Peru and Chile a front-row role in shaping how RIMPAC’s amphibious and fleet maneuvers are planned and executed. Their staffs must integrate procedures, communications systems, and rules of engagement across ships and units flying many different flags. For US SEALs and other American specialists, working under or alongside non‑US commanders in certain scenarios is part of adapting to future conflicts where the United States may prefer to let partners take the visible lead, especially near their own regions.
Strategically, elevating Latin American officers into these roles strengthens Washington’s web of relationships in a hemisphere where Chinese economic and diplomatic influence has been expanding. It sends a signal that regional navies are not merely recipients of US training, but co‑owners of security architectures that stretch from the Pacific to the Southern Cone. For Peru and Chile, the assignments translate into greater clout when they return home, potentially shaping procurement decisions, doctrine, and how their governments think about blue‑water operations.
This shift also tests the flexibility of a US‑led naval hierarchy built over decades. Sharing command in a high‑profile setting requires the United States to accept different leadership styles, language barriers, and national caveats while still ensuring that the exercise meets its own objectives. Other partners are watching closely to see whether similar opportunities will open up for their officers in future iterations — and whether leadership is truly shared, or merely delegated under tight American control.
The human stakes ripple beyond admirals and captains. Sailors and marines from across the Pacific must learn to trust orders coming from unfamiliar accents and uniforms, knowing that in a real crisis their lives could depend on seamless multinational coordination. For smaller navies, successfully managing complex segments of RIMPAC can bolster morale at home and justify investments in new ships and training.
One way to think about this evolution is that RIMPAC is turning from a US‑run rehearsal into a laboratory for shared command — a place where Washington tests how far it can push its partners forward without losing strategic coherence. That experiment matters in a world where the US expects allies to carry more of the visible burden, from the South China Sea to the Caribbean.
The next indicators to watch will be whether Peru, Chile, and other regional navies secure follow‑on roles in smaller multinational deployments, humanitarian missions, or freedom‑of‑navigation patrols; whether future RIMPACs institutionalize these command rotations; and how China and other non‑participants adjust their own naval diplomacy in response to a more empowered set of US partners in the Pacific and Latin America.
