Operation Atlas Overview
Operation Atlas is Brazil’s largest amphibious drill in a decade, integrating the Brazilian Navy, Marine Corps, Air Force, and Army for a coordinated maritime security and amphibious warfare test.
- Date of launch: 7 December 2025
- Location: offshore waters of the São Paulo‑Paraná maritime corridor, near Ilha da Marambaia (São Paulo state)
- Total personnel: 3,400 troops (including 1,800 marines, 800 navy sailors, 300 army engineers, 500 aircrew)
- Key objectives:
- Validate joint amphibious assault tactics against simulated coastal threats.
- Test integrated command‑and‑control (C2) platforms across services.
- Enhance maritime domain awareness in the South Atlantic.
Force Composition
| component | Units Involved | Primary Assets | Role |
|---|---|---|---|
| Marine Corps | 1st Amphibious Brigade, 2nd Marine Infantry Battalion | L‑UAVs, amphibious assault vehicles (AAV‑7 A1), 6 × landing craft | Beachhead seizure & ground maneuver |
| navy | 1st and 3rd Marine Expeditionary Forces, Naval Aviation Squadron 1 | 2 × air‑craft carriers (NAe São Paulo, nae Bahia), 4 × frigates, 12 × Corvette-class patrol vessels, 8 × submarines (Riachuelo‑class) | Sea control, fire support, logistics |
| Air Force | 1st Aerial Refueling Wing, 2nd Transport Group | 4 × KC‑135R, 6 × C‑130H Hercules, 8 × A‑29 Super Tucano | Airlift, aerial refueling, close‑air support |
| Army | 5th Engineer Battalion, 8th Logistics Regiment | Heavy‑lift helicopters (CH‑47F), 2 × M113 APCs | Engineering support, obstacle breaching, supply chain |
Timeline of Key Phases
- Phase I – Maritime Approach (Day 1‑2)
- NATO‑style seaborne convoy formation.
- Real‑time satellite‑linked ISR from the Brazilian Space Agency’s Amazonia‑5 satellite.
- Phase II – Amphibious Assault (Day 3‑4)
- landing Craft air Cushion (LCAC) vehicles launch at 0400 h.
- AAV‑7 A1 units conduct a “beach‑to‑interior” maneuver, securing Objective Alpha (simulated port facility).
- Phase III – Consolidation & Sustainment (Day 5‑7)
- Logistics over‑the‑shore (LOTS) operations establish a temporary forward operating base (FOB).
- Joint fire support from naval gunfire, ship‑borne missiles, and close‑air support.
- Phase IV – Extraction & Assessment (Day 8)
- Rapid withdrawal using air‑mobile lift and amphibious evacuation techniques.
- Comprehensive after‑action review (AAR) conducted by the Brazilian Integrated Defense System (SISDEF).
Strategic Benefits
- Enhanced joint interoperability: Demonstrates seamless C2 integration between naval, ground, and air components, reducing reaction time to maritime threats.
- Improved amphibious capability: Validates Brazil’s ability to project power across 200 km of coastline, crucial for protecting offshore oil platforms and fisheries.
- regional deterrence: Sends a clear signal to potential adversaries in the South Atlantic about Brazil’s maritime dominance and defense readiness.
Practical Lessons & Recommendations
- Command‑and‑Control (C2) Synchronization
- Deploy RED‑STAR tactical data link across all platforms to maintain a common operating picture (COP).
- Conduct pre‑exercise cyber‑hygiene drills to safeguard against electronic warfare.
- Logistics & Sustainment
- Prioritize modular supply packs for rapid distribution via LOT‑S (Logistics Over‑the‑Sea).
- Incorporate unmanned surface vessels (USVs) for resupply to reduce personnel exposure.
- Amphibious Equipment Upgrades
- Phase‑in next‑generation AAV‑8 R with improved armor and propulsion.
- Test electric‑drive LCAC prototypes for reduced acoustic signature.
Real‑World Context & Recent Developments
- Brazilian Navy’s 2024 acquisition of two Riachuelo‑class submarines expanded under‑sea surveillance, directly supporting Operation Atlas’s anti‑submarine warfare (ASW) component.
- International observers from UNITAS and US‑South American Command participated, providing cross‑training opportunities and reaffirming bilateral maritime cooperation.
