The Cruzeiro do Sul Exercise (CRUZEX) is the largest exercise in South America and attracts participants from all over the continent as well as the USA. The exercise was first held in 2002 and 2024’s edition is the ninth.
The exercise is largely based at Natal Air Base which offers extensive facilities, uncrowded skies and a large geographical area – 200 by 200 nautical miles.

CRUZEX 2024 took place from 3rd November to 15th November and brought together 16 countries, more than 3,000 personnel, more than 100 aircraft and involved over 1,500 flight hours.

CRUZEX 2024 was the largest multinational war training exercise held in Latin America, led by the Brazilian Air Force, with the participation of the Brazilian Army and Navy. Many missions were undertaken, including ground attack, air superiority, escorting, and in-flight refuelling. However, the primary objective was to integrate and enhance the ability to work together of multiple countries with multiple equipment types.

The Brazilian Air Force introduced two new elements into its operations for the 2024 exercise: the cyber and space domains. The former featured simulated exercises that expanded training by integrating cyber and air operations, testing the security of critical systems that support aerospace activities. The latter included realistic simulations of space-related events that directly influenced decision-making and, consequently, the course of a conflict.

Participating in the 2024 Exercise were Brazil, Argentina, Canada, Chile, Colombia, Ecuador, France, Germany, Italy, Paraguay, Peru, Portugal, South Africa, Sweden, Uruguay, and the United States.

Foreign countries participating with aircraft were as follows:

Argentina with two Pampa III from each of Grupo Aéreo 6 de Caza based at Tandil and Escuadrón X of Grupo Aéreo 10 de Caza based at Rio Gallegos and a KC-130H Hercules from I Escuadrón Grupo Aéreo 1 based at El Palomar.
