UNITAS is a longstanding, multinational maritime exercise conducted annually in Latin America and the Caribbean to enhance security cooperation and improve coalition operations. UNITAS LXII was hosted by Peru from Sept. 24 - Oct. 6, 2021. U.S. forces, including two U.S. Navy ships and a submarine, joined more than 32 ships, four submarines and 26 aircraft from 19 partner nations for training operations off the coast of Lima and in the jungles of Iquitos.

UNITAS is designed to train forces to conduct joint maritime operations through the execution of littoral warfare, anti-piracy, maritime interdiction operations, countering transnational organized crime, anti-surface warfare, electronic warfare, communications exercises, and air and amphibious operations that increase interoperability and capability between participating naval and marine forces. 

UNITAS develops and sustains relationships that improve the capacity of our reemerging and enduring maritime partners to achieve common objectives. Additionally, the military-to-military exchanges foster friendly, mutual cooperation and understanding between participating navies and marine corps.   

Training Scenarios

UNITAS LXII included scenarios addressing electronic warfare, anti-air warfare and air defense, anti-surface warfare, live fire, maritime interdiction, littoral operations, and jungle training. 

The exercise consisted of three phases: at sea, amphibious, and amazon. The maritime domain included the littorals which incorporates not only the ocean, but also the area inland from the shore that can be supported and defended directly from the sea. The majority of the land training took place at areas along the coast where marines and naval infantry will train in support of greater naval operations. The amphibious phase consisted of a landing from naval vessels and the amazon phase simulated an environment supported from the sea. The Amazon phase was hosted by the Peruvian Marine Corps at established training sites. This environment offered jungle and riverine training that are key aspects of maritime operations.
