The deployment of multiple unmanned systems is new to UNITAS but will become the standard as NAVSOUTH/4th Fleet takes lessons learned to inform the Navy’s hybrid fleet coming in the next decade. Specific to UNITAS LXIV, the Navy deployed and exercised several unmanned systems to enhance maritime domain awareness, conduct battle damage assessment in support of the UNITAS LXIV live-fire sink exercise, or SINKEX, and integrate unmanned system operations with partner nation navies.

Unmanned Systems training: In April the Secretary of the Navy and the Chief of Naval Operations announced that the Navy will scale unmanned systems to the fleet level by operationalizing unmanned systems in the U.S. The amphibious phase consisted of riverine operations and culminated in a landing from naval vessels. The majority of the amphibious training took place along the coast where marines and naval infantry trained in support of greater naval operations. 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. UNITAS LXIV consisted of two concurrent phases: at sea and amphibious.

UNITAS' challenging training addresses key aspects of multinational and combined operations such as technology standardization and common operating procedures. Training included scenarios addressing electronic warfare, anti-air warfare and air defense, anti-surface warfare, live fire, maritime interdiction, littoral operations, and amphibious operations. Southern Command’s area of responsibility. UNITAS, which is taking place in Colombia this year, is the world’s longest-running annual multinational maritime exercise that focuses on enhancing interoperability among multiple nations and joint forces during littoral and amphibious operations in order to build on existing regional partnerships and create new enduring relationships that promote peace, stability, and prosperity in the U.S.

During UNITAS, reconnaissance and special operation force Marines from 11 partnered and allied nations conducted multilateral special operations training consisting of HRST, room clearing, visit board search and seizure, jungle patrolling, low level static line jumping, and small arms tactics. reconnaissance Marine with 4th Reconnaissance Battalion, 4th Marine Division, fast ropes from a UH-1Y Venom during helicopter rope suspension tactics training during UNITAS LXIV at Cartagena, Colombia, July 13, 2023.
