"After fifteen years of emphasizing sustained operations ashore, the Marine Corps is refocusing on its naval and expeditionary roots and full-spectrum operations across the ROMO [range of military operations]. The Marine aviation portfolio continues to evolve as we address the challenges and trends of the current and future operational environment. Over the next five years, as Marine aviation continues with its modernization plan, the MAGTF's [Marine Air Ground Task Force] Aviation Combat Element will enter the heaviest years of aircraft transition in history. [...] We continue to develop and deploy our fleet of unmanned aircraft systems. The RQ-21 is being upgraded to provide additional sensor and platform capabilities, while deploying organically with Marine Expeditionary Units. The Marine Corps' Group 5 sea-baseable UAS-the Marine Unmanned Expeditionary (MUX)-has been formally approved by the Joint Requirements Oversight Council and will see major investment across the FYDP [Future Years Defense Program] in order to field this capability in the mid-2020s. Our expeditionary enablers are modernizing as well. We will introduce G/ATOR radars, replacing five of the Marine Corps legacy systems and providing a significant upgrade in capabilities. We will also field the Common Aviation Command and Control System (CAC2S) to better integrate aviation command and control functions."
