FLEX 2025 Operations

SAN SALVADOR, El Salvador (May 27, 2025) — Cooperative Security Location (CSL) Comalapa, in coordination with the Salvadoran Navy, hosted the annual U.S. Naval Forces Southern Command / U.S. 4th Fleet Hybrid Fleet Campaign (HFC) Fleet Experimentation (FLEX) Event demonstrating combined/joint integration potential for unmanned systems during a showcase event in San Salvador, El Salvador.

In its 25th year of operation, CSL Comalapa's mission to combat transnational organized crime created the perfect opportunity to transition FLEX from partner nation observation to partner nation participation. King Air manned aircraft teamed with Resolute Eagle unmanned aircraft systems (UAS), Tsunami unmanned surface vessel (USV), Minotaur data fusion, and Lema expeditionary solar power to operate with Salvadoran navy Task Force Tridente from April 1 to May 23.

"Surface, aerial, and undersea autonomous systems stack together to give us highly effective maritime domain awareness. Part of what we've done here at Comalapa is advanced data fusion."

— Cmdr. Jon Williams, USNAVSOUTH Technology and Innovation Director

During FLEX, TF Tridente accomplished the interdiction and apprehension of narcotics smugglers with the assistance of this synchronized system. Practical tests showed the capability of single or combined systems to find, fix, track, assess, disrupt and pursue training targets from longer ranges with less exhaustion to manned interdiction crews.
