A U.S. Air Force C-17A aircraft, call sign RCH600 and tail number 07-7187, departed Langley Air Force Base in Virginia en route to Aguadilla Rafael Hernandez Airport in Puerto Rico, according to LatAmMilMVMTs on X during the reporting window from 8:16 p.m. to 8:45 p.m. UTC on December 15. The flight, tracked under hex code AE20C8, adds to recent U.S. military aircraft movements in the Caribbean region. LatAmMilMVMTs reported the departure from KLFI to TJBQ in a post timestamped within the 29-minute window. This development follows a U.S. C-17A (RCH426) departure from Pope Army Airfield to Santo Domingo's Las Américas Airport earlier on December 15, as noted in the previous reporting period. Satellite imagery had shown an increase in U.S. Air Force KC-135R Stratotankers at Las Américas, per Flightwatcher1 on X. These aircraft activities occur amid Venezuela's state oil company PDVSA reporting network disruptions due to hacking and the government's suspension of natural gas contracts with Trinidad and Tobago over a U.S. oil seizure on December 10, according to official statements and Bloomberg reports from earlier today.
