A U.S. Air Force KC-135 Stratotanker provides aerial refueling to USAF F-22 Raptors and an F-15E Strike Eagle over undisclosed locations. The 340th Expeditionary Air Refueling Squadron is responsible for delivering fuel for U.S. and coalition forces, enabling a persistent 24/7 presence in its area of responsibility. The procedure allows the receiving airplane to remain airborne longer, extending its radius of action. Video includes footages of cockpit voice communications between pilots and boom operator.
