A10 Warthog drops flares after refueling at KC-135 Stratotanker. A flare or decoy flare is an aerial infrared countermeasure used by a plane or helicopter to counter an infrared homing (“heat seeking”) surface-to-air missile or air-to-air missile.
In this video, a KC-135 Stratotanker assigned to the 340th Air Refueling Squadron with the 451st Air Expeditionary Group at Kandahar Airfield refuels an A-10 Thunderbolt II assigned to the 75th Expeditionary Fighter Squadron, Nov. 18, 2018.
The Republic A-10 Thunderbolt II is a single-seat, twin turbofan engine, straight-wing jet aircraft developed by Fairchild-Republic for the United States Air Force (USAF). Usually pointed to by the nicknames “Warthog” or “Hog,” its official name comes from the Republic P-47 Thunderbolt, a World War II fighter-bomber effective at attacking ground targets.
Flares are used to distract heat-seeking missiles.
