Identification: KC-135s are refueling tankers recognized by the refueling nozzle tucked under the tail and the four jet engines under the wings (four, not two as in the KC-10). All of these tankers have one refueling nozzle under the tail, but some are fitted with nozzles on the wing tips, permitting them to refuel two aircraft at once. Click links for more photos.
