Maintaining the KC-135
The KC-135 Stratotanker provides aerial refueling capability for the Air Force, Navy, and Marine Corps and has done so for over 50 years. There are currently 16 KC-135s stationed at MacDill Air Force Base, Fla. It can hold up to 200,000 lbs. of fuel and can double as a medical evacuation aircraft.
