The KC-135 Stratotanker is a military aerial refueling aircraft developed by Boeing. It was first introduced in the 1950s and has been a vital part of the United States Air Force's operations. The aircraft can refuel various types of military planes in flight, extending their range and operational capabilities. Equipped with a boom system and hose-and-drogue method, the KC-135 can support multiple aircraft simultaneously. It has played a crucial role in numerous conflicts, ensuring that fighter jets and bombers, such as the F-16 Fighting Falcon and B-52 Stratofortress, can remain airborne longer during missions.
