KC-135 Stratotanker

The KC-135 Stratotanker was first deployed in August 1956, and has been in operation since 1957. Though the KC-135 Stratotanker is mostly used to refuel planes in-flight, it can also transport cargo, perform reconnaissance work, or be used as an aerial command center. For medical emergencies, the Stratotanker can transport or evacuate patients. Above the fuselage-mounted fuel tanks, there’s a cargo and passenger deck.

Any airplane that is equipped for in-flight refueling can extend their operating range indefinitely. This makes tankers like the KC-135 Stratotanker invaluable for military operations. Though the Stratotanker is an asset of the U.S. Air Force, it’s sometimes made available to other military branches such as the Marine Corps and Navy as well as to other Allied countries’ aircraft.

Internal fuel from the KC-135 Stratotanker is pumped through the flying boom and exits a shuttlecock-shaped drogue that attaches to refueling aircraft. The Stratotanker’s boom operator controls the boom from the rear of the plane. Coordinating the movements of the Stratotanker and receiver airplane can be tricky, and is especially difficult in bumpy air.

From 1975 to 1988, Boeing replaced the original skin on 746 Stratotankers with a superior aluminum-alloy skin. Additional improvements included replacing the engine strut fittings, a number of parts and many thousands of steel fasteners and aluminum rivets.

Fuel efficiency as well as takeoff and carrying capacity were increased for Air Force Stratotankers with the replacement of the original KC-135A engines with CFM56 engines. Those planes were redesignated as KC-135R. The newer engines were also less noisy with reduced emissions. Engines in Air National Guard and Air Force Reserve Stratotankers were replaced with refurbished JT3D engines that had originally been installed in 707 commercial airliners. Those modified Stratotankers were redesignated KC-135E.

Airbus opened for business in 1970, and by 2006 had grown to employ 55,000 people. Airbus manufactures aircraft that have more than 100 seats. Based in Toulouse in France, Airbus is an European Aeronautic Defence and Space Company. They produce 14 different aircraft, including the A380, which will have seating for 555 people and be the world’s largest civil airliner.

Airbus also manufactures aerial tankers used for military transport and in-flight refueling. Airbus plants are located across Europe. Each plant manufactures various sections of the aircraft, which are completely assembled in Toulouse and Hamburg.

New Plane Design for Mid-Air Refueling

The idea of refueling mid-flight is not a new one. Yet previously this task was left up to modified civilian aircraft that were kitted out for the task. Though the concept was used mainly in the military, it would seem that mid-air refueling has a number of practical applications for civilian aircraft.
