The KC-135 Stratotanker is an aircraft that is used by the United States. The purpose of the KC-135 is to allow for refueling in the air. While you may think that an aircraft that provides this advanced of an ability probably has not been around for very long, that actually isn’t true in terms of the KC-135. In fact, the United States has been using this type of aircraft all the way since back in 1957 (the aircraft’s very first flight in a non-service situation was even further back, occurring on the 31st of August in 1956).
In addition to this aircraft being used by the United States Air Force, there are several other Air Forces who take advantage of the capabilities that this aircraft offers. Currently, the other Air Forces that also use the KC-135 are the Turkish Air Force, French Air Force and the Republic of Singapore Air Force.
Since they were first introduced back in 1957, there have been eight hundred and three of these airplanes built. When you take into account that each one of these aircraft costs just under forty million dollars to build, that is a significant amount of spending on this aircraft!
I have always enjoyed learning about different kinds of aircraft, and although the KC-135 isn’t my favorite aircraft, I do think that it is a very well built machine. This machine has obviously seen a lot of activity over the years, and for that reason you have to give it and its creators credit for successfully filling a quite important need.
