A fighter is designated to have superiority over aircraft of any other class. Speed is one of the most important components of success. During the Second World War the maximum speed of serial fighters significantly increased. However, the propeller was capable of bringing aircraft only to a certain limited speed. The way out was found in the creation of a principally new type of engine - the jet engine.
