The Me-262 fighter, nicknamed Schwalbe and translated as Feiyan, was a jet fighter developed by Germany before World War II and the first jet fighter in human aviation history to be used in combat. The aircraft is equipped with jet engines and adopts a swept back wing aerodynamic layout, representing a new direction in the development of fighter jets and also opening a new page in the history of air combat. Although the Me-262 fighter jet was seen as the last resort of the Nazi German Air Force in dire straits, and its production quantity fell far short of the demand to turn the tide of the war, less than a year of actual combat proved that it was a powerful combat aircraft.

The Bf-109 fighter was a single seat, single engine, single wing, all metal piston fighter jet from Germany. It was one of the main fighter planes of the Nazi German Air Force during World War II and also one of the most outstanding light fighters in terms of comprehensive performance. The Bf-109 fighter jet features wings located beneath the fuselage, a full face cockpit, retractable landing gear, and a body and wings made entirely of metal. It belongs to the new generation of fighter jets and outperforms the Zero fighter jet in terms of performance, making it the most widely used military aircraft by Axis air forces. The Bf-109 fighter jet was designed by Messerschmitt, a designer at the Bavarian Aircraft Works in Germany.
