World War I
A monoplane is an aircraft design featuring a single main wing, which is the primary lift-generating surface. This design became prominent in the early 20th century, especially during World War I, as it offered advantages in terms of weight, speed, and maneuverability compared to biplanes that had two wings. The shift to monoplanes represented a significant advancement in aviation technology, contributing to the rise of air combat and changing military tactics in the war.
