A light fighter or lightweight fighter is a fighter aircraft towards the low end of the practical range of weight, cost, and complexity over which fighters are fielded. The light or lightweight fighter retains carefully selected competitive features, in order to provide cost-effective design and performance.
The General Dynamics YF-16 and Northrop YF-17 were competing designs in the US Lightweight Fighter program.

The German Bf 109 was the second smallest major fighter of WWII, and produced in greater numbers than any fighter in history.
The Japanese A6M2 Zero was the lightest major fighter of WWII. Extremely maneuverable and long range, it was highly successful early in the war, though surpassed in the later stages.
Fighter aircraft are military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield permits bombers and attack aircraft to engage in tactical and strategic bombing of enemy targets.
