The C.710 were a series of light fighter aircraft developed by Caudron-Renault for the French Air Force just prior to the start of World War II. One version, the C.714, saw limited production, and were assigned to Polish pilots flying in France after the fall of Poland in 1939. A small number was also supplied to Finland.

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.
