The first F4U Corsairs were developed in the late 1930s which featured the visually unique gull wing design. This was the result of an engineering trade-off to provide the longest propeller and the shortest practical landing gear strut. For carrier landings, the longer the strut, the heavier and more vulnerable the gear is to impact stresses. Nevertheless, the F4U packed a huge engine under that long nose and the only way to translate all of that horsepower into thrust was by turning as large a propeller as possible. To provide the greatest ground-handling stability, the landing gear had to be spaced as far apart as practical. These requirements summed together yielded the now familiar gull wing design that, in turn, translated into a tough aircraft that would not only see combat through the end of WW2, but also serve on the front lines during the early years of the Korean War.
