Vought XSO2U - The Vought XSO2U was an American observation floatplane developed by Vought-Sikorsky for the United States Navy during the late 1930s. Intended to replace the Curtiss SOC Seagull in service as a scout aboard cruisers it proved superior to the Curtiss SO3C in evaluation but failed to win a production contract due to Vought's lack of manufacturing capacity.
