The Curtiss SO3C Seamew was developed by the Curtiss-Wright Corporation as a replacement for the SOC Seagull as the United States Navy's standard floatplane scout. Curtiss named the SO3C the Seamew but in 1941 the US Navy began calling it by the name Seagull, the same name as the aircraft it replaced, causing some confusion. The British Royal Navy kept the Curtiss name, Seamew, for the SO3Cs that they ordered. One of the US Navy's main design requirements was that the SOC Seagull's replacement had to be able to operate both from ocean vessels with a single center float and from land bases with the float replaced by a wheeled landing gear.

The Curtiss-Wright Corporation is a manufacturer and services provider headquartered in Davidson, North Carolina, with factories and operations in and outside the United States. Created in 1929 from the consolidation of Curtiss, Wright, and various supplier companies, the company was immediately the country's largest aviation firm and built more than 142,000 aircraft engines for the U.S. military during World War II.
