Britain and the United States used the Curtiss SO3C Seamew.
The SO3C was only used for 2 years. Due to their poor service they were converted into target drones. Their replacement was the Curtiss SOC Seagull biplanes that were brought out of mothballs.
The United Kingdom gave the SO3C the name Seamew, which replaced what it was originally called, the Seagull.
The Royal Navy was delivered 100 out of 250 Seamews ordered. They were used only for training.
