Supermarine Seagull (1921)

what is it?

The Supermarine Seagull was a flying boat produced by the British aircraft manufacturer Supermarine. It was developed by Supermarine's chief designer R.J. Mitchell from the experimental Supermarine Seal II. Development of the Seagull started during 1920. In June 1921 it was evaluated for military applications but was rejected, and so Supermarine developed the aircraft as a private venture.
