Supermarine Sea Lion I
The Supermarine Sea Lion I (originally called the Supermarine Sea Lion) was a British racing flying boat designed and built by Supermarine for the Schneider Trophy contest at Bournemouth, England, in September 1919. It was based on a version of the Supermarine Baby, the first single-seat flying boat fighter aircraft to be designed and built in the United Kingdom, that first flew in February 1918.
