21 June 1933 – first flight of Supermarine Seagull V / Walrus

On 21st June 1933, the British single-engine amphibious biplane Supermarine Seagull V (later known also as Walrus), performed its maiden flight.

The aircraft was developed as a private venture of the Supermarine company, designed by the well-known aeroplane constructor, R.J. Mitchell. The Walrus was, with the highest probability, the first amphibian flying boat in the world to be launched with catapult.

A detailed history of the Seagull V / Walrus development and operation can be found in our Supermarine Seagull V / Walrus article, issued at the beginning of June 2024, within Photo of the Week series.
