Supermarine Baby
The Supermarine Baby (also called the Supermarine N.1B Baby) was a First World War fighter aircraft that was the earliest example of a single-seat flying boat fighter to be built in the United Kingdom. It was designed by Supermarine to meet a 1917 Navy Board specification which stipulated the aircraft have a speed of 95 knots (176 km/h; 109 mph) and a ceiling of 20,000 feet (6,100 m), and be capable of being launched from ships at sea.
