Kawanishi N1K1 Kyofu (Mighty Wind) REX

Many countries used floatplanes for scouting and reconnaissance duties, and to hunt submarines and surface ships, but only Japan built and fielded fighters on floats intended to gain air superiority above a beachhead to support amphibious landing operations where carrier or land-based fighters were unavailable. The Kawanishi N1K1 (Allied codename REX) was the only airplane designed specifically for this purpose to fly during World War II.
