The Latécoère 300 series of aircraft were a group of civil and military flying boats. They were manufactured by French aircraft manufacturer Latécoère in the 1930s. A single Latécoère 300 was built; it was flown for the first time in 1931 and sank the same year. It was rebuilt and flown again in 1932 being named Croix du Sud. The 300 was a monoplane of parasol wing construction. It was powered by four engines each of which produced 650 hp arranged in two push-pull pairs.
Made by Groupe Latécoère.
