The Lioré et Olivier LeO 25 was a bomber aircraft produced in France in the late 1920s. It was a development of the LeO 20 and retained much of that aircraft's structure adding a new tail and liquid-cooled engines. The prototype was delivered to the Aéronautique Militaire amongst a batch of LeO 20s in 1928 for evaluation. This was redesignated LeO 252 in 1929 after an engine change and a second generally similar machine was purchased by Romania.
Made by Lioré et Olivier.
