History

The LeO 45 emerged from a 1934 French Air Ministry requirement for a modern bomber. Although technically excellent, production was hampered by engine supply problems with the Gnome-Rhône 14N and the aircraft was still entering service in large numbers when France fell in June 1940.

Variants

LeO 451 was the main production version; the LeO 455 introduced more powerful Hispano-Suiza engines; over 450 were built by the armistice.

Where you'll see it

Operated by the Armée de l'Air in 1939–40 and later by Vichy French forces; some served with Free French and allied air forces post-1942.
