Bloch MB.480

1st Flight 1939

The Bloch MB.480 was a French twin-engined torpedo-bomber/reconnaissance floatplane designed just before the start of the Second World War.

Only two were built, the French Navy deciding to use landplanes instead.

The first prototype was destroyed after colliding with a pier on Étang de Thau on 23 June 1940, while the second prototype was placed into storage in July, and was not flown again.
