The Blohm & Voss Ha 140 was a German multi-purpose seaplane first flown in 1937.

It was intended for use as a torpedo bomber or long-range reconnaissance aircraft but did not enter production.

The crew consisted of a pilot and radio operator, with a gunner in a revolving turret in the nose or in a second gun position to the rear.

However, by then B&V did not have enough spare manufacturing capacity for series production and declined the order, which went to Heinkel instead.

[1] In 1940 the third prototype was modified to test the tail design and variable-incidence wing mechanism used on the BV 144 transport.
