The Ha 140 was a German multi-purpose seaplane of the 1930s. It was designed for use as a torpedo bomber or long-range reconnaissance aircraft.

Design and development

The Ha 140 was a developed as a twin-engine floatplane, with an all-metal structure and an inverted gull wing, similar to the larger Ha 139. 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. The torpedo or bomb load was accommodated in an internal bomb bay. Three prototypes were built, but the design was not carried any further, as the similar Heinkel He 115 was selected for service.
