The resulting Fw 58 was a low-wing monoplane powered by a pair of Argus As 10C V-8 piston engines mounted in nacelles on the wing's leading edges.

Furthermore, the type was routinely operated in other capacities, including as a VIP transport, air ambulance, feeder airliner, photo reconnaissance and weather research aircraft.

[2] The Fw 58 was powered by a pair of Argus As 10C V-8 inverted air-cooled piston engines, capable of generating up to 240 PS (240 hp; 180 kW).

[2] It was quickly joined by the second prototype which, unlike the first, had been constructed to a military configuration; one of the more prominent visual differences between the two aircraft was the presence of defensive MG 15 machine guns in the nose and dorsal positions of the latter.

At least 30 specially configurated Fw 58s were deployed to the Eastern Front to spray potential sources of disease for German ground forces.

Numerous private pilots, including the aeronautical engineer Kurt Tank (who had headed the design of the Fw 58), operated the type as a personal aircraft.

Due to the dark and cold water, it is still fairly well preserved, though the canvas over the tube frame light structure is gradually deteriorating.

A proposal has been made to raise the wreckage, but local divers are strongly opposed because of its status as a war grave, and the risks of damaging it.
