Fieseler Fi 98, Fi 167, Fi 256 and Fi 333

The Fieseler Fi 98 was a dive-bomber designed in response to the same RLM specification as the Henschel Hs 123, but that never progressed beyond the prototype stage.
The Fieseler Fi 167 was a ship-born two-seat torpedo bomber and reconnaissance aircraft designed to serve on the German aircraft carrier Graf Spee
The Fieseler Fi 256 was a five-seat version of the Fi 156 Storch, built in prototype form by Morane Saulnier in France
The Fieseler Fi 333 was a design for a transport aircraft that would have carried its cargo in detachable pods, allowing for a very rapid turn-around on the ground, and for the use of a number of different purpose-built pods to carry cargo, passenger, paratroops or fuel
