Heinkel He 60-D

Heinkel He 60-D The Heinkel He 60 was a German single-engined biplane reconnaissance seaplane designed to be catapulted from Kriegsmarine (German navy) warships of the 1930s. The Heinkel He 60 was designed by Heinkel engineer Reinhold Mewes, the designer of the He 59. The resulting design was a single-engined biplane of mixed wood and metal construction with fabric covering. Its single bay wings were of equal-span and had significant stagger The first prototype flew early in 1933 and proved to be underpowered with its 492 kW (660 hp) BMW VI engine. The second prototype had a more powerful version of the BMW engine, but this only marginally improved its performance and was unreliable, so production aircraft reverted to the original engine.
