The Junkers J 3 was a pioneering German all-metal cantilever monoplane of World War I, demonstrating Hugo Junkers' vision of strut-free thick-wing construction. It was an experimental aircraft rather than a production type.

History

First flown in 1917, the J 3 advanced the corrugated-duralumin structural approach introduced with the J 1. It helped establish the low-wing cantilever monoplane as a viable configuration and directly influenced subsequent Junkers commercial and military designs.

Variants

The J 3 was a one-off experimental machine; the related J 4 and J 7 followed the same philosophy in different roles.

Where you'll see it

Never entered service; used solely for experimental evaluation by Junkers and German military assessors.
