History

Designed at the Friedrichshafen works on Lake Constance, the D.I emerged late in the war when Germany needed competitive single-seat fighters. It entered the second D-type competition of 1918 alongside designs from Fokker, Albatros, and Pfalz, but more capable aircraft were already available. The aircraft remained a prototype only.

Variants

No production variants were developed; the D.I existed only as a prototype and evaluation aircraft.

Where you'll see it

The D.I saw no operational service, being eliminated during comparative trials against superior contemporaries.
