The **DFW Mars** was an early German military [utility aircraft](/source/Utility_aircraft) built in 1913, the first original design manufactured by [Deutsche Flugzeug-Werke](/source/Deutsche_Flugzeug-Werke) (DFW). The aircraft was produced in both monoplane and biplane versions, which shared a common fuselage and empennage. The monoplane version featured wings that were wire-braced to a kingpost on the forward fuselage, and was powered by a 71 kW (90 hp) [NAG](/source/Nationale_Automobil_Gesellschaft) engine. Some of the monoplane used as dedicated trainer aircraft also incorporated a reinforcing truss beneath the wings. The biplane had conventional three-bay wings of unequal span and was powered by a 75 kW (100 hp) [Mercedes](/source/Mercedes_(car)) engine. The wings of both the monoplane and biplane versions featured prominent sweepback.

Mars aircraft were distinguished in pre-war passenger-carrying feats and reliability trials. They were purchased by both the German military and the [British Admiralty](/source/British_Admiralty), which bought an example for the [Royal Naval Air Service](/source/Royal_Naval_Air_Service). Turkish Mars aircraft were flown in the [First](/source/First_Balkan_War) and [Second Balkan Wars](/source/Second_Balkan_War) in 1912–1913. This type is believed to be the first German-built aircraft utilized for active military service.
