The DFW Mars was an early German military utility aircraft built in 1913 and was the first original design manufactured by 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) engine. Examples of the monoplane built 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 engine. The wings of both the monoplane and biplane versions featured prominent sweepback.
