The Spijker V.3, sometimes anglicized to Spyker V.3 or Spyker-Trompenburg V.3, was a Dutch single-engine, single-seat biplane fighter, designed and built just before the end of World War I.
It was a single-bay biplane, with one pair of parallel interplane struts on each side and with a central cabane between fuselage and the upper wing.
It was powered by a 97 kW (130 hp) Spijker-Clerget rotary engine, driving a two-blade propeller and enclosed by a full cowling.
The conventional undercarriage was fixed, with mainwheels on a divided axle supported at each end on wooden V-form struts.
The tailplane was mounted near the top of the fuselage, carrying elevators divided to allow for rudder movement, as the latter extended down to the keel.
