This single-seat aircraft measures 5.7 meters long with an 8.3-meter wingspan, achieving 190 km\u002Fh with a 380-kilometer range. The modest incremental speed improvement over the D.III reflects the diminishing returns in piston-engine fighter optimization during war's final months. The D.IV's performance envelope remained typical of German rotary-engine fighters, emphasizing maneuverability and climb rate over speed.","Siemens-Schuckert D.IV — Late WWI fighter","German final-generation fighter (1918) with 190 km\u002Fh and 380 km range, single-seat combat aircraft."]
