2007 Junkers D.I (gamyklinis pavadinimas J 9) buvo monoplaninis naikintuvas, pagamintas Vokietijoje I pasaulinio karo pabaigoje, reikšmingas tam, kad taptų pirmuoju metaliniu naikintuvu, pradėjusiu tarnybą. Prototipas, privati "Junkers" įmonė, pavadinta "J 7", pirmą kartą skrido 1917 m. rugsėjo 17 d., bandymų metu išgyvendama beveik pusšimtį detalių pakeitimų. Kai kitų metų pradžioje jis buvo pademonstruotas "Idflieg", jis pasirodė pakankamai įspūdingas, kad būtų užsakyti trys papildomi orlaiviai bandymams. "Junkers" atlikti pakeitimai buvo pakankamai reikšmingi, kad įmonė pervadintų kitą pavyzdį J 9, kuris buvo pateiktas "Idflieg", o ne trims užsakytiems J 7.

General Characteristics
The Junkers J 9 (military designation D.I) was a German monoplane fighter aircraft produced late in World War I, notable for being the world’s first all-metal fighter to enter military service. Designed by Hugo Junkers, the aircraft featured a revolutionary cantilever wing and fuselage entirely covered in corrugated duralumin (an aluminum alloy). This construction method made the aircraft exceptionally durable and easy to maintain compared to conventional wood-and-fabric aircraft, though early models were criticized for low maneuverability. Only a small number of J 9s were delivered before the Armistice, primarily used by the Imperial German Navy for coastal defense and later by paramilitary Freikorps units after the war.

Powerplant and Performance
- Engine: 1 x BMW IIIa water-cooled 6-cylinder inline piston engine (Later production models and prototypes were also fitted with Mercedes D.IIIa/aü engines).
- Power Output: 138 kW (185 hp) (BMW IIIa).
- Maximum Speed: 176 km/h (109 mph) (with BMW IIIa).
- Service Ceiling: 6,000 m (19,700 ft).
- Endurance: 1.5 hours.
- Design Note: Its all-metal, low-wing monoplane design was extremely advanced for its time, predating similar designs by over a decade.
Ginkluotės
- Armament: 2 x 7.92 mm LMG 08/15 Spandau machine guns, fixed and synchronized to fire forward through the propeller arc.
- Operational Note: Despite being an advanced design, many German pilots preferred the maneuverability and climb rate of contemporary biplanes, such as the Fokker D.VII, for traditional aerial combat. The J 9 was deemed better suited for specialist roles like naval patrol or balloon attack.
