ザ ユンカースD.I ●(工場指定J9)は第一次世界大戦後半にドイツで生産された単葉戦闘機で、初の全金属製戦闘機として就航した大きな意味を持つ。ジャンカーズのJ 7という名前のプライベートベンチャーであるプロトタイプは、1917年9月17日に初飛行し、テスト中に設計の半ダース近くの詳細な変更を経た。それは翌年の早い時期にIdfliegに実証されたとき、それは試験のための3つの追加の航空機のための順序をもたらすのに十分な印象的であることが判明しました。ユンカースが行った変更は、会社が注文した3つのJ 7の代わりにIdfliegに供給された次の例J 9の名前を変更するのに十分重要でした。

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.
武装
- 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.
