Junkers CL.I
Junkers · Germany · first flew 1918 · fighter
The Junkers CL.I was a pioneering all-metal two-seat close-support and escort aircraft of the First World War, distinguished by its low-wing monoplane configuration at a time when biplanes dominated. Its corrugated Duralumin structure reflected Hugo Junkers' radical construction philosophy.
Recognition (WEFT)
| W — Wings | Low-mounted, straight |
|---|---|
| E — Engines | 1 × piston, nose-mounted |
| F — Fuselage | 7.9 m fuselage |
| T — Tail | Conventional |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- All-metal corrugated Duralumin skin
- Low-wing monoplane in WWI biplane era
- Two-seat ground-attack and escort fighter
Look for the distinctive corrugated metal skin and low-wing monoplane layout unique among WWI German types; the two-seat tandem cockpit sits well aft under a high-set parasol-style wing structure.

History
Developed in 1918, the CL.I emerged too late to see extensive combat before the Armistice in November 1918, with only a handful reaching operational units. It nevertheless proved the viability of all-metal cantilever monoplane construction for military aviation. The design directly influenced Junkers' interwar commercial aircraft.
Variants
The J 8 was the factory designation of the prototype and development aircraft; the slightly modified production version was the J 10, built by the Junkers-Fokker joint venture. Three were built as CLS.I floatplanes (J 11). After the war one or two CL.Is were converted for commercial use with the rear cockpit enclosed.
Where you'll see it
Used very briefly by German aviation units in the final weeks of WWI, the CL.I is historically significant primarily as a technical milestone rather than a combat veteran.
