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.
Specifications
- The Junkers CL.I has a length of 7.9 m (26 ft).
- It has a wingspan of 12.04 m (40 ft).

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 CL.I was essentially a single variant; a related Junkers J.I armoured ground-attack biplane shared the all-metal philosophy but was a distinct design.
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.
