The Hannover CL.III was a two-seat, single-bay biplane built by the Hannoversche Waggonfabrik during the First World War for the Imperial German Army's (Deutsches Heer) Imperial German Air Service (Luftstreitkräfte). It was a multi-role aircraft derived from the CL.II, used to escort reconnaissance aircraft and as a ground-attack machine. It entered service early in 1918.

## Development

A crash-landed Hannover CL.III on the Western Front about September 1918

The CL.III (factory designation Typ 3b) was derived from the CL.II; its airframe was lightened and strengthened to improve performance and it was designed to use the water-cooled 160-horsepower (120 kW) Mercedes D.III straight-six engine rather than the 180-horsepower (130 kW) Argus As.III engine even though most D.III engines were reserved for fighters. In the event most aircraft used the readily available As.III engines. The Argus-engined variant was designated CL.IIIa. The aircraft had redesigned ailerons with aerodynamic balances that overhung the wingtips, a modification that provided greater manoeuvrability, especially at the low levels that it was expected to be operating at in its new ground-attack role as the Schutzstaffeln (escort squadrons) were reassigned as Schlachtstaffeln (battle squadrons). Like the other Hannover "light-C-class", or "CL" designated aircraft designed by Hermann Dorner, it included an unusual tail structure, with two horizontal stabilizers which allowed a wider field of fire for the observer.[1][2][3]

The CL.IIIb was an experimental aircraft that that was used to evaluate the 190-horsepower (140 kW) NAG C.III engine. After the war, a single CL.III was developed into the HaWa F.3, a limousine aircraft with seats for two passengers in an enclosed cabin where the gunner's cockpit had been.[4]
