The '''Lloyd C.II''' and its derivatives, the '''C.III''' and '''C.IV''' were reconnaissance aircraft produced in Austria-Hungary during the First World War.<ref name="Jane's">Taylor 1989, 581</ref> They were based on the Lloyd company's pre-war C.I design, and like it, were conventional biplanes with swept-back wings.

==Design and development== After the outbreak of World War I, the original aircraft was refined somewhat by Lloyd designers Wizina and von Melczer,<ref name="Gunston">Gunston 2003, 184</ref> featuring a reduced wingspan and wing area but increased weight.<ref name="Grosz">Grosz 2002</ref> An 8&nbsp;mm Schwarzlose machine gun was added on a semi-circular mount for an observer.<ref name="Murphy">Murphy 2005, 108</ref>

Beginning in 1915, one hundred examples of this type were built – fifty by Lloyd at their plant in Aszód, and another fifty by WKF in Vienna.

Apart from their service with the Austro-Hungarian flying service, ten C.IIs saw service with Poland. These were captured in Malopolska in November 1918 and were used as trainers until being withdrawn from service in 1920.

thumb|A C.III shot down in Romania|class=notpageimage The '''C.III''' was almost identical except for the use of a 120&nbsp;kW (160&nbsp;hp) Austro-Daimler engine, which increased the top speed to 133&nbsp;km/h (83&nbsp;mph).<ref name="Grosz" /> Production again was by both Lloyd and WKF, with total production amounting to 50-60 machines.

The '''C.IV''' also used the Austro-Daimler engine, and small batches were produced by both Lloyd and WKF.<ref name="Grosz" />

==Variants== * '''C.II''' with Heiro engine and 14.00 m wingspan (100 built) * '''C.III''' with Austro-Daimler engine and 14.00 m wingspan (8 or 16 built by Lloyd, 43 by WKF) * '''C.IV''' with Austro-Daimler engine produced by Lloyd with 14.52 m (47&nbsp;ft 8 in) wingspan (47 built, plus one converted)
