The Hannover CL.V was a ground attack aircraft built in Germany during World War I, which formed the basis for a sport aircraft following the war. Derived from the Hannover CL.II, the CL.V shared the same basic conventional biplane configuration and incorporated the overhanging, aerodynamically-balanced ailerons developed for the Hannover CL.III. The characteristic biplane tail used on earlier Hannover CL-class machines was dispensed with, and a conventional empennage was fitted to the prototype, although production machines reverted to the earlier design. The Idflieg placed an order for 100 aircraft, but only 46 of these were built before the end of the war, and none of them had been put into service by that time. Hannover built another 62 examples after the Armistice,
In its civil configuration, designated F.6, the aircraft dispensed entirely with the rear cockpit, and once again used the monoplane tail unit that had been fitted to the CL.V prototype.
In 1923, another 14 CL.Vs were produced for the Norwegian army air service by Kjeller. These were known as the Kjeller FF.7 Hauk ("Hawk") and remained in service until 1929.
