The Halberstadt CL.II was a German two-seat escort fighter/ground attack aircraft of World War I. It served in large numbers with the German Luftstreitkräfte (Imperial German Army Air Service) in 1917-18.
Early in 1917, Idflieg, the German Army Inspectorate of Flying Troops, developed a requirement for a new type of two-seat aircraft, smaller than the existing C-type aircraft. This type, to be known as CL-type (Light C type) aircraft, were to be used to equip Schutzstaffeln (Protection flights) to escort reconnaissance aircraft. To meet this requirement, Halberstadt developed an aircraft based on its earlier, unsuccessful Halberstadt D.IV single-seat fighter. Originally designated the Halberstadt C.II, it was redesignated the Halberstadt CL.II when the CL designation was applied.
The CL.II was a single-engined biplane, with an all-wooden structure. The fuselage was covered with thin plywood panelling and housed the crew of two in a single cockpit, with the observer's 7.92 mm (.312 in) machine gun being mounted on an elevated gun ring, giving a good field of fire, allowing downwards fire at targets on the ground. A tray large enough to hold ten stick grenades was attached to the left side of the fuselage. The single-bay wings were fabric-covered, with a swept upper wing.
The aircraft had provisions for a wireless radio. When needed the radio and antenna could be installed in the observer's cockpit and a generator, that would also supply current for heated flight suits, could easily be installed. The generator was directly driven by a pulley on the engine and mounted on the left side with a tear drop shaped fairing covering it. With the generator removed, a flat panel would be fitted instead.
The CL.II passed its Typenprüfung (type-test) on 7 May 1917, which resulted in production orders being placed. Halberstadt built 700 CL.IIs by the time production shifted to the improved CL.IV in mid-1918. A further 200 CL.II aircraft were built in 1918 by the Bayerische Flugzeug-Werke (BFW).
