The Halberstadt CL.IV was a German ground attack aircraft of the First World War.

Design and development

Karl Thies, chief designer of the Halberstädter Flugzeugwerke, G.m.b.H., designed the CL.IV as a replacement for the Halberstadt CL.II. As the CL.II had proven to be particularly effective in the ground support role, the focus of an improved version was to create a specific ground attack aircraft.

The new CL.IV featured a shorter, strengthened fuselage and a horizontal stabilizer of greater span and higher aspect ratio than that of the CL.II. These changes, along with a one-piece, horn-balanced elevator, gave the CL.IV much greater maneuverability than its predecessor. After tests were completed of the prototype in April 1918, at least 450 were ordered from Halberstadt, and an additional 250 aircraft from a subcontractor, LFG (Roland).

Operational history

The Halberstadt CL.IV was one of the most effective ground attack aircraft of the First World War, relying on its good maneuverability to avoid ground fire. It appeared on the Western Front towards the end of the German offensives in 1918. Flights of four to six aircraft flew close support missions, at an altitude of less than one hundred feet, suppressing enemy infantry and artillery fire just ahead of the advancing German troops. After these late German offensives stalled, Halberstadt CL.IVs were used to disrupt advancing Allied offensives by striking at enemy troop assembly points and night sorties were also made against Allied airfields.

Towards the end of the war, on bright, moonlit nights, CL.IV squadrons attempted to intercept and destroy Allied bombers as they returned from their missions.
