The Halberstadt B-types of the Halberstädter Flugzeugwerke were two-seat unarmed reconnaissance/training aircraft of the German Air Force in the First World War.
In 1914, Halberstadt developed a biplane with the Oberursel U.0 rotary engine with 80 hp, which was referred to as Halberstadt B.I and was given the factory name A15. The Halberstadt B.II (B15) was built with a Mercedes D.I inline engine with 105 hp and in 1915 the Halberstadt B.III was produced with the slightly stronger Mercedes D.II (120 hp).
Halberstadt B.II was used as the base for the first armed two-seater, the Halberstadt CL.II.
The B.I was used as a trainer aircraft, while the B.II and B.III briefly served as reconnaissance aircraft, but were later also used for pilot training.
