The Hansa-Brandenburg C.I, also known as Type LDD, was a 2-seater armed single-engine reconnaissance biplane designed by Ernst Heinkel, who worked at that time for the parent company in Germany. The C.I had similarities with the earlier B.I (Type FD, also designed by Heinkel), including inward-sloping interplane bracing struts. Like other early-war Austro-Hungarian reconnaissance aircraft, such as C-types of Lloyd or Lohner, the Type LDD had a communal cockpit for its crew. The C.I served in the Imperial and Royal Aviation Troops in visual- and photographic reconnaissance, artillery observation and light bombing duties from early spring 1916 to the end of World War I. The aircraft had good handling characteristics, and steady introduction of more powerful engines in successive production batches (see below) enabled the improvement of performance and thus the continuing front-line service.

Armament of the type consisted of a free-firing 8 mm (.315 in) Schwarzlose machine gun at the rear for the observer, and at least in some aircraft for the pilot there was also a similar fixed, non-synchronised forward-firing gun in a pod above the top wing. This latter weapon was replaced in later production examples by a synchronised 8 mm (.315 in) Schwarzlose gun on the port side of the fuselage. The normal bomb load for the C.I was 60 kg (130 lb), but some aircraft could carry one 80 kg (180 lb) and two 10 kg (20 lb) bombs.


Hansa-Brandenburg C.I were used first of all by Austro-Hungarian Imperial and Royal Aviation Troops for reconnaissance and bombing during World War I.

After the war, at least 33 machines were found in the Polish hands (some say 54)[1] and they were used during the Polish-Ukrainian War and Polish-Soviet War. The Hansa-Brandenburg C.I was the first aircraft of the Polish Air Force to complete a combat mission, on 5 November 1918, even before official acknowledgement of independence, during Lviv defence (flown by Stefan Bastyr)[2]

Aircraft Hansa-Brandenburg C.I was used in the Royal Air Force Yugoslavija since 1918. to 1930. year, at the school for training aircraft pilots. After military service are given Aeroclub, received the civil registration and used for training sports and reserve pilots.
