The Hansa-Brandenburg G.I was a German bomber built by the Hansa and Brandenburg Airplane Works built exclusively for the Luftwaffe of Austria-Hungary.
Development and construction:
The company Hansa and Brandenburgische Flugzeug Werke originated from the merger of the Brandenburgische Flugzeugwerke GmbH and the Hansa-Flugzeug Werke in 1914. Already from the beginning the aviation pioneers Igo Etrich and Ernst Heinkel, who already had both experiences in aircraft construction, were involved.
Under their leadership, at the beginning of the war, at first unarmed, later armed reconnaissance aircraft were built for the German and for the Austro-Hungarian army. At the end of 1914, when the German army command set the requirements for a bomber to replace the zeppelins, the two designers also began to develop a corresponding aircraft.
The first two prototypes were called ZM I and ZM II, but could not meet the requirements. Only the Hansa-Brandenburg GF, which was later renamed Hansa-Brandenburg G.I, was able to convince.
Two 160 hp Austro-Daimler engines were installed. The pilot and the stern shooter shared a pulpit while the bowman received a separate pulpit. Unlike other aircraft, the engines were not mounted on one of the wings but sat with steel braces fastened in between. This had the disadvantage that the vibrations made themselves felt strongly.
With the entry of Italy into the war on the part of the Allies and their bombardment at the front, the military leadership of Austria-Hungary decided to buy bombers. Initially, two Hansa-Brandenburg G.I aircraft were ordered. However, the damage during transport and the subsequent legal dispute over the compensation, delayed their use at the front considerably. After this was settled, some aircraft were rebuilt under license and ordered more aircraft in early 1917.
Use in the First World War:
After some aviation companies of the Austro-Hungarian Air Force were equipped with the bombers, it was already clear that these aircraft were already outdated and the German Gotha G.IV bomber were much more modern.
Overall, the Hansa-Brandenburg G.I aircraft were deployed for only three months at the front, flying only one attack. Afterwards, these were only used for training.
