Grosskampfflugboot G

At the turn of the years 1914 and 1915 began to build in the Pulském arsenal (Seearsenal Pola) large flying boats under the designation Grosskampfflugboot (Large seaplane), abbreviated Flugboot G (Seaplane type G or how at the time, the English called Hydroavion G). The whole project šéfoval Linienschiffsleutnant Maschinenbauingenieur 2. Klasse der Reserve Josef Mickl. Ing Josef Mickl was also a marine pilot. Project třímotorového the aircraft was at that time a whopping.

According to the original design Depicted on the Joseph Mickla, submitted and approved admiralitou, was to be built třímotorový flying boat, carrying two of the torpedo or 800 kg of bombs and was preparing to take to arm hydroavion a cannon of the caliber of 66 mm. The cannon for this aircraft is developed and produced in the pilsen škoda auto. It was a cannon caliber 66 mm (d/20. Cannon armament was about 400 kg lighter than the torpedoes and bombs, but the recoil could destroy the skeleton of the hydroavionu. And also the caliber of 66 mm and his penetrator grenades weighing 5 kg could not threaten the more a ship than a torpedo boat. One could, with well secvičenou the crew of the aircraft easily maneuver and destroy their cannons or machine guns. Already before the completion of the prototype in the summer of 1915, it was decided to refrain from arming hydroavionu torpédy and use it to destroy enemy ships, only shooting 66 mm cannon. The first prototype under the designation G-1 was finished in the autumn of 1915.

The prototype with the designation G-1 in test flight 23. November 1915 crashing. Before landing with the Hydroavionu G 1 ripped off the top wing and hydroavion crashed into the Pulského port. The main pilot, former commander of naval air force, Linienschiffsleutnant Hugo Ockermüller died, the second pilot Gottfried Freiherr von Banfield and the mechanic Havelka were severely injured.

Despite this disaster, the construction of the prototypes continued. Used motors to drive the hydroavionu with take-off weight without the arms of over of 4000 kg was not enough. Hydroavion reached a maximum speed of 110 km/h and to a maximum of 600 m was 45 minutes. In 1916, namontovaly more powerful the propulsion unit of Daimler, but even this may significantly help (more powerful engines in 1916 in Germany and Austria did not exist). Hydroavion still had the bad flight characteristics and there was also poor strength of the airframe in flight weight of over 4 tonnes. The materials used and the technology of that time, unfortunately, more could not.

The second disaster has occurred after a year of testing other prototypes. Day 6. November 1916 disaster befell the prototype Hydroavion G 5 and the entire crew. After the ceremony of the start of the Pulské of the bay hydroavion crashed over Fažanským the channel and landed on the coast. In the ruins of the hydroavionu died Linienschiffsleutnant Gustav Klasing, Fregattenleutnant Hely Nicora, Fregattenleutnant Stanislav the ka'ba (*1893, Stanislav the ka'ba was Czech, he joined the navy in 1912 as a naval aspirant).

Only after the project has been velkohydroavionu stopped and the other 8 prototypes have been repealed.

In the number of constructed prototypes with resources diverge, according to one was built 9 prototypes, according to the other 10 or up to 12 pieces.
