development
During the year 1913, the acquired Imperial Navy in response to a May 3 of Kaiser Wilhelm II. Issued available establishing a first naval aviation department for lack of local alternatives a British swimmer aircraft type Avro 503 and tested it with the Marine Mark D-12 when equipped their autumn maneuvers of 1913 on its seaworthiness . Compared to three German constructions from Albatros and AGO, which also took part , it performed much better, so that at the beginning of 1914 the naval management commissioned AGO GmbH to develop a similar model. But neither of which with a Oberursel - rotary engine equipped Avro copy was achieved in January 1914 in another set to float and become outdated AGO Gitte fuselage plane Kiel-Holtenau convince conducted presentation so that the purchase of five aircraft in February albatross and Friedrichshafen was transferred. Delivery of the two competing models began at the end of April 1914, but while the Albatros design also did not meet the requirements, the five FF 19s were taken over by the Navy by May 18 and completed the tests carried out from May 7 to June 18 without hesitation. They were put into service with naval numbers 25 to 29; Another specimen had been used on May 2 for breaking tests, whereby the wing, which was only covered on one side, only broke under 7.02 times the load. The FF 19 was thus the first model that met the requirements of the Navy for a seaplane of the First World War, which included the greatest possible seaworthiness, at least four hours of flight time and nautical equipment including signaling devices and a crew of two. Among other things, it was also used as an on-board aircraft . The successful construction resulted in a follow-up order for ten more aircraft, which were delivered by November 1914 with the naval numbers 76 to 85. With an FF 19, tests with wireless radio were carried out for the first time in Germany with a seaplane . The successor was the FF 29 , which was equipped with a more powerful drive .
