Farman F.51 Flying Boat
This aircraft was designed to meet the same "high seas" flying boat requirement as the Farman three-engine flying boat (see below). It was built in 1918 and featured a hull designed by Blanchard. It was powered by two 275-hp Lorraine-Dietrich 8Bd engines and carried a crew of three. The aircraft was tested at the Saint Raphael naval air station. However, the Armistice resulted in the French navy's decision not to purchase any additional flying boats in the "high seas" category.
Although the Farman F.51s were not adopted by the French Aviation Maritime, two were purchased by the Brazilian naval air service. These aircraft, given serials 36 and 37, were not uncrated until August 1923; in fact, only aircraft 37 was ever fully assembled.

Farman High Seas Flying Boat
The French naval requirement for a "high seas" flying boat in the same class as the British Felixstowe flying boats specified many ambitious goals. The aircraft was to have a crew of four, a wireless, a 75-min cannon with 35 rounds, four I (120-kg) bombs, an endurance of eight hours, a range of 300 kilometers, a maximum speed of 140 km/h, and be able to climb to 2,000 meters in 25 minutes. Apparently the Farman firm submitted two different aircraft to meet this requirement.
The three-engine flying boat appears to have been based on Besson's trimotor flying boat of 1918. In 1918 the Farman firm had built Levy flying boats under license and had considerable experience with flying boat construction in general and the Levy-Besson fuselage design in particular. While the hull of Farman's aircraft was similar to Besson's designs, the wings were completely different. Whereas Besson favored a triplane layout, Farman's aircraft was a biplane. Also, the Farman design used three Panhard engines of 330-hp; Besson's aircraft had three 350-hp Lorraine engines. There was a crew of four, with two pilots and an observer sealed in the nose and a second observer a separate cockpit behind the wings.
The aircraft was tested at the Saint Raphael naval air station. It was capable of carrying up to 500 kg of bombs to attack enemy shipping and submarines.
