Friedrichshafen FF.49 was a German, two-seat, single-engine float-plane designed by Flugzeugbau Friedrichshafen in 1917.
Grigorovich M-16 was a successful Russian World War I-era biplane flying boat of the Farman type, developed from the M-9 by Grigorovich. Somewhat larger than the M-9, the M-16 was a version especially intended for winter operations, with better aerodynamic qualities.

The Friedrichshafen FF.34 was a German biplane floatplane of the 1910s produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.40 was a German three-seat floatplane of the 1910s produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.64 was a German two-seat biplane floatplane of the 1910s produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.43 was a German single-seat floatplane fighter of the 1910s produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.48 was a German two-seat floatplane fighter of the 1910s produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.53 was a German torpedo-carrying biplane floatplane of the 1910s produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.60 was a German experimental floatplane produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.35 was a seaplane torpedo bomber built in Germany during World War I. Similar in general design to the Friedrichshafen G.I, it was a conventional four-bay biplane with unstaggered, unequal-span wings. The horizontal stabiliser was mounted halfway up the tail fin, and the undercarriage consisted of two widely spaced pontoons. The sole FF.35 was delivered to the German Navy for testing in May 1916 and was given the serial number 300. Although no further examples were built, the FF.35 formed the basis for the successful FF.41.
The Friedrichshafen FF.71 was a German biplane floatplane produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen D.I was a German single-seat fighter plane developed by the Flugzeugbau Friedrichshafen during the First World War. Two prototypes were flown in 1917, but it was judged inferior to the Albatros D.III then in production and no further production ensued.
The Friedrichshafen FF.1 was a German experimental floatplane built in 1912. It was the first aircraft designed and built by the newly established Flugzeugbau Friedrichshafen. Only one prototype was constructed and it set a world record for endurance in 1913 before crashing in early 1914.
The Friedrichshafen FF.2 was a floatplane built in Germany in 1913. It was derived from a design by the Swiss pilot and designer René Grandjean. Only one aircraft was built before the design was reworked into the Friedrichshafen FF.4 the following year.
The Friedrichshafen FF.17 was an experimental floatplane built in Germany in 1914. Originally designed and flown with a single main float and two outriggers as the FF.17, it was later modified as the FF.17b with two floats.
The Friedrichshafen FF.63 was a German experimental floatplane produced by Flugzeugbau Friedrichshafen.
The Friedrichshafen FF.67 was a German experimental floatplane produced by Flugzeugbau Friedrichshafen.
