The Friedrichshafen FF.29 was a German lightweight two-seat floatplane of the 1910s produced by Flugzeugbau Friedrichshafen.

Development and design[edit]

The FF.29 was designed as a lightweight floatplane, a biplane powered by a Mercedes D.II inline piston engine. Five FF.29s were built at the Orlogsværftet Flyvemaskineværksted in Denmark, designated Orlogsværftet HB.I

Operational history[edit]

The FF.29 entered service with the German Imperial Navy in November 1914, it was used for coastal patrol and reconnaissance and had the ability to carry a small load of bombs. On 24 December 1914 an FF.29 was the first aircraft to drop a bomb on British soil, a single bomb landed in the garden of a house in Leyburn Road, Dover. There were no injuries and little damage beyond a crater in the lawn and smashed windows. On 15 January 1915 a FF.29 was the first plane to be launched from a submarine, the SM U-12.
