Service Year: 1917
Type: Floatplane Biplane Fighter Aircraft
National Origin: Imperial Germany
Manufacturer(s): Luft Torpedo Gesellschaft (LTG) - Imperial Germany
Total Units Built: 6

Luft Torpedo Gesellschaft (LTG) of Germany delivered for the German Navy of World War 1 (1914-1918) the FD.1 Floatplane Fighter. This particular floatplane was developed to a specific Navy requirement and a total of six were ultimately delivered during the fighting, deliveries spanning from early-1917 until early-1918. At least one example was used for testing various weight load. Power for the aircraft was served through a single Benz Bz III series engine developing 150 horsepower and driving a two-bladed propeller at the nose.

The aircraft exhibited a traditional biplane wing arrangement consistent with the period. The fuselage was as streamlined as possible which included qualities like an enlarged spinner for the nose and slab sides for the body. A long vertical fin was set at the tail as were low horizontal planes. The aircraft carried a sole operator and he was seated aft of the upper wing element - a section of the wing cut-out for the operator's view. Single bays were used along the biplane wing configuration. Twin floats made up the undercarriage with a strut network used to brace the aircraft during landing and take-off.

As a fighter, the FD.1 carried 2 x 7.92mm machine guns in the upper forward fuselage, synchronized to fire through the spinning propeller blades by way of interrupter gear.

The aircraft was also known under the SD.1 designation.
