O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

L.V.G. 1915
   Exact designation of this L.V.G. machine is not certain. It was a derivative of the C I, completed as a single-seat torpedo machine for the Navy, and test flown in June 1915 by Flugmeister Herz. The complicated and robust undercarriage, with the "oversize" tyres, may be seen. The "object" in the carrying cradle is thought to be a mock-up rather than an actual torpedo. Engine, 200 h.p. Benz Bz IV.

LVG Torpedo Bomber Prototype

  The official designation for the LVG torpedo bomber prototype, if it actually had one, is uncertain. It has been called the 'LVG 1915' and has serial C.110 on the rudder, but its official designation is unknown. It was built to a German Navy requirement for a torpedo bomber and flight trials proved that it could carry the weight.
  Two different single-engine biplane designs were built to the naval requirement. One was the Albatros B.I S.69 and the other was this LVG. Both were three-bay biplanes. Although the Albatros prototype had a split under-carriage to enable the torpedo to be mounted at the aircraft's center of gravity, the rest of the airframe was visually similar to the three-bay Albatros B.I.
  In contrast, this large, three-bay biplane was derived from the two-bay LVG C.I but was significantly larger. Like the LVG C.I it was powered by a 150 hp Benz Bz.III engine. However, it was a single-seat aircraft with no gun armament; the observer/gunner and his gun were omitted to keep the aircraft as light as possible so it could carry the weight of a torpedo.
  A carrying rack was mounted under the fuselage to carry the torpedo and the under-carriage was a robust design with three struts on each side to withstand the loaded weight. Like the Albatros prototype, the under-carriage was split to enable the torpedo to be mounted at the center of gravity.
  The wing-span was significantly extended to provide more wing area to lift the heavy torpedo. Unlike the two-bay C.I with had ailerons on the upper wings only, the torpedo bomber had ailerons on all wings; an actuating rod connected the upper and lower ailerons on each side. The additional ailerons were required to maintain adequate roll control with the longer-span wings.
  Despite both Albatros and LVG prototypes demonstrating the ability to carry a torpedo, the Navy was not satisfied with the performance of either prototype - although the reasons were not specified. All subsequent WWI German torpedo bombers were two-engine biplane floatplanes, the single-engine landplane configuration being abandoned for carrying torpedoes. Performance of a 1915 biplane with torpedo was no doubt marginal.
