I think it's a wire-controlled glide torpedo developed by Siemens-Schuckert during WWI and launched from under the belly of an L35 Zeppelin as depicted below. I guess it's one of the earlier versions from about 1916/17, but I have no clue which one.
Absolutely right.
It's the early 1917 version of the Siemens-Schuckert aerial torpedo, controlled via a thin wire from it's launching aircraft (Zeppelin during trials, intended carrier aircraft was the Siemens-Schuckert R VIII). The picture was taken in
Jüterbog Summer 1917.
The carrier is "L 35" (LZ 80), an "R" class "Super Zeppelin" with 19 gas cells.
The picture was taken from the book
"German Guided Missiles" by Heinz J. Nowarra (Translation by James C. Cable), Schiffer Military/Aviation History Atglen, PA - (C) 1993 Schiffer Publishing Ltd. - ISBN 0-88740-475-8
