According to some manuscripts appeared very simple sketches of a kind of "torpedo" propelled by rockets due to the Syrian Al Hassan er-Rammah of 1280 AD.

-It is reproduced in later books and finally rebuilt as a model in 1976 for the NASM by George Marsden Design.

"Hassan's air-torpedo model"

-It is not known if it was ever built. Loaded with flammable material and propelled by two adjacent gunpowder rockets.

-Launched against enemy ships, it would burn them down and destroy them. It could have been made with simple materials such as wood, brass, etc. The rear feathers served to stabilize the ingenuity.

-Interestingly, during WWII the Germans made a small missile conceived by Dr. Kramer and built by Ruhrsthal. This missile had a huge resemblance of design concept.

-It was a wire-guided anti-tank missile, and it had several versions based on the X-7 main concept.

-They used model 109-506 Wasag (see) solid fuel engines and two stages.

-It used Dyglicol as fuel and delivered 150 lbf of thrust. This was the "Steinbock". Other versions were the "Pfeifenkopf" and the "Pinsel" with electro-optical guidance systems.

-We show a couple of these X-7 missiles and leave the possibility of Kramer's inspiration from Hassan's torpedo to the reader's criteria.

-On occasion the name of Hassan Er-Rammah has been written Al-Rammah. (see in A-Z)
