-It is the Messerschmitt missile "Enzian" from which about 60 were built, being tested about 38 around 1944.

-It is a liquid fuel rocket engine. We see that the tanks are occupying a big part of the fuselage. The combustion chamber and nozzle are clearly seen in the figure.

-The Enzian IV and V had the Konrad DVK engines, the former one used Visol and SV-Stoff, and delivered a thrust of 2,000 lbs.

-The latter used Br-Stoff (Benzina) and SV-Stoff giving a thrust of 2,500 lbs.

-Around the fuselage they had solid fuel engines as aid for launching from the ground. (boosters or RATO), These engines were possibly Schmidding.

-There also were nitrogen bottles for pressurizing the propellant tanks.

-Another Konrad engine was used on the Rheintochter R3. It used Visol and SV-Stoff, and it delivered 2180 lbs. of push.

-The Enzian I and III had Walter 109-502 engines with less power, 1500 lbs.
