The Projekt Schwimmweste (swim vest) was conceived to allow a modified V2 rocket to reach the North American continent. The missile was to be transported to a short distance off the shore in a submersible container (codenamed Prüfstand XII) towed by the also innovative Type XXI submarine. The V2 container has a trim system to bring it to vertical for launch.
This project only materialised in 4 or 5 containers -only one according to other sources- built and tested by the Vulkanwerft at Stettin. By early-1945 the promising prospects of the startling A9/A10 two-stage rocket were more “realistic”.
