There were more tests on the military training area Doeberitz in Berlin and at Lake Starnberg. The best results were obtained with 60% liquid oxygen and 40% coal dust. The destruction radius in Döberitz was reportedly 600 meters, and 4 to 4.5 kilometres for the improved 25 to 50-kilogram bomb over Lake Starnberg. At the end of the war preparations were under way for the production of larger bombs with liquid oxygen in Nordhausen.
