Despite Todt's death, the OT continued to exist as an engineering organisation and was given more assignments. At the beginning of 1943, in addition to its continuing work on the Atlantic Wall, the organization also undertook the construction of launch platforms in northern France for the V-1 flying bomb and V-2 rocket. During the summer of that year, the German war efforts became increasingly defensive, and the organization was further directed to construct air-raid shelters, repair bombed buildings in German urban areas, and construct underground refineries and armaments factories, also termed Project Riese.
