Pitre Error?
In 1943 there was a crisis in rocket development. Numerous projects were in their early stages, and the design teams encountered the widest variety of problems. At that time the following missiles were under production: Enzian and Rheintochter (subsonic, later supersonic), Schmetterling (subsonic) and Wasserfall (supersonic). The rockets had different engines and needed different fuels. Although the RLM and Speer’s Armament Office could not agree on a uniform rocket fuel, it was agreed that there should be a general increase in the production of special fuels despite the lack of industrial capacity. Getting development going was the important thing.
Feuerlilie F25 and F55
In 1940, the LFA Hermann Goringhtg^n design work on a long-range, remote- controlled rocket, the F 25 Feuerlilie. At first 25 were tested by DFS and the Reichspost Research Office. The first F 25 arrived at the Leba test site on the Baltic in mid-July 1943. By mid-summer 1944 at least four had been fired. On 25 January 1943 the Ardelt company of Breslau (Wroclaw) received an official contract to build five improved experimental type F 55 rockets at RM.20,000
each. Unexpected technical difficulties resulted in the first start of F 55 A-l being delayed until 12 May 1944 when it rose 7.5 kilometres in 69 seconds. From 22 November 1944 the RLM Technical Office continued to reduce the number required as other rockets gained in favour.
