X4 Chronology

1945 January 27 - . Launch Vehicle: Schmetterling; Wasserfall; X4.
  • First meeting of Arbeitstab Dornberger in Berlin - . Nation: Germany. Related Persons: Dornberger. The group's first priority was to evalute the prospects for rapid development of an effective surface-to-air missile to combat the incessant Allied bombing raids. It had to be beam-riding instead of optically guided, in order to be effective at night and in bad weather. The group found there was no single 'wonder weapon' that would end the war in a few months. But Kammler still believed the Reich still could hold out for six months, enough time to develop and deploy a new weapon. Dornberger's team disagreed, but they had to try nevertheless. Therefore the Schmetterling, Wasserfall, and X4 missiles went into simultaneous final development and production. But realistically none of them could be mature enough to be sent to the front until early 1946. If the Reich could hold out that long, then it was possible it could slowly win back territory.
