Heeresversuchsanstalt Peenemünde
By January 18, 1945, rumors of nearby Soviet tanks resulted in Erich Regener's organization being sent from Peenemünde before the A-4 instrument package had been finished. The "Regener-Tonne" parachute was tested at Test Stand VII of the Peenemünde Army Research Center and a mock-up was launched in January 1945.
