It had a lengthened nose for the photographic equipment and it was powered by two 960 hp Daimler-Benz DB 600 Aa engines. The type was not ordered for production, but D-AOFI received the code "CE+BX" and was used for towing the Me 163 A, initially at the companies airfield at Augsburg, later at the Peenemünde-West Luftwaffe test center.
