Junkers Ju 87 late 1934. It was to have been completed in April 1935, but, due to the inadequate strength of the airframe, construction took until October 1935. The mostly complete Ju 87 V1 W.Nr. 4921 (less non-essential parts) took off for its maiden flight on 17 September 1935. The aircraft was later given the registration D-UBYR.

The result followed closely the aerodynamic design of the Ju 252 but was an entirely new aircraft. The wing
