Hitler visited Kummersdorf West in March 1939, accompanied by Walther von Brauchitsch, witnessing the test firing of the 650 and 2200 pound thrust rocket motors, and viewed components of the A-3 and A-5. He also enquired how long it would take to develop the A-4. Hitler was skeptical of the rocket's potential.
