at Neuhardenberg (a large field about 70 kilometres east of Berlin, listed as a reserve airfield in the event of war). On 3 June 1937 the Heinkel He 112 was flown by test pilot Erich Warsitz, propelled by rocket power alone, despite the wheels-up landing and having the fuselage on fire due to an unpredicted area of low aerodynamic pressure drawing alcohol fumes back into the airframe which then ignited. In May 1937, Dornberger, and most of his staff, moved to Peenemünde on the island of Usedom on the Baltic coast which offered much greater space and secrecy. Dr. Thiel and his staff followed in the summer of 1940. Test Stand VI at Pennemünde was an exact replica to Kummersdorf's large test stand. 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. After 1938 Kummersdorf was used for nuclear research. Armored fighting vehicle history Kummersdorf was also the location for the analyses, studies and testing of various German-captured Allied tanks and armoured fighting vehicles (AFVs). Many tanks from all combat-fronts, from North Africa to the Eastern Front, were tested there, with American tanks being multiple variant-models of the M4 Sherman tank, the M3 Lee, the M10 tank destroyer, amongst several others, and Soviet tanks consisting of the T-34 (the mainstay of Soviet armoured forces) and the T-28 medium tanks, the SU-series of self-propelled artillery/guns (such as the SU-85) and the IS-2 heavy tank, just to list a few. There were also British tanks there, including a Churchill tank fitted with a Y-shaped exhaust outlet (an early variant-model of the Churchill) for deep-wading and amphibious operations which was used at the Dieppe Raid, along with many Matilda I and Matilda II infantry tanks (with the former being largely seized following the evacuation of Allied troops at Dunkirk and the latter from both Dunkirk as well as in North Africa). There were also many French tanks there as well, such as the Char B1 heavy tank. Also, an Italian Carro Armato P40 heavy tank was present at Kummersdorf. The Wehrmacht also tested new German tanks there, including the VK 4501 (P) (the losing Porsche-hulled competitor for the Tiger I
