(This does not mean, of course, that the over-all conclusions reached by the\njoint team are necessarily accepted.) Sources and evaluation of such material as did not\nappear in the joint effort are given here. It was felt, however, that little would be gained\nby repeating the voluminous references given in the study.\n3. 3 (b) (1)\nSince the joint report was issued, a\nsource has produced documentary evidence\nwhich indicates that German scientists in the Soviet Zone of Germany have recently done\nsome work on an antiaircraft rocket which combines features from a number of guided\nmissiles developed by the Germans during the war. Since it is believed this weapon has\nnever been discussed in previous intelligence reports, matters pertinent to its guidance\nand control will be treated in some detail on p. 95.\n1. A-4 (V-2) GUIDANCE AND CONTROL EQUIPMENT AVAILABLE IN NORDHAUSEN-\nBLEICHERODE AREA AT END OF ALLIED OCCUPATION\na. General\nAt the time the final German defeats were taking place, the center of nearly all\nV-2 rocket and of most other guided-missile activity in Germany was in the area around\nNordhausen (Harz) and neighboring Bleicherode. (See Chart I). This area was overrun\nby the United States First Army in April, 1945, and remained open for exploitation by the\nWestern Powers until the early part of July, when it was yielded to the USSR as part of\nthe agreed Soviet Zone of Occupation.\nManufacture of certain specific components and subassemblies of the V-2 had been\nscattered far and wide over much of Germany, but all the final assembly and most of the\nmanufacture of parts took place in the vicinity of Nordhausen. In addition, the facilities and\ntechnical personnel from Peenemuende were in the process of being moved to Bleicherode\nand vicinity.\nb. Mittelwerke, Niedersachswerfer\nThe only German production assembly plant for the V-2 was the Mittelwerke, lo-\ncated about five miles north of Nordhausen in the village of Niedersachswerfen, under a\nsteep limestone hill. (A relatively small portion of this plant was devoted to the assem-\nbly of V-1s.) The plant remained in production until it was captured by US forces. At\nthat time, all the subassembly and the main assembly lines were filled with assemblies\nin all stages of completion, but only two rockets were substantially complete, and those\nlacked the internal rocket control equipment in the forward instrument compartment, i.e.,\nthe gyros, radio apparatus, \"mischgeraete\" or electronic amplifier-mixer, etc.\nIn May 1945 United States Army Ordnance submitted a requirement for 100 com-\nplete V-2 rockets for trials in the United States, and later increased the order to 200\nsets of such major subassemblies as were available. By reason of this order, the\nMittelwerke was largely denuded of many of the parts which were there at the end of the\nwar. Of the main gyro and electrical-control units, complete demolition had been\n3.3(b)(1)\nTOP SECRET\n74"
