During 1942, the focus of the SS shifted towards war production, leading to negotiations with arms manufacturers to license their products to DEST. Messerschmitt AG was one of the most important armaments companies that demonstrated interest in acquiring the slave labor of concentration camp prisoners, opening negotiations with DEST via Regensburg by the end of 1942 to produce parts for the Messerschmitt Bf 109 aircraft at Flossenbürg. Under the terms of the deal, Messerschmitt would provide skilled technicians, raw materials, and tools, paying DEST 3 Reichsmarks per day for a skilled laborer and 1.5 Reichsmarks per day for an unskilled prisoner. Thus, Messerschmitt could increase its profit margin by reducing labor cost, while DEST could reduce its administrative costs by acting as a manpower agency. In mid-January 1943, DEST accepted the offer; production started in early February.
