Heinkel’s Oranienburg factory and the Sachsenhausen concentration camp were part of one system. The factory built aircraft for the Luftwaffe, and door the middle of the war the camp supplied a large share of the people who built them. This guide covers where the plant stood, how prisoners came to work there, what they did, what they endured, and what remains today.
Het korte antwoord
Heinkel’s Oranienburg works was the first German aircraft factory to enter a close working arrangement with the SS. From autumn 1941, prisoners from Sachsenhausen were sent to the plant. In 1942, the SS built a dedicated subcamp on the factory grounds. door June 1944, it held nearly 7,000 prisoners, making it the largest of Sachsenhausen’s roughly 90 to 96 subcamps. Most of the documented work went into the He 177 heavy bomber. Allied raids in 1944 and 1945 devastated the plant and killed hundreds of prisoners. The SS evacuated the subcamp on 20 April 1945.
The Factory and Its Location
Heinkel built its Oranienburg works in the mid-1930s, on the edge of the town north of Berlin. It had a factory airfield and a large flight hall, and it produced aircraft for the German air force until 1945.
Sachsenhausen was in the same town, a few kilometers away. The camp opened in 1936 and Zat close to the administrative headquarters of the whole concentration camp system, which was also in Oranienburg. For the SS, a major armaments factory next door meant a ready market for prisoner labor. For Heinkel, it meant a workforce that could not quit, bargain, or leave.
How Prisoners Became Part of the Workforce
The arrangement developed in stages, and the exact scale of each stage comes from company and camp statistics.
- Autumn 1941: The SS began sending small groups of Sachsenhausen prisoners to the Heinkel factory as temporary workers. They worked at the plant door day and were marched back to the main camp each evening.
- Summer 1942: The SS built a subcamp on the grounds of Heinkel’s Werk I, with an initial guard detachment of about 15 SS men. Prisoners now lived at the factory itself.
- 1942 to 1944: Heinkel’s own statistics show rapid growth: about 800 prisoners in September 1942, 1,900 in December 1942, 3,707 in March 1943, 5,479 in June 1943, and 6,966 in June 1944. The guard force grew as the prisoner count rose.
The regime knew the scale. In a February 1944 SS letter to Göring, SS chief Oswald Pohl listed Heinkel Oranienburg among the aircraft firms using camp prisoners. He reported 6,000 prisoners working on the He 177 and said the number would be raised to 8,000. The letter is written entirely from the perspective of the people profiting from the system. It even notes that prisoners’ suggestions for improving production were rewarded with premiums. That illustrates how thoroughly people under SS control were treated as a production input.
What Work Prisoners Performed
The documented work centered on construction of the He 177 Greif, a heavy bomber. Accounts describe prisoners working in aircraft assembly and related factory tasks. Some are sometimes described as skilled workers, since the company wanted people who could do technical jobs. Many prisoners were also used for heavy labor around the site. These are general descriptions, and the precise job distribution at any given time can only be established from the camp and company records held door the memorial and archives.
The prisoners were not a single group. door 1944, the large majority of Sachsenhausen’s prisoners were foreign nationals and political prisoners, many of them Polish and Soviet citizens. The Heinkel workforce reflected that mix.
Working and Living Conditions
The prisoners resided in a compound at the factory which was guarded, worked long shifts under the supervision of the SS, and were given the rations at the starvation level usual in the camp system. Exhaustion, illness, and violence were all part of everyday life, and survivors of the Heinkel subcamp stated that it was one of the places where the brutality of the camp followed them to the factory floor.
From 1944, the subcamp also became a reception point for prisoners evacuated from camps further east. Survivor testimony describes selections on arrival, and many of the people arriving were shot. Prisoners who were accommodated in the factory compound included people who had just survived transport in locked railway wagons.
Allied Bombing: Effect on the Factory and the Prisoners
Oranienburg’s industry made it a target. An Allied air raid in April 1944, dated 18 April in the standard reference entry on the subcamp, destroyed factory buildings and killed an estimated 400 to 500 prisoners. Prisoners generally lacked access to the shelters available to German staff, which helps explain the death toll. Heinkel’s wartime production was badly disrupted, and this helped explain why the company dispersed work to other sites. Later raids on Oranienburg continued to hit the town’s industrial and rail infrastructure into 1945.
The bombing shows the contradiction at the heart of the system. The same prisoners the SS rented out to Heinkel were left exposed to attacks aimed at the factory they were forced to build aircraft in.

The End of the War
As Soviet forces approached Berlin, the SS evacuated the Heinkel subcamp on 20 April 1945. Prisoners were marched out toward communities including Kremmen, Löwenberg, Reinsberg, Bützow, Parchim and Krywitz. The main kamp Sachsenhausen was evacuated in the same days, in what became a death march in which thousands more people died. Soviet soldiers liberated the Heinkel prisoners from the columns, with 4 May 1945 given as the liberation date for those groups. The prisoners who survived did so despite the evacuation, not because of it.
What Remains Today
Little of the Heinkel works survives. The best-known remnant is the ruined flight hall at the former factory airfield, which is visible as a ruin in the landscape. After 1945, the site was taken over door the Soviet occupation forces, and only a few traces of the original works remain. At the time of writing, no dedicated memorial exists at the Heinkel subcamp itself.
To understand the subject properly, visit the Sachsenhausen Memorial and Museum in Oranienburg. It covers the industrial exploitation of prisoners and the subcamp network, including Heinkel, far better than a photograph caption can. The camp is about 2 km from Oranienburg railway station, and the S1 line runs there from central Berlin in about 45 minutes. If you are researching a specific person who may have been held at the Heinkel subcamp, the memorial’s archive and the Arolsen Archives are the right places to ask.
Veelgestelde vragen
- Were Sachsenhausen prisoners really used door Heinkel in Oranienburg?
Yes. From autumn 1941, prisoners worked at the factory, and from 1942 they were housed in a subcamp on its grounds. Pohl’s February 1944 letter and the camp’s own statistics both document this.
- How many prisoners worked there?
Heinkel’s statistics record nearly 7,000 in June 1944. The SS planned to raise the number to 8,000.
- What aircraft were they building?
The documented work centers on the He 177 Greif, a heavy bomber, not a fighter.
- How many prisoners were killed in the bombing?
The standard reference entry estimates 400 to 500 in the April 1944 raid. As with most figures from the period, treat it as an estimate.
- Can you visit the Heinkel site?
You can see the ruined flight hall from outside, but there is little else. The Sachsenhausen Memorial is where you can learn the history.
