11 B-17s bombed Nordhausen airfield (the 511th Bombardment Squadron bombed Buchenwald/Nordhausen). In 1943, a Gustloff factory (in addition to one at Weimar) had been built at Buchenwald, and an August 1944 bombing destroyed the Buchenwald factory, killing many forced laborers. Salvaged equipment was moved to an underground salt mine in Billroda to resume production. One aircraft hit by wingman's gunfire crashed 8 miles North of Nordhausen. The 336th Fighter Squadron strafed the airfield.

Mission 669: 24 B-17s bombed.

Mission 748: 10 B-17s bombed the secondary target of Nordhausen.
The Combined Chiefs of Staff discussed a proposed Allied attack on the Nordhausen plant with a highly flammable petroleum-soap mixtureHLW:188 which, having been used in the Pacific theatre, filled the tiniest crevices and burned with intense heat. Instead, Nordhausen was subsequently lightly attacked with conventional bombers, but the vulnerable convict barracks (Camp ‘Dora’) were untouched.
