The correct answer to this question is Luftwaffe. Operation Bodenplatte was a surprise attack carried out in hopes of crippling the Allied forces. It was apart of the Battle of the Buldge, which occurred during World War II. It was originally planned for December 16, 1944, but it didn't start on January 1, 1945.
The delay was due to bad weather. During the operation, there were 16 allied bases that were attacked. The 16 bases were in France, Belgium, and the Netherlands. The goal of the operation was to gain air control, but in the end, the operation failed. The Germans also had a German tactical success.
