Supplying the 270,000 men trapped in the "cauldron" required 700 tons of supplies a day. That would mean 350 Ju 52 flights a day into Pitomnik. At a minimum, 500 tons were required. However, according to Adam, "On not one single day have the minimal essential number of tons of supplies been flown in." The "Luftwaffe" was able to deliver an average of 85 tonnes of supplies per day out of an air transport capacity of 106 tonnes per day. The most successful day, 19 December, the "Luftwaffe" delivered 262 tonnes of supplies in 154 flights. The outcome of the airlift was the Luftwaffe's failure to provide its transport units with the tools they needed to maintain an adequate count of operational aircraft – tools that included airfield facilities, supplies, manpower, and even aircraft suited to the prevailing conditions. These factors, taken together, prevented the Luftwaffe from effectively employing the full potential of its transport forces, ensuring that they were unable to deliver the quantity of supplies needed to sustain the 6th Army.
