its an each way bet as to whether soviet aircraft would be carrying Soviet or Allied bombs, but my bet is that an American aircraft would carry American bombs
The US alone supplied 317,000 tons of bombs (thats just the explosive content of the warheads incidentally) that was equal to just over half of the total Soviet production of approximately 600,000 tons produced by home sources. The Soviets also acquired thousands of US jigs and dies from the US, including the equipment needed to make US pattern ordinance of nearly every kind including bombs. the US. Additionally the Allies supplied 103,000 tons of toluene, the primary ingredient of TNT. In addition to explosives and ammunition, 991 million miscellaneous shell and bomb casingswere also provided to speed up the manufacturing of ammunition.
