That's interesting since, by then, the ageing B-29 was considered a "medium" bomber. Plus, with the construction of B-50s between 1947 and 1953 - 1953 being the cease-fire year - one would think that they made at least a few sorties. I did find that of the 34 B-29s lost in the war that 16 were due to fighters, 4 to Flak and 14 to other causes.
