Regarding the largest bombs carried by German bombers during WW2 -
I seem to recall reading years ago an article that in effect stated
British bombs and shells were made up from a mixture that produced a less
powerful bomb compared to its German equivilant. If true then this
would suggest that a German 1000lb bomb could cause greater
destruction than a British bomb of identical weight.
I seem to recollect that either torpex - or it may have been aluminium filings were not added in sufficient quantities or mix to create greater explosive effect - but had this been realised and action taken then the RAF could have caused the same amount of bomb damage useing fewer aircraft - and fewer losses.
