Shores, 2nd TAF, p. 7, /"... fighter-bombers, which required an average
of between 100 and 200 tons of bombs and rockets to destroy a bridge,
compared with 640 tons for level bombers."/
Since one bomb is pretty much the same as any other of the same weight,
accuracy is the issue and 100-200 tons refers to total delivered with
fighter-bomber accuracy.
Of course, some bridges would be metal girders, others stone or even
wood. But is makes the amount we drop to destroy a bridge look nowhere
near enough.
