I thought we just discussed this a ccouple months ago and I got proven
wrong :-) I think it wass pretty well decided that grand slam was not used
on Tirpitz. I believe that tallboy the 12000 lb derivitive of grand slam was
used against Tirpitz (also against the sub pens) I saw the disccovery channel
show on the lancaster the other night. they had footage of a grand slam and
a dam buster being dropped. Pretty good show. Grand Slam was the largest
cconventional bomb used. the vietnam era big bomb was usedto clear landing
zones and I believe was a fuel/air bomb it weighed about 15000 lb
