The tri-service EOD school in Kent use Tallboys/Grandslams as gate guardians (or more accurately fence posts - there are quite a few of them. As for carrying them, most cargo a/c could carry them (including the Hercules) and most modern comabt a/c could carry them, the main problem would be (with the exception of B1 and B52) the necessity of external carriage. The modern guided weapons are the GBU28/B (laser guided) and the GBU37/B (GPS guided) bunker-busters.
