I don't think that the Bristol Blenheim belongs on anyones top bomber list. That aircraft was obsolete by the time it got into service and didn't do too well in combat. The Tu-22 would make my list. After the B-52 it was the best Cold War bomber. Why? Because it was capable of penetrating deep into NATO airspace, sinking carriers, droping conventional bombs and suitable for the long haul missions it would have to fly. Just its exsistence and the Kitchen missles it could fire forced the USN to change their doctrine.
