Well the heavy bomber was the A7 Savage, the primary reason why she was designed.
Indeed, some great planes. Heavy, two turboprops, and place for nukes, Hhahahah.
Just a nitpick: the Savage wasn't a turboprop, it just had regular piston engines - although it did have a jet engine in the fuselage! I believe it was for extra speed both on take-off and to squeeze a few more knots for a quick getaway.
