Why bomber volume can matter more than lifting power

How many Grand Slam-size bombs could a B-52 or B-2 carry?

Perhaps three for a B-52 and one or two for a B-2, as a rough estimate based mainly on physical space.

The estimate is three Grand Slam-size bombs for a B-52 and one or perhaps two for a B-2. Physical room is the main constraint. The suggested B-52 arrangement places one weapon under each wing root and another in the bomb bay. The B-2's bay dimensions make even two weapons uncertain, with diagonal carriage suggested as a possibility. These are hypothetical arrangements based on space, without a demonstrated installation. A later comparison with the small A-4 Skyhawk reinforces the distinction between an aircraft's size and the weight of weapons it can carry.
