Doesn’t look like the B2 can carry either - unless bomb bay was modified - weight limit is 18,000 lbs.

Re: 18,000 lbs.
I believe that should be 18,000 kg.
The B-2 can carry 40,000 pounds of ordnance.
But, can it carry a MOAB inside its bomb bay?
I thought it could - but many people on this thread say no.
