It Fits:

Believe it or not, weapons specialists at Whiteman AFB, Mo., have managed to fit a mock-up of the Massive Ordnance Penetrator—a 30,000-pound class weapon yet to enter production—in a mock-up of the B-2 bomber. Northrop Grumman got a contract last summer to begin the MOP integration effort for the B-2, expected to carry two MOPs in its internal weapons bays. Don’t confuse MOP with the 21,000-pound Massive Ordnance Air Blast, also known as the Mother of All Bombs for its acronym MOAB, which the Russians claim to have bested with the Father of All Bombs.
