The B61-12 will replace a 1-megaton nuclear bomb called the B83 (below). Retiring those weapons will cut the total number of nuclear gravity bombs by 50%. They'll pull 83% of weapons-grade nuclear materials out of the old bombs and use the remainder for new ones.

The new bomb has to work, of course. As part of an impact test in January 2015, Sandia Labs fired a dummy B61-12 bomb from its giant Davis Gun in New Mexico.

The test recalls the 'Upshot Knothole' atomic cannon, which could fire a nuclear shell more than 6 miles away.
