Video of handling of nuclear warheads at a NNSA facility

NNSA released an official video of nuclear warheads being handled by personnel of a NNSA facility, most likely in preparation for refurbishment:

The nuclear warheads in the video are either an Mk-12A/W78 or an Mk-21/W87 ballistic missile warhead and a B83 gravity bomb. All these weapons remain in U.S. active arsenal and will be supported in the future.
