NNSA announced the successful completion at the Pantex Plant outside of Amarillo, Texas, of efforts to refurbish the W87 nuclear warhead and extend its life by 30 years. This marks the end of the first leg of NNSA’s program to ensure that the nation's aging nuclear weapons stockpile is capable of meeting national defense requirements without producing new warheads or conducting underground nuclear tests. Other warheads undergoing planned life extension refurbishments include the B61, W76, and W80.
