US National Nuclear Security Administration reported the completion of the production of the first plutonium pit for the W87-1 Modification Program. The NNSA reported that

Plutonium pit manufacturing was completed at LANL, with Livermore Laboratory responsible for the pit design and KCNSC [Kansas City National Security Campus] responsible for production of non-nuclear components.

This process is part of the effort to rebuild the capability to manufacture plutonium pits. The production was stopped in 1989. The goal of the current program is to reach the capacity of 30 pits per year at LANL and "no fewer than 80 pits a year" across the nuclear enterprise.

The W87-1 warhead will be deployed on the Sentinel ICBM, which is currently under development.
