The National Nuclear Security Administration announced this week it entered into a multi-year agreement in May to expand operations and office space at the Kansas City National Security Campus in Missouri.

The National Nuclear Security Administration (NNSA) made the agreement with Promontory 150 LLC in May to purchase both land and what a spokesperson for the Kansas City National Security Campus (KCNSC), in an email to the Monitor, called a “build-to-suit” facility.

KCNSC is NNSA’s factory for non-nuclear nuclear-weapon parts. The new facilities will aid with designing, testing, and production of non-nuclear weapons components, according to the press release announcing the real-estate deal.

The KCNSC spokesperson told the Monitor that this first phase of the project, called the Kansas City Non-Nuclear Expansion Transformation (KC NExT), is “envisioned to be the first of several purchase agreements under this project.” The cost for phase one would be $199 million, paid upon completion of the building, which is set to be completed in the summer of 2026, the spokesperson said.

KC NExT aims to add around 2.5 million square feet of manufacturing and office space to accommodate growth in KCNSC, according to the release.

“KCNSC has experienced significant growth in workload and personnel to support NNSA’s planned modernization of the nuclear deterrent,” the NNSA wrote in the release.
