NNSA Celebrates First-Phase Achievement of Major Infrastructure Project in Kansas City

The first phase was completed ahead of schedule and on budget, meeting production demands

WASHINGTON - The Department of Energy's National Nuclear Security Administration (DOE/NNSA) announced the completion of Phase One of the Kansas City Non-Nuclear Expansion Transformation (KC NeXT). NNSA assumed property ownership ahead of schedule and on budget. Phase One includes a 700-seat classified office building.

"In a rapidly changing national security environment, modernizing the enterprise to be more adaptive, agile, responsive, and resilient is more critical than ever before," said NNSA Administrator Brandon Williams. "The KC NExT project is one of the latest examples of how innovative approaches coupled with strategic investments in our infrastructure are accelerating our mission."

To meet increasing production demands, NNSA launched KC NExT in 2024, a multi-phase real estate acquisition strategy to add approximately two million square feet of cutting-edge office and manufacturing space. KC NExT is designed to deliver results from day one. Each completed phase will be operational even as construction continues onto the next phases. This ensures steady progress and uninterrupted momentum throughout the entire project.

The first manufacturing building under Phase Two began construction near the end of 2025, and agreements have been finalized for Phase Three's support facilities. NNSA expects to begin construction on a new phase each year through the 2030s.

NNSA remains committed to modernizing its production and infrastructure capabilities to build a more flexible and resilient enterprise that can quickly adapt to shifting mission requirements and keep pace with evolving threats.

Kansas City National Security Campus is a vital part of the Nuclear Security Enterprise and produces over 80 percent of the non-nuclear mechanical, electronic, and engineered material components for the U.S. nuclear deterrent.
