The U.S. Department of Energy’s National Nuclear Security Administration (NNSA) said the construction of Pantex Plant’s High Explosives Science and Engineering (HESE) facility has been completed
The new facility consolidates 15 aging facilities, which will strengthen U.S. nuclear security and weapons infrastructure. Officials said the HESE refines the space for technology development supporting the plant’s weapons maintenance and surveillance mission, and will bring key high explosives science, engineering and technology development functions under one roof.
“This facility is a major step forward in strengthening and modernizing America’s nuclear deterrent,” NNSA Administrator Brandon Williams said. “Critical missions have relied on World War II-era infrastructure for far too long that do not meet today’s security challenges. This facility changes that. HESE will give Pantex the modern, mission equipped space needed to advance essential high-explosive work—and it’s built for what comes next. That’s how we deliver a safe, secure, and reliable deterrent and uphold our commitment to peace through atomic strength.”
The NNSA’s Pantex Plant is America’s primary site for the final assembly, dismantlement and maintenance of nuclear weapons. Officials said HESE will support technological development tied to weapons maintenance and surveillance, while helping Pantex accommodate future modernization and production requirements.
“The new High Explosives Science and Engineering facility is a landmark achievement, setting an unprecedented standard for high explosives research and development crucial to national security,” PanTeXas Deterrence President and General Manager Kelly Beierschmitt said. “This state-of-the-art facility not only exemplifies American ingenuity but also demonstrates our unwavering commitment to mission success. My sincere appreciation to all the Pantexans and others who made this happen.”
