Which nuclear weapons facility is recognized as the largest storage facility for nuclear weapons in the world?

The Kirtland Underground Munitions Maintenance Storage Complex (KUMMSC) is recognized as the largest storage facility for nuclear weapons in the world due to its vast underground capacity designed to safely house and maintain nuclear munitions. This facility is strategically positioned within the Kirtland Air Force Base, leveraging a robust infrastructure that ensures security and protection against potential threats.

KUMMSC is equipped with advanced systems for surveillance and environmental controls, making it highly suitable for the sensitive nature of nuclear weapon storage. Its design allows for the long-term storage of various types of nuclear arms while maintaining compliance with stringent safety regulations.

In contrast, other facilities like the Los Alamos National Laboratory and Sandia National Laboratories primarily focus on research and development related to nuclear materials and weapons but do not serve the same purpose for large-scale storage. Similarly, although the Pantex Plant is known for nuclear weapon assembly and disassembly, its primary function is not large-scale storage, which differentiates it from KUMMSC.
