“Over the past four months, our employees – at all levels – worked tirelessly to ensure we were 100 percent prepared to hit the ground running on day one as the NNSS’ Management and Operating contractor,” Martinez said. “The work of the NNSS is vital to the nation, and to national security, and we couldn’t be more excited to continue the scientific work that the NNSS is known for.”

Martinez and his executive management team collectively hold roughly 300 years of leadership experience supporting national nuclear security. They come from parent companies Honeywell, Jacobs and SN3 with backgrounds at Lawrence Livermore National Laboratory, Los Alamos National Laboratory, the Kansas City National Security Campus, the Nevada National Security Site, the Pantex Plant, the Savannah River Site, and the U.K. Atomic Weapons Establishment..

MSTS staff collaborated closely with the former NNSS M&O contractor, National Security Technologies, LLC from Aug. 1 – Nov. 30 to ensure a smooth transition. Within the NNSS contract, MSTS employs nearly 2,400 people across numerous facilities: Livermore Operations, New Mexico Operations, Remote Sensing Laboratory-Nellis Air Force Base, Remote Sensing Laboratory-Joint Base Andrews, Special Technologies Laboratory, North Las Vegas facility and the NNSS.

The Nevada National Security Site and its related facilities help ensure the security of the United States and its allies by: supporting the stewardship of the nation’s nuclear deterrent; providing nuclear and radiological emergency response capabilities and training; contributing to key nonproliferation and arms control initiatives; executing national-level experiments in support of the National Laboratories; working with national security customers and other federal agencies on important national security activities; and providing long-term environmental stewardship of the NNSS’s Cold War legacy.

The NNSS falls under the jurisdiction of the National Nuclear Security Administration, a semi-autonomous agency within the U.S. Department of Energy (DOE). The Site’s operations are government-controlled and contractor-operated. They are overseen by DOE’s Nevada Field Office, headquartered in North Las Vegas.
