Contract Award Provides Best Value to the Government and Workforce Stability for a Decade

WASHINGTON, D.C. – The National Nuclear Security Administration (NNSA) announced today it has awarded Mission Support and Test Services LLC (MSTS) with the management and operating contract for the Nevada National Security Site (NNSS) near Las Vegas, Nev.

MSTS is a limited liability company consisting of Honeywell International Inc. (Honeywell), Jacobs Engineering Group Inc. (Jacobs), and Stoller Newport News Nuclear, Inc. (SN3).

NNSA conducted a full and open competition for the follow-on NNSS M&O contract. The award is valued at $5 billion over 10 years if all options are exercised. Evaluation criteria included past performance, proposed management and key personnel, small business utilization, and cost.

“The Nevada National Security Site plays a critical role in maintaining the nation’s nuclear deterrent and supporting other vitally important national security missions,” said Lt. Gen. Frank G. Klotz (Ret.), Under Secretary for Nuclear Security and NNSA Administrator. “This full and open competition generated tremendous interest from industry and ensures the government will receive the best value for management and operations at the site.”  

The 1,360-square mile NNSS is an experimental testing facility and training ground supporting a variety of nuclear nonproliferation and advanced-technology missions vital to national security. NNSS contributes to the safety, reliability, and security of the nuclear weapons stockpile through scientific experiments supporting the science-based Stockpile Stewardship Program. NNSS also provides radiological/nuclear emergency response capabilities and training, and—as a former nuclear test site—also serves as a major center for research and development advancing international nuclear monitoring and verification capabilities.

The current M&O contract for NNSS will be extended beyond its expiration date of May 31, 2017, in order to allow for a full four-month transition period.
