LAS VEGAS — A subsidiary of defense giant Lockheed Martin has been awarded a $5 billion contract to manage a vast federal Department of Energy reservation where the nation used to conduct nuclear testing north of Las Vegas.
An announcement Friday by the National Nuclear Security Administration said a five-year contract with a five-year option went to Nevada Site Science Support and Technologies Corp.
The Lockheed Martin affiliate plans to partner with a subsidiary of Fluor Corp. and Longenecker and Associates.
The 1,360-square-mile area, now called the Nevada National Security Site, is used for experiments and safety training related to the nation’s nuclear stockpile.
It had been managed by National Security Technologies LLC. That’s a Northrop Grumman joint venture with three other partners.
As the Nevada Test Site, the area hosted more than 1,000 nuclear detonations from 1951 to 1992.
