NVS3T awarded contract to manage Nevada National Security Site

Nevada Site Science Support and Technologies Corp. was awarded a $5 billion, 10-year contract to manage and operate the Nevada National Security Site, officials for the National Nuclear Security Administration said Friday.

The company, known as NVS3T, will take over Sept. 30 for National Security Technologies LLC, with both companies sharing a four-month-long transition period, said a spokeswoman for the National Nuclear Security Administration, a branch of the Department of Energy.

Five competitors vied for the contract, which is valued at $5 billion through 2026 if all options are exercised.

NVS3T, headquartered in Gaithersburg, Maryland, is a wholly owned subsidiary of Lockheed Martin Integrated Technology LLC. Two other companies — Fluor Federal Services and Longenecker and Associates — will support NVS3T at the government’s 1,360-square-mile Nevada National Security Site.

The security site, 65 miles northwest of Las Vegas, was formerly known as the Nevada Test Site where full-scale nuclear weapons tests were conducted from 1951 to 1992. Among its current missions is to help ensure the safety and reliability of the nuclear weapons stockpile through science-based experiments.
