About the company

Mission Support & Test Services LLC, a for-profit limited liability company based in North Las Vegas, Nevada, operates as a prime contractor delivering fleet vehicle maintenance and automotive mechanical repair services to federal agencies on a predominantly full-and-open basis, with occasional small-business set-aside work. The vendor does not hold formal SBA designations but qualifies as a small business under federal criteria and carries primary NAICS classification 811111 (General Automotive Repair) and PSC coding aligned with ground-effect vehicle and motor-vehicle maintenance and repair.

The vendor's customer footprint is heavily concentrated with the General Services Administration's Federal Acquisition Service, which accounts for 18 awards totaling $177 thousand combined potential value across recent purchase orders for automotive mechanical repairs — engine replacement, turbo and fuel system work, and routine fleet maintenance. However, the dollar concentration tells a different story: a single Department of Energy National Nuclear Security Administration award for Nevada National Security Sites disposal services carries $11.3 billion in combined potential value, representing 99.8% of the vendor's total potential value across all awards. This outsized exposure stems from a subcontract award dated June 30, 2026, to Ut-Battelle LLC for management and operation support related to Oak Ridge National Laboratory and NNSS, a multi-billion-dollar program running through the recompete window in the next twenty-four months. The Department of Energy Office of Science accounts for one additional award with no stated dollar value.

The vendor's recent activity shows a modest but volatile trajectory: four awards in 2021, three in 2022, one in 2024, five in 2025, and four in 2026. GSA purchase orders for automotive repairs cluster in the $1,500 to $29,000 range with firm fixed pricing and ultimate completion dates typically within three to six months of award. Mission Support & Test Services LLC registered in SAM.gov in December 2015 and has maintained a continuous though episodic presence in federal contracting, with performance location consistently at its North Las Vegas facility or at customer locations within a defined service radius. The single subcontract relationship noted is with Ut-Battelle LLC on the NNSS disposal services work, representing the only identified prime-contractor teaming in the source data. The vendor's recompete exposure in the next twenty-four months is driven entirely by the Ut-Battelle sub relationship, given that GSA purchase orders typically complete within months of award.
