About this vehicle
The Defense Threat Reduction Agency awarded this Master IDIQ on August 1, 2022 to counter chemical, biological, radiological, nuclear, and high explosives threats through assessments, exercises, modeling and simulation support. The vehicle carries a total small-business set-aside. Ordering authority extends through July 31, 2027, leaving approximately 13 months of ordering horizon.
Only two task orders have been awarded against the vehicle, both in late September 2023, establishing minimal recent ordering momentum. Combined potential value stands at $22 million with $13.9 million obligated to date (63% of ceiling). The shared vehicle ceiling is $850 million, indicating substantial available capacity.
Two primes split the awards equally by potential value: Rmgs Inc. holds one order valued at $11.1 million (ceiling), and Obsidian Solutions Group LLC holds one order valued at $10.8 million (ceiling). Both awards fund DTRA nuclear enterprise mission assurance work—one blending asset management and IT research support (cost-plus-fixed-fee) and the other focused on operations support (firm fixed price). Ultimate completion dates for both orders fall in late September 2028.
The vehicle is fully concentrated within DTRA as the customer. The total-small-business set-aside structure restricts competition to certified small businesses, reflecting the originating solicitation (HDTRA120R0076) issued January 27, 2021 with an April 5, 2021 due date (subsequently amended to extend the deadline). The predecessor solicitation describes the originating requirement as a follow-on to prior DTRA CBRNE support contracts, with NAICS code 541715 and place of performance at the contractor's facility.
With 13 months remaining in the ordering window and only two orders awarded across nearly three years of vehicle life, activity has been sparse. The $850 million shared ceiling and modest task-order takeup to date suggest capacity for additional orders, though the slow pace and concentration of early work within nuclear enterprise mission assurance may signal a narrowly focused vehicle with limited growth potential outside that mission set.
