Mbclark LLC

Mbclark LLC, a sole proprietorship, subcontracts systems security analysis and space-system resilience engineering to The Mitre Corporation on Department of the Air Force programs, operating exclusively as a subcontractor with no prime awards in recent activity.

The vendor's federal footprint is narrow and recent. Four sub-awards placed between November 2023 and November 2023 (all on the same date, representing modifications to a single underlying task) total $208 thousand in combined obligation and work under the Mitre prime on a single Air Force contract vehicle (Indefinite Delivery Contract W56KGU18D0004). All work falls under NAICS 541715 (Research and Development in the Physical, Engineering, and Life Sciences, except Nanotechnology and Biotechnology). The named capability is System-Theoretic Process Analysis for Security (STPA-Sec) applied to space system security and resilience, with performance period running through December 31, 2023. The four line items documented in the source represent administrative modifications — corrections to line of accounting, fund deobligations — rather than scope expansion, and the work appears complete as of the 2023 year-end performance cutoff.

Customer concentration is singular: all four awards fund Department of the Air Force Headquarters District Washington programs. The vendor has served no other federal agencies in the source data window. No SBA designations (8(a), HUBZone, SDVOSB, WOSB, or others) are present in the source. The vendor carries no IDVs, GWACs, BPAs, or parent vehicles of its own; all work flows through Mitre's contracting relationships. Activity has not recurred since late 2023, and no awards appear in 2024 or 2025 in the source data.
