Dss+ Transportation LLC

Dss+ Transportation LLC, a foreign-owned for-profit corporation based in Baltimore, Maryland, operates exclusively as a subcontractor to federal primes, with all eleven recent awards (100% of the portfolio) issued as sub-awards under Peraton Inc. and Hanford Tank Waste Operations & Closure, LLC. The vendor has no prime contract vehicles and does not compete for direct federal contract awards.

The vendor's recent footprint is heavily concentrated within the Department of Transportation's Federal Aviation Administration. Ten of eleven awards flow through FAA channels—seven to FAA Headquarters and three to FAA Enroute Terminal Contracts—with a single award from the Department of Energy's Office of Environmental Management. All work is routed through two parent IDICs: Indefinite Delivery Contract 693KA726D00003 (ten task orders under Peraton) and Indefinite Delivery Contract 89303324DEM000096 (one task order under HWOC). The category portfolio splits between Computer Systems Design Services (ten awards) and Hazardous Waste Treatment and Disposal (one award), reflecting dual operational tracks.

Recent sub-award activity centers on air traffic control system integration and modernization. Under Peraton, Dss+ Transportation performs work on multiple named needs packages tied to FAA's modernization roadmap: the EIDS, SAI, TFDM, and RADARS programs; the Base National Air Traffic Control System (BNATCS) Integrator Accountability Contract for Tower Simulation Systems integration; the BNATCS TDM-IP telecommunications infrastructure integration; and the BNATCS voice-switch communication workstream. The single Department of Energy sub-award, issued December 2025 through HWOC on Hanford Tank Waste Operations, focuses on health and safety evaluation (worker exposure assessment to acetonitrile at the Effluent Treatment Facility).

Activity is nascent. The source captures only one award in 2025 and ten awards between January and March 2026, with combined dollars obligated totaling $7 million across the eleven sub-awards. Service Contract Inventory data show minimal federal service-contract reporting: two SCI records spanning FY2022–FY2024, with roughly 4.3 FTEs in FY2022 and 5.1 FTEs in FY2024, both recorded as subcontractor activity only. The SCI figures represent a strict subset of the vendor's federal services footprint and do not capture goods, products, classified work, or the majority of the recent sub-award volume. Dss+ Transportation's role is consistent with a feeder subcontractor model: the vendor delivers specialized support to a single dominant prime (Peraton) on time-and-materials or cost-reimbursable delivery orders within FAA modernization scope.
