Constellation Software Engineering, LLC

Constellation Software Engineering, LLC, a Service-Disabled Veteran-Owned Small Business (SDVOSB) and Veteran-Owned Small Business headquartered in Annapolis, Maryland, operates as a federal prime contractor (88% of recent awards) and subcontractor across software development, engineering support, program management, and IT services. The company holds SBA certifications as both an SDVOSB and VOSB through March 19, 2028, and competes across both set-aside vehicles (predominantly Total Small Business and SDVOSB pools) and full-and-open competitions.

Constellation's customer base spans 36 federal agencies, but concentration diverges sharply between award count and dollar value. By award count, NASA Goddard Space Center leads with 25 awards ($24.1 million combined potential value), followed by GSA Federal Acquisition Service (10 awards, $1.02 billion), the Coast Guard (8 awards, $32.9 million), and the Bureau of Alcohol Tobacco Firearms and Explosives and Navy (6 awards each). By potential value, the ranking reshapes around three mega-vehicle IDIQs: the Department of Commerce National Oceanic and Atmospheric Administration tops at $3.01 billion across 5 awards, GSA holds $1.02 billion across 10 awards, the Department of Transportation Federal Aviation Administration carries $1.01 billion across 5 awards, and the Air Force $912.3 million across 5 awards. These four agencies account for 97% of combined potential value, driven primarily by Constellation's positions on two Government-Wide Acquisition Contracts and three large indefinite delivery vehicles. On operational contracts below the IDV level, the Coast Guard and Navy represent the most active defense customers, with task orders for construction project management, security engineering, and engineering support services.

Constellation holds a formidable vehicle portfolio anchoring its federal reach. On GSA GWACs, the company secured positions on POLARIS (both the SDVOSB-designated pool awarded February 1, 2026, and the Total Small Business pool awarded December 30, 2024), each carrying a multi-billion-dollar ceiling through 2030. The Missile Defense Agency awarded Constellation a $151 billion IDIQ for the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program on December 29, 2025, structured for multi-domain defense systems spanning air, missile, space, cyber, and hybrid domains (only a $500 initial delivery order has been issued to date). Constellation also holds the OASIS+ Total Small Business IDIQ (ceiling $999.999 billion, awarded December 19, 2024, through December 18, 2029) and the OASIS+ SDVOSB IDIQ (ceiling $999.999 billion, awarded September 30, 2024, through September 29, 2029), from which 20 task orders totaling $68.2 million in combined potential value have been drawn. On single-award vehicles, a $5.005 million DEA Indefinite Delivery Contract through June 30, 2026, supports key technical personnel for the Enforcement Programs and Information Center Tactical Operations Section, with three delivery orders totaling approximately $3.18 million issued against it. Constellation also maintains a $900 million Air Force Life Cycle Management Center IDIQ for multi-domain systems development and rapid prototyping through November 2027 and a $15 million Basic Ordering Agreement with the Office of the Secretary of Defense for the Joint Artificial Intelligence Center's AI Data Readiness through March 2027.

Representative recent prime work demonstrates the breadth: a $18.1 million firm fixed-price delivery order from the Navy's Chief of Naval Operations (September 2023, MAS) for base-year JAG JECE services at Cape St Claire, Maryland; a $5.4 million five-year firm fixed-price delivery order from the Coast Guard (January 2024, OASIS SB) for construction project management services in Juneau, Alaska, with an option-year exercise completed; a $3.21 million firm fixed-price Air Force delivery order (November 2024, MAS) for temporary engineering services supporting Sentinel A3 beddown at Francis E. Warren Air Force Base, Wyoming; a $2.87 million firm fixed-price Department of Veterans Affairs delivery order (September 2024, MAS) for construction management services; a $2.07 million firm fixed-price Air Education and Training Command delivery order (September 2025, OASIS+ SB) for program management support and construction inspection at Laughlin Air Force Base, Texas; and a $1.25 million Air Force Research Laboratory SBIR Phase II contract (May 2025) for HADRON, a decentralized data storage solution for air-gapped environments, performed at Cape St Claire. The company also holds active SBIR and Small Business Technology Transfer awards across the Air Force and Navy for supply chain security (blockchain and smart contracts), decentralized identity access management, and related R&D efforts.

Constellation operates as a primarily home-built prime across service contracts. SCI-reportable invoiced revenue totaled $19.5 million across FY2022–FY2024 ($5.8 million in FY2022, $4.2 million in FY2023, $9.4 million in FY2024), with delivery scaling from 22.3 FTEs in FY2022 to 50.5 FTEs in FY2024. Across SCI-reportable prime contracts, subcontractor hours average 14% of total delivery, with 11 named subcontractors; the vendor thus relies primarily on organic staffing. Government-paid hourly rates on prime service contracts run a median of $114.86/hr, with the 10th percentile at $60.96/hr and the 90th percentile at $206.47/hr. GSA Schedule labor categories (95 active) span from help desk and intern roles ($35.94/hr) through cybersecurity experts ($251.07/hr), with engineering technicians, cloud developers and architects, and program management specialists filling the mid-range ($86–$180/hr) and no security-cleared positions offered.

As a subcontractor, Constellation works under BAE Systems Technology Solutions & Services Inc. on integration and engineering services for the Intercontinental Ballistic Missile weapon system (multiple task orders, 2023–2024), ASRC Federal System Solutions LLC on program analysis and control (2023, 2025), and Space Network Solutions LLC on multidiscipline engineering support (2024). A 2025 sub-award under ASRC involves project planning and control for NASA Headquarters, Langley Research Center, and Goddard Space Flight Center facilities. A 2023 sub-award under Sikich Federal Inc. supports cybersecurity operations center services for the Indian Health Service.

Constellation is the parent of three subsidiaries: Alpine Testing Solutions, Inc.; RNS Ventures, LLC (which carries independent minority-owned, small disadvantaged business, SDVOSB, and Subcontinent Asian American-owned designations); and CSE Vets LLC (carrying self-certified small disadvantaged business and SDVOSB status). Six awards reach ultimate completion within the next twenty-four months, carrying combined potential value of $6.6 million and representing modest recompete exposure given the company's strong position on large multi-year vehicles.
