Decision Engineering Corporation

Decision Engineering Corporation, a for-profit Subchapter S corporation based in Ambler, Pennsylvania, operates primarily as a subcontractor (69% of recent awards) with an emerging prime presence on defense and civilian GSA vehicles, delivering systems engineering, C2 and sensor integration, and technical support services to Department of Defense and federal civilian agencies under full-and-open competition with no set-aside designations.

Decision Engineering's prime footprint centers on two high-ceiling vehicles awarded in late 2025. On December 29, 2025, the Missile Defense Agency awarded Decision Engineering a seat on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ—a multi-award, 10-year indefinite-delivery contract with a $151 billion ceiling spanning research and development, systems engineering, weapons design, test and evaluation, and cyber and modernization work across air, missile, space, and hybrid domains. The initial task order under SHIELD carries a $500 ceiling and completion date of December 28, 2035, with performance in Huntsville, Alabama. One month prior, on October 17, 2025, GSA's Federal Acquisition Service awarded Decision Engineering a seat on the OASIS+ Total Small Business set-aside IDIQ, a multiple-award vehicle with a five-year base period and one five-year option through October 16, 2030, spanning seven functional domains including Management and Advisory, Technical and Engineering, and Research and Development. Decision Engineering also holds a GSA Multiple Award Schedule contract (Federal Supply Schedule, awarded September 28, 2023, ceiling $475,000, through September 27, 2028) offering IT and professional services labor categories including engineering specialties, project managers, software engineers, and subject matter experts.

The subcontractor footprint is concentrated. Nine of thirteen recent awards route through Parsons Government Services, all characterized as C2 and LSI (Logistics and Supply Information) engineering services with incremental funding modifications dated between November 2023 and November 2024. This Parsons sub work aligns with Decision Engineering's stated prior experience on Department of Defense programs alongside Booz Allen Hamilton and Polaris Alpha Advanced Systems on systems engineering and technical support.

Customer concentration is split between defense and civilian GSA channels. The Army Acquisition Support Center PEO Intelligence, Electronic Warfare & Sensors and Air Force Space and Missile Systems Center account for nine awards combined, driving the sub-heavy posture under Responsive Strategic Sourcing for Services (six task orders) and Alliant II (three task orders). GSA Federal Acquisition Service contributes two awards valued at $475,000 combined potential value, anchored by the new OASIS+SB vehicle. The Missile Defense Agency contributes two awards (the SHIELD IDIQ and initial task order) valued at $500 combined potential value. Over the past three years, award volume has been steady at five awards per year (2023 and 2024) with three awarded to date in 2025.

The SCI dataset shows minimal federal services invoicing activity: the source reports six SCI records across fiscal years 2022–2024, all as named subcontractor engagements (zero as prime), with a workforce trajectory from 5.6 FTEs in FY2022 to 16.6 FTEs in FY2024. This SCI-reported activity is a narrow slice of federal services work and does not capture the full scope of Decision Engineering's systems engineering and C2 LSI delivery.
