Leidos Security Detection & Automation, Inc.

Leidos Security Detection & Automation, Inc. Security & Detection Systems Division, doing business as Leidos QTC Health Services, is a wholly owned subsidiary of Leidos, Inc. that manufactures, installs, and maintains advanced security screening and detection equipment for federal agencies as a prime contractor (99% of recent awards) on full-and-open, non-set-aside procurements. The division is headquartered in Tewksbury, Massachusetts and operates under NAICS 334517 (Search, Detection, Navigation, and Guidance System Manufacturing) and PSC codes J067 and J063, specializing in explosive detection systems, radiation portal monitors, automated security lane equipment, body scanners, baggage X-ray systems, and trace detection technologies.

The division's customer base is heavily concentrated in Department of Homeland Security components, particularly the Transportation Security Administration. TSA accounts for 271 awards and $5.09 billion in combined potential value—74% of all awards in the source portfolio and 74% of total potential value across all 120 customer agencies served. The next-largest customer by potential value is DHS Countering Weapons of Mass Destruction (11 awards, $344.5 million), followed by GSA Federal Acquisition Service (6 awards, $123 million) and DHS Science and Technology Directorate (6 awards, $31.8 million). Immigration and Customs Enforcement and the Department of State round out the active set by award count (30 and 31 awards respectively, though at significantly lower dollar values). This concentration is extreme and stable: TSA's dominance recurs across both award-count and potential-value rankings, and the division holds two substantial single-award IDIQs with TSA valued at $363 million (Explosive Detection Systems Type 1 and Type 2, awarded September 2025, running through September 2032) and $115.8 million (Security Screening and Detection Systems, awarded September 2023, running through September 2030).

Recent representative prime work includes a $48.5 million firm fixed-price definitive contract from TSA awarded September 2023 for purchase and installation of 33 medium-speed explosive detection systems at various airports with ultimate completion in September 2031; a $20.3 million delivery order from TSA in September 2024 for 17 medium-speed explosive detection systems with installation services and ancillary equipment; a $19.7 million delivery order from TSA in May 2024 for purchase and installation of medium and reduced-size explosive detection systems; a $19.6 million delivery order from TSA in September 2023 for Leidos STSS system management services (Vienna, Virginia, extending through September 2030); a $650,472 delivery order from DHS Countering Weapons of Mass Destruction in September 2024 for installation and on-site deployment support; and routine maintenance and support orders from Immigration and Customs Enforcement, FEMA, Army Southern Command, the Air Force, and the Court Services and Offender Supervision Agency for X-ray system maintenance, body scanner maintenance, trace detection equipment, and spare parts.

The division's primary vehicle position is anchored by the two TSA IDIQs noted above. Task orders under the Medium Speed Explosive Detection System vehicle number 84 with $281.9 million combined potential value, while the Indefinite Delivery Contract HSTS0411DCT1115 carries 27 task orders worth $81.5 million and HSTS0417DCT1087 carries 23 task orders worth $58.2 million. The division also holds a position on the Federal Supply Schedule GS07F9059D, which carries 308 task orders with $7.6 million in combined potential value, primarily for repair and maintenance services.

Activity has fluctuated modestly in recent years—13 awards in 2022, 10 in 2023, 14 in 2024, 8 in 2025, and 7 so far in 2026 (most recent award September 30, 2026)—with 14 awards (combined potential value $80.8 million) reaching ultimate completion within the next twenty-four months and therefore presenting recompete opportunity. Total awards in the source dataset span 978 prime and sub awards dating back to 1996, with combined potential value of $6.89 billion and combined obligated dollars of $1.63 billion (24% of potential value).

SCI-reported invoiced revenue on federal service contracts captured above the $150,000 reporting threshold amounted to $26.7 million across fiscal years 2022–2025, with notable volatility: $14.8 million in FY2022 (0.9 FTEs contract-level), $5.2 million in FY2023 (14.8 FTEs), $2.8 million in FY2024 (5.6 FTEs), and $3.9 million in FY2025 (5.7 FTEs). On federal services contracts, the division self-performs substantially all labor; across prime contracts captured in SCI, sub-hours accounted for 1% of total contractor hours, with only one named subcontractor reported. Government-paid hourly rates on these service contracts ranged from a 10th percentile of $136.01 per hour through a median of $239.36 per hour to a 90th percentile of $2,325.47 per hour, reflecting a mix of equipment engineers, technicians, and program management labor.

The division also operates as a subcontractor to Science Applications International Corporation on infrastructure support and systems integration work (Federal Lands IT support, Integrated Multi-Domain Command and Control technical support, maritime GCCS production) and to PAE Government Services, Inc. on international aviation security training and technical assistance programs. These sub-engagements represent 11 awards across the portfolio and reflect the division's specialized detection-equipment expertise being leveraged within larger prime teams.
