Leidos Security Detection & Automation, Inc.

Leidos Security Detection & Automation, Inc. Security & Detection Systems Division, doing business as Leidos QTC Health Services, manufactures and services explosive detection systems, radiation portal monitors, body scanners, and related security screening equipment for federal agencies as a prime contractor (99% of recent awards) competing through full and open competition with no SBA set-asides. The company is a wholly owned subsidiary of Leidos, Inc., headquartered in Tewksbury, Massachusetts, operating under primary NAICS 334517 (Search, Detection, Navigation, and Guidance System Manufacturing) and PSC codes aligned to hazard-detection and security-detection equipment.

The vendor's customer footprint is heavily concentrated in Department of Homeland Security programs. The Transportation Security Administration dominates both volume and dollar value, accounting for 271 of 975 total awards (28% of the award count) with $5.09 billion in combined potential value—roughly 87% of the company's entire federal portfolio. DHS Countering Weapons of Mass Destruction follows distantly with 11 awards ($344.5 million), while Immigration and Customs Enforcement (30 awards, $174 thousand) and the Department of State (31 awards, $207 thousand) represent lower-dollar maintenance and service work. This concentration reflects Leidos' position as TSA's primary vendor for explosive detection system procurement, installation, and sustainment.

Leidos Security Detection & Automation holds two major indefinite delivery contracts with TSA: a $363 million single-award IDIQ for Explosive Detection Systems Type 1 and Type 2, awarded September 12, 2025, running through September 11, 2032, and a $115.8 million single-award IDIQ for security screening and detection systems, awarded September 6, 2023, running through September 5, 2030. The larger contract anchors recent delivery orders including a $20.33 million award (September 27, 2024) for 17 medium-speed explosive detection systems, a $19.72 million award (May 28, 2024) for medium and reduced-size EDS purchase and installation at Tewksbury, and a $12.99 million award (September 22, 2025) for MSEDS and RSEDS with installation services in Springfield, Virginia. The smaller IDV supports algorithm deployment, software upgrades, and system management; recent task orders include a $19.59 million delivery order (September 12, 2023) for Leidos STSS System Management Services in Vienna, Virginia, extending through September 11, 2030. Beyond TSA IDIQs, Leidos operates under multiple other TSA task-order vehicles including Medium Speed Explosive Detection System (84 task orders, $283.2 million) and Advanced Imaging Technology 2nd Generation (17 task orders, $70.3 million). The company also holds positions on DHS CWMD IDCs: a $27.43 million delivery order (September 20, 2021) for radiation portal monitor installation with subcontractors Symetrica Inc. and Landstar Inway, Inc., and a $1.40 million order (December 3, 2021) for RPM replacement at ports of entry, with sub-work to Symetrica.

Activity has been variable but remains substantial. Award volume was 13 in 2022, declining to 10 in 2023, recovering to 14 in 2024, then dropping to 8 in 2025 and 6 in 2026 year-to-date. The recompete cliff presents meaningful near-term exposure: 11 awards with combined potential value of $43.8 million face ultimate completion within the next twenty-four months. SCI-reported invoicing (covering federal service contracts above $150,000) totaled $22.8 million across FY2022–FY2024, declining from $14.8 million in FY2022 to $2.8 million in FY2024 across 0.9, 14.1, and 6.0 FTEs respectively in those years. On federal services contracts captured in SCI, government-paid rates ranged from a 10th-percentile floor of $136.01/hr through a median of $239.36/hr to a 90th-percentile ceiling of $2,325.47/hr, reflecting a mix of field technician and senior engineering labor. The company self-performs substantially all reported prime-contract labor; across SCI-reportable prime contracts, subcontractors accounted for 1% of total contractor hours, with one named subcontractor identified.

Leidos Security Detection & Automation operates predominantly as a prime contractor delivering its own labor and equipment. In its limited subcontractor footprint, the company subs to Science Applications International Corporation on defense IT infrastructure support (Federal Lands IT, IMDC2 technical support, and Volpe infrastructure services) and to PAE Government Services, Inc., on international aviation security training under State Department ICITAP programs. The company manufactures and sells detection equipment alongside installation, integration, testing, training, warranty, and field maintenance services—a vertically integrated model that limits reliance on external supply partners. Named subcontractors on prime TSA and CWMD awards (Symetrica Inc., a radiation detection manufacturer, and Landstar logistics) are equipment or logistics partners rather than service labor subcontractors.
