Ets-Lindgren Inc.

ETS Lindgren Inc., a wholly owned division of Esco Technologies Inc., manufactures electromagnetic shielding systems, radio frequency test chambers, radar absorbent materials, and specialized anechoic chamber infrastructure for federal agencies as a prime contractor (88% of recent awards), competing exclusively in full-and-open procurements without SBA set-asides. The company is headquartered in Wood Dale, Illinois, with operational facilities supporting electromagnetic compatibility testing, RF shielding installation, and MRI facility maintenance across the continental United States and at federal test ranges.

ETS Lindgren's customer base spans ninety distinct federal agencies, but concentration clusters heavily in defense infrastructure and specialized testing. The top customer by potential value is the Department of the Army Materiel Command's Research Development and Engineering Command, which anchors $20.9 million across nine awards — predominantly radar absorbent material procurement and installation at White Sands Missile Range. The Department of the Army Test and Evaluation Command follows with sixteen awards worth $5.8 million, primarily for absorber materials and anechoic chamber infrastructure. The Department of State (Bureau of Overseas Building Operations and Department of State proper) collectively accounts for thirty-four to fifty-two awards representing $1.6 million in combined potential value, focused on RF-shielded enclosure installation and maintenance at diplomatic facilities worldwide. The Department of the Navy (Naval Sea Systems Command and Naval Air Warfare Center) holds nineteen awards valued at $702 thousand for anechoic chamber revitalization, chamber door repairs, and RF measurement equipment. The Department of Veterans Affairs drives recurring MRI door and waveguide maintenance work across its regional healthcare system. The Department of Defense, Department of Homeland Security (Immigration and Customs Enforcement), Federal Emergency Management Agency, Federal Communications Commission, and health agencies (National Heart Lung and Blood Institute, Defense Health Agency, National Eye Institute) complete the active set.

Two significant IDIQs anchor ETS Lindgren's prime contract vehicle position. A $15 million single-award indefinite-delivery contract with the Research Development and Engineering Command for radar absorbent material procurement runs through September 2029, with two delivery orders issued to date totaling $3.9 million for RAM installation and removal at White Sands. A second $82 thousand single-award IDIQ with Veterans Integrated Service Network 4 for MRI door and waveguide maintenance through September 2029 carries four delivery orders worth $51.2 thousand. The company also places work against navy-wide IDICs (N6247318D5853 with ten task orders and FA821421D0002 with nine task orders) and air force acquisition vehicles, though specific dollar ceilings and customer names are masked in the parent-vehicle summary. Recent prime work includes a $2.1 million Army delivery order for radar absorbent material installation at White Sands (June 2025), a $578 thousand Air Force Academy order for anechoic chamber modernization in Fairchild Hall (January 2026), a $484.8 thousand State Department order for RF shielding at Springfield, Virginia (January 2025), a $1.2 million Federal Emergency Management Agency order for twenty-five electromagnetic pulse-protected enclosures (July 2023), and a $254.7 thousand Naval Sea Systems Command order for anechoic chamber revitalization at Naval Surface Warfare Center Panama City (May 2024). Category concentration runs heavily to instrument manufacturing for measuring and testing electricity and electrical signals (ninety-five awards) and repair/maintenance of electronic and precision equipment (fifty awards), with substantial construction-support work (fifteen awards) reflecting chamber installation and facility modification scopes.

ETS Lindgren also serves as a named subcontractor to tier-one systems integrators on defense test and integration programs. Recent sub work includes instrument manufacturing and RF/electromagnetic compatibility testing support to Northrop Grumman Systems Corporation on Ground Subsystem Support Contract 2.0 sustainment task orders (seven sub-awards, 2024–2025), RF-shielded enclosure and calibration services to BAE Systems Technology Solutions on the Instrumentation Range Support Program III (two sub-awards, 2024–2025), environmental test and calibration support to Peraton Inc. on the ETIS III contract with NASA Goddard Space Flight Center (April 2025), EMC testing support to Booz Allen Hamilton on EMAPS 2 (March 2025), and logistics and classified system installation services to Alutiiq Information Management on State Department worldwide maintenance programs (six sub-awards, 2023–2025). Additional sub engagement includes work for Honeywell Federal Manufacturing & Technologies on Department of Energy National Security Campus operations and for General Dynamics Information Technology on global security engineering and supply chain services. SCI reporting captures minimal ETS Lindgren activity — four sub-contractor records across FY2022–FY2025 with a combined 0.2 FTEs, indicating the company's federal services work is dominated by product delivery (absorber materials, RF enclosures, test equipment, door systems, and installation labor) rather than time-and-materials staffing engagements above the $150 thousand SCI reporting floor.

Activity has accelerated in recent years, rising from eleven awards in 2022 and twelve in 2023 to thirty-three in 2024, with eighteen awards recorded in 2025 and seven through late September 2026. The recompete cliff is minimal — only three awards (combined potential value $2.1 million) reach ultimate completion within the next twenty-four months, limiting near-term recompete exposure and suggesting stable contract renewal likelihood for the MRI maintenance IDIQs and Army RAM procurement vehicle. ETS Lindgren holds no notable exclusive vendor relationships, competes openly against established EMC infrastructure firms such as Frankonia and TDK Lambda on chamber modernization work, and functions as a specialized original-equipment manufacturer supplier to larger defense contractors. The company's subsidiary standing under Esco Technologies Inc. (a publicly traded diversified manufacturer and technology services conglomerate) provides access to corporate-level capital and supply-chain resources but operates independently in federal business development.
