Ets-Lindgren Inc.

ETS Lindgren Inc., a subsidiary of Esco Technologies Inc. headquartered in Wood Dale, Illinois, manufactures electromagnetic shielding systems, radio frequency test chambers, radar absorbent materials (RAM), and specialized anechoic chamber infrastructure for federal agencies as a prime contractor (88% of recent awards). The company competes exclusively in full-and-open procurements with no set-aside designations and no SBA certifications; its customer base spans 88 distinct federal agencies, though concentration is steep and concentrated in defense and research applications.

ETS Lindgren's capability portfolio centers on RF-shielded enclosures, MRI door and waveguide maintenance, anechoic chamber modernization, absorber material procurement and installation, and probe calibration services. Representative prime work includes a $2.079 million firm fixed-price delivery order from the Army Research Development and Engineering Command (June 2025) for installation of new radar absorbent material and removal of existing material at the large anechoic chamber at White Sands Missile Range; a $578 thousand firm fixed-price purchase order from the Air Force Academy (January 2026) for modernization of an anechoic chamber at Fairchild Hall involving replacement of foam absorbers and installation of high-performance absorbers with 25-year service life across 10 MHz to 40 GHz; and an $82 thousand single-award IDIQ with the Department of Veterans Affairs Veterans Integrated Service Network 4 (September 2024) for MRI door and waveguide maintenance and repair, with delivery orders placed through September 2029. Across the portfolio, ETS Lindgren holds two significant IDIQ vehicles: a $15 million indefinite delivery contract with the Army Materiel Command Research Development and Engineering Command (September 2024) for radar absorbent material procurement supporting White Sands operations through September 2029, and a smaller $82 thousand VA IDIQ running through the same period.

Customer concentration is dominated by defense and infrastructure customers. The Department of the Army Materiel Command Research Development and Engineering Command anchors 58% of combined potential value across nine awards ($20.9 million), reflecting ETS Lindgren's specialized role as the preferred supplier for White Sands Missile Range electromagnetic testing infrastructure. The Department of the Army Test and Evaluation Command places the second-largest concentration at 16 awards worth $5.8 million. The Department of State Bureau of Overseas Building Operations accounts for 18 awards ($1.6 million), and the Naval Sea Systems Command and Naval Air Warfare Center place work across multiple purchase orders for chamber maintenance and RF equipment. By award count, the Department of State broadly (34 awards) leads, but this volume masks the dollar concentration at DoD and DoA test ranges.

Activity has grown materially: 11 awards in 2022, 12 in 2023, 33 in 2024, then moderating to 18 in 2025 and 4 (so far) in 2026. The recompete cliff is modest — only four awards worth $2.8 million combined have ultimate completion dates in the next twenty-four months, presenting limited near-term recompete exposure. The company holds positions on multiple indefinite delivery vehicles, including two large Navy IDIQs (N6247318D5853 with 10 task orders and FA821421D0002 with 9 task orders) and an Army IDC (19AQMM20D0112 with 5 task orders).

ETS Lindgren subcontracts at scale across defense prime contractors. Recent named sub relationships include work for Northrop Grumman Systems Corporation on Ground Subsystem Support Contract (GSSC) 2.0 general sustainment task orders (multiple 2024–2025 awards) delivering instrument manufacturing for measuring and testing electrical signals; Honeywell Federal Manufacturing & Technologies on management and operation of the National Security Campus; BAE Systems Technology Solutions & Services on the Instrumentation Range Support Program III; and Peraton on the ETIS III environmental test and integration contract for NASA Goddard Space Flight Center. Named sub awards span test equipment, antennas, connectors, RF and EMC testing capability, and design and verification testing on facility construction programs. SCI reporting is minimal — only 3 service-contract records across FY2022–FY2024, all as named subcontractor with roughly 0.1 FTEs shown in each period — indicating that ETS Lindgren's federal footprint is dominated by product sales and installation labor on fixed-price purchase orders and delivery orders rather than time-and-materials service contracts.

The vendor's NAICS concentration is heavy on precision instruments: Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals (NAICS 334515) carries 95 awards, with secondary volume in Other Electronic and Precision Equipment Repair and Maintenance (NAICS 811219, 50 awards). PSC-level concentration mirrors this profile — Electrical And Electronic Properties Measuring And Testing Instruments (22 awards), Laboratory Equipment And Supplies (20 awards), and Maintenance/Repair/Rebuild of Equipment–Instruments and Laboratory Equipment (20 awards) dominate. Across the portfolio, ETS Lindgren operates as an original equipment manufacturer and authorized service provider for electromagnetic testing infrastructure, with long-standing relationships at DoD test ranges (White Sands, Dahlgren, Ridgecrest, Panama City) and federal research facilities. The company is not a volume prime on government-wide contract vehicles or civilian technology schedules; instead, it wins focused, often sole-source or limited-competition awards from agencies with specialized electromagnetic testing requirements.
