Electronics Service, Inc.

Electronics Service, Inc., doing business as Engineering/Electronics Service, is a Service-Disabled Veteran-Owned Small Business based in Great Mills, Maryland, that manufactures electromagnetic testing and protective equipment and delivers electromagnetic environmental effects (E3) engineering, testing, and consulting services to the Department of the Navy and the Department of Defense as a prime contractor on multiple-award indefinite-delivery contracts and as a subcontractor to large defense primes. The vendor operates as both a prime (43% of recent awards) and subcontractor (57%), with the bulk of its dollar potential anchored to naval programs.

Electronics Service, Inc. is a for-profit Subchapter S corporation and veteran-owned manufacturer with a concrete capability portfolio in electromagnetic pulse and electromagnetic interference protection, design, testing, repair, and consulting. The vendor's core work centers on electromagnetic systems integration, high-altitude electromagnetic pulse (HEMP) testing and analysis, shipboard bonding and grounding, lab research and development, and rapid electromagnetic interference diagnosis and mitigation. Representative prime work includes a $4 billion multiple-award indefinite-delivery contract with Naval Sea Systems Command under Seaport Next Generation (awarded January 2, 2025, with ultimate completion January 1, 2029), which contemplates electromagnetic protection and shielding solutions across naval weapon systems; a $151 billion multiple-award indefinite-delivery contract with the Missile Defense Agency under the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program (awarded December 29, 2025, with performance through December 28, 2035), where the vendor's E3 engineering is expected to support layered defense across air, missile, space, and cyber domains; and a $1 million Federal Supply Schedule contract with GSA's Federal Acquisition Service (awarded January 23, 2025, through January 22, 2030) offering nationwide and international E3 systems integration and HEMP testing services across six labor categories. The vendor also holds a sole-source purchase order from Naval Sea Systems Command for an Electronic Pulser, part number 401-P ES 400 Series, valued at $82,262.84 (awarded July 26, 2024).

Customer concentration is extreme: the Department of the Navy's Naval Sea Systems Command accounts for 6 awards and the full $4 billion in combined potential value (93% of total awards by count, 100% by potential value). The Missile Defense Agency contributes 2 awards valued at $500 combined potential value; GSA Federal Acquisition Service contributes 1 award valued at $1 million. The Naval Air Systems Command Naval Air Warfare Center and the Naval Information Warfare Systems Command each hold 2 awards with no dollar ceiling stated in the source.

On prime indefinite-delivery vehicles, Electronics Service, Inc. sits on Seaport Next Generation (5 task orders, $500 combined potential value) and SHIELD (1 task order, $500 combined potential value). As a subcontractor, the vendor delivers E3 systems engineering, test and evaluation support, and electromagnetic testing services to General Dynamics Information Technology (E3 test, evaluation, and range services for C4ISR systems; electromagnetic effects division electromagnetic testing and engineering support), Lockheed Martin (LCS 29 platform design, test, and training support for EMI corrections), Amentum Services (engineering support, risk identification, and characterization and analysis), KBR Wyle Services (E3 systems engineering and test and evaluation support), and Booz Allen Hamilton (Naval Surface Warfare Center electromagnetic testing and engineering support). The vendor also served as a sub-recipient under the National Center for Manufacturing Sciences on a federal grant for rapid electromagnetic interference diagnosis and mitigation (awarded March 17, 2024).

On the GSA Multiple Award Schedule, the vendor prices six labor categories spanning entry-level E3 engineer roles at $74 per hour through senior engineer and subject-matter-expert roles ranging to $240 per hour; all positions require bachelor's-level education or equivalent experience and no security clearance. Activity has accelerated from five awards in 2024 to eight in 2025, with only one award recorded in 2026 to date. Service Contract Inventory data shows minimal sub-engagement (5 SCI records as subcontractor across FY2022–FY2025, with FTE trajectory of 1.3 in FY2022, declining to 0.4 in FY2024, then recovering to 6.0 in FY2025), reflecting the vendor's primary reliance on prime and IDC work rather than commercial-services delivery to federal agencies. Combined obligated dollars across all awards total $9 million against $4 billion in combined potential value, indicating that the SHIELD and Seaport indefinite-delivery vehicles are not yet heavily tasked.
