Maccor Inc.

Maccor Inc., a Tulsa, Oklahoma–based for-profit Subchapter S corporation, manufactures and services automated battery test systems and related diagnostic equipment for the Department of Defense and Army research organizations, competing as a prime contractor on full-and-open purchase orders with no recurring set-aside posture. The company operates almost entirely as a prime (98% of awards), with minimal subcontract engagement, and specializes in advanced battery and cell test equipment under NAICS 541512 (Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals).

Maccor's customer base is heavily concentrated in naval and Army research and logistics commands. The top five customers by award count account for 69% of all awards, anchored by Naval Sea Systems Command (17 awards, $621 thousand combined potential value) and Army Materiel Command Research Development and Engineering Command (RDEC) (17 awards, $1.4 million), followed by the Office of Naval Research (11 awards, $726 thousand), Army Materiel Command (6 awards), and Naval Supply Systems Command Engineering Logistics Office (5 awards, $122 thousand). The ranking by potential value shifts slightly — RDEC dominates dollars at $1.4 million across 17 awards — but the core customer concentration remains Navy and Army research labs. Over the past thirty years, Maccor has served 21 distinct customer agencies.

Maccor's award footprint consists almost entirely of small purchase orders for battery test systems and maintenance services. Recent representative work includes a $186.8 thousand Total Small Business purchase order from the Office of Naval Research (April 2025) for an automated test system high-powered cycler destined for Naval Research Laboratory; a $155.9 thousand sole-source award from Naval Supply Systems Command (January 2024) for a MACCOR 4000 Battery Test System integrated into the Naval Surface Warfare Center Crane program; a $129.1 thousand sole-source award from Army Materiel Command RDEC (August 2024) for delivery of a Series 4000H Battery Test System to Army Research Laboratory in Adelphi, Maryland; and a $126.7 thousand purchase order from the Office of Naval Research (August 2025) for battery performance testing equipment and a coupled temperature chamber. The company also delivers maintenance, calibration, and equipment upgrade services — such as thermocouple integration into existing MACCOR Series 4200M test units (Naval Air Warfare Center, June 2025, $15.5 thousand).

Activity has remained modest and relatively flat, averaging three to five awards annually over the past five years, with combined potential value across all 81 awards totaling $3.7 million (actual obligated dollars $4.6 million). Two subcontract engagements appear in the source: a Materials subcontract under Johns Hopkins University Applied Physics Laboratory for the Dragonfly Extended Phase B mission (January 2026) and a test equipment subcontract under Valkyrie Enterprises for MIT Lincoln Laboratory research and development (August 2024). Maccor does not occupy government-wide acquisition vehicles; its two named indefinite-delivery contracts each carry only one task order. The company's product portfolio centers on the MACCOR Series 4000H, 4200M, and 4300 Automated Test Systems, which function as specialized, sole-source solutions in naval and Army research environments where integration with existing programs creates switching costs that favor reorder and maintenance revenue.
