Marine Air Supply Co., Inc.

Marine Air Supply Co., Inc., doing business as Marine Air Supply Co Inc., is a woman-owned small business based in Frederick, Maryland, that supplies electro-mechanical components and aviation parts to the Department of Defense as a prime contractor on purchase orders and indefinite delivery contracts, competing predominantly on full-and-open procurement actions without set-aside restrictions though holding several total small business set-aside awards.

The company specializes in mission-critical electronic hardware components including toggle switches, push button switches, circuit breakers, sensitive switches, indicator lights, electromagnetic relays, and related electro-mechanical assemblies. Representative work spans commodity component procurement for defense logistics: a $351 thousand purchase order from Defense Logistics Agency Land and Maritime for switch assemblies (NSN 5930013918430, total small business set-aside, April 2025); a $236 thousand delivery order for light assembly indicator components from DLA Aviation (December 2025); a $175 thousand purchase order for electromagnetic relays from DLA Land and Maritime under total small business set-aside (November 2025); and a $137 thousand delivery order for toggle switches from DLA Land and Maritime (April 2025). The company has registered in the System for Award Management since April 2002 and maintains a portfolio of single-award indefinite delivery contracts with the Defense Logistics Agency, each carrying a ceiling of $250,000 to $350,000 with estimated order frequencies of 4 to 12 orders annually.

Customer concentration is extreme. Defense Logistics Agency Land and Maritime accounts for 4,420 awards (69% of the footprint) valued at $83.4 million combined potential value, followed by Defense Logistics Agency Aviation with 1,474 awards valued at $16.3 million. Together, the two DLA divisions represent 97% of Marine Air Supply's recent award count and 98% of combined potential value. The Navy's Naval Supply Systems Command and DLA Troop Support construction, equipment, and hardware divisions account for the remaining activity but at negligible scale.

Marine Air Supply holds a portfolio of single-award indefinite delivery contracts issued by DLA Land and Maritime and Aviation, including vehicles awarded April 2026 ($350 thousand, circuit breakers), March 2026 ($350 thousand, circuit breakers, total small business set-aside), March 2026 ($350 thousand, circuit breakers), February 2026 ($350 thousand, various electro-mechanical components), and five additional $250 thousand IDCs awarded between May and October 2025 covering toggle switches, circuit breakers, and sensitive switches. The largest parent vehicle by task-order count is Indefinite Delivery Contract SPE7MX21D0017 (115 task orders, $4.5 million), suggesting a legacy DLA ordering vehicle, while more recent awards are structured as individual single-award IDIQ contracts.

Activity has declined significantly. The company received 666 awards in 2022, declining to 419 in 2023, 357 in 2024, 227 in 2025, and 41 awards through mid-2026, a trend reflecting both tightening of DLA commodity procurement and potential customer consolidation. Approximately 148 awards carrying combined potential value of $3.2 million reach ultimate completion within the next twenty-four months, representing recompete exposure across toggles, push buttons, circuit breakers, relays, and indicator lights.

Marine Air Supply's subcontractor footprint is minimal. The source identifies one named sub-award: an August 2024 sub to BAE Systems Land & Armaments L.P. for M88A2 production material under FY23 modification, suggesting the company operates almost exclusively as a prime. NAICS concentration is tight: 2,976 awards in Other Electronic Component Manufacturing (334419), 557 in Switchgear and Switchboard Apparatus Manufacturing (335313), and 306 in Semiconductor and Related Device Manufacturing. Product Service Code concentration is tighter: 3,650 awards for switches, 1,087 for indoor and outdoor lighting fixtures, 456 for circuit breakers, 326 for vehicular lights and fixtures, and 143 for relays and solenoids. The vendor delivers to Defense Logistics Agency depots across the continental United States and overseas consolidation and containerization points, with typical delivery windows of 39 to 168 days after order placement.
