About D & W Marine Systems Management Inc.
D & W Marine Systems Management Inc., doing business as D & W, is a service-disabled veteran-owned small business (SDVOSB) and self-certified small disadvantaged business that supplies specialized maritime equipment and electrical components to the Defense Department as a prime contractor on purchase orders and indefinite-delivery contracts. The vendor operates as a Subchapter S Corporation headquartered in Gravette, Arkansas, and competes across both set-aside and full-and-open vehicles, though the majority of its recent work (approximately 58% of awards) carries set-aside designations including Total Small Business, Service-Disabled Veteran-Owned Small Business, and SDVOSB single-source awards.
D & W's capability portfolio centers on maritime and electrical components—solenoid valves, circuit breakers, electromagnet relays, lightning arresters, switches, connectors, pumps, gears, and related valve assemblies—sourced and delivered to Department of Defense depots and distribution centers. The vendor's work spans industrial valve manufacturing (209 awards, NAICS 332911), relay and industrial control manufacturing, and electronic component distribution. Representative prime contracts include a $139.8 million firm fixed-price purchase order from Defense Logistics Agency Land and Maritime (awarded November 2023) for sensitive switches; a $120.6 million order from Naval Supply Systems Command (March 2024) for valve repair kits; and a $174.7 thousand contract from Naval Supply Systems Command (March 2023) for rotary valves. Recent orders reflect sustained demand: a $46.7 thousand audio amplifier purchase order (August 2024) and a $36.4 thousand solenoid parts kit order (January 2026), both from DLA Land and Maritime.
Customer concentration is extreme: Defense Logistics Agency Land and Maritime accounts for 467 of 513 total awards and $18.6 million of the $21.6 million combined potential value, representing 91% of dollars. The remaining customer base—Department of the Navy Naval Supply Systems Command (15 awards, $927 thousand), Defense Logistics Agency Aviation (14 awards, $232 thousand), Defense Logistics Agency Troop Support Construction and Equipment (11 awards, $170 thousand), and Naval Sea Systems Command (4 awards, $135 thousand)—adds marginal volume. One outlier: a $1.5 million award from the Department of the Air Force United States Air Forces in Europe - Air Forces Africa (not separately detailed in the award listing).
D & W holds multiple single-award indefinite-delivery contracts (IDCs) with DLA Land and Maritime, each valued up to $250,000, spanning solenoid valves, parts kits, electromagnet relays, switches, connector plugs, circuit breakers, worm gears, lightning arresters, and gaskets. The vendor also maintains a position on the Department of the Navy's Seaport Next Generation (SeaPort-NXG) multiple award contract vehicle, valued at up to $500 million, for program management, engineering, technical, and logistics support services across 23 functional areas. The top parent IDCs by task order count include SPE7M520D61JW (7 orders, $39 thousand), SPE7M522D60MN (7 orders, ceiling not specified), and SPE7M521D60PW (6 orders, $6 thousand).
Activity has declined sharply: 113 awards in FY2022 fell to 49 in FY2024, 17 in FY2025, and 9 in FY2026 through mid-April. Four awards totaling $1.5 million in combined potential value complete within the next twenty-four months, representing moderate recompete exposure. Service Contract Inventory reports minimal activity—6 SCI records spanning FY2022–FY2024, all as named subcontractor, totaling approximately 4.7 FTEs annually. This reflects D & W's posture as a product supplier rather than a labor-intensive services prime; SCI captures only service contracts above the $150,000 threshold and excludes goods procurement, which dominates D & W's footprint.
D & W operates almost entirely as a prime contractor (511 of 513 awards). Sub-award activity is negligible: two subcontract positions (both minor) appear under Atlantic Diving Supply, Inc. (data surge protector, May 2024) and Sayres and Associates LLC (program management and logistics support for Navy PMS 325, March 2024). The vendor neither reports significant subcontractor engagement nor builds delivery teams; instead, it sources and fulfills individual purchase orders and IDC call orders for discrete maritime equipment items, with all work performed at its Gravette facility.
