Dumbo Defense Inc.

Dumbo Defense Inc., a for-profit Subchapter S corporation headquartered in Brooklyn, New York, manufactures specialized military components and equipment as a prime contractor (98% of recent awards) on indefinite delivery contracts and purchase orders across Defense Logistics Agency divisions and Naval commands. The company is a small business with no SBA certifications beyond basic small business status and competes across both full-and-open and small business set-aside categories, with roughly equal distribution between the two postures.

Dumbo Defense's capability portfolio centers on specialized military logistics components: torpedo maintenance kits, hermetic sealing cans, signal horns, liquid samplers, decontamination kits, tail rotor strips for aircraft, fire control equipment, canvas tents, canvas repair kits, oil sampling kits, computer navigation systems, laboratory burets, and related mechanical and electronic assemblies for weapon systems and military equipment maintenance. Recent representative prime work includes a $1.007 billion definitive contract from Naval Supply Systems Command in June 2025 for seawater-activated batteries (TU44); a $591.6 thousand contract from TACOM Life Cycle Management Command in February 2025 for hydraulic accumulators under small business set-aside; and a $315 thousand purchase order from DLA Aviation in May 2025 for tail rotor strips. The company also holds a $4 billion multiple-award SeaPort-NXG contract with Naval Sea Systems Command through January 2029, carrying a $500 minimum guarantee order awarded in March 2025.

Customer concentration is extreme and defense-dominated. DLA Aviation accounts for 224 awards (38% of prime awards) with $10.5 million combined potential value; DLA Land and Maritime holds 127 awards with $6 million; and DLA Troop Support Construction and Equipment represents 103 awards with $3 million. Naval Supply Systems Command placed 41 awards worth $3.7 million. Together these five customers account for 97% of award count but only 0.3% of combined potential value because the Naval Sea Systems Command SeaPort-NXG contract ($4 billion of the $4.03 billion portfolio total) dominates the dollar ranking despite representing just two awards. DLA Aviation and Land and Maritime rank consistently high in both volume and dollars, while Naval Sea Systems Command anchors the portfolio value. This divergence signals a mature, high-volume small-purchase operation (hundreds of discrete task orders under $350 thousand IDCs) alongside a strategic enterprise-scale vehicle.

Dumbo Defense holds multiple single-award indefinite delivery contracts: a $1.999 billion ceiling with DLA Aviation for tail rotor strips (small business set-aside through May 2030); a $1.489 million ceiling with Naval Supply Systems Command for torpedo maintenance kits and related components (small business set-aside through August 2029); five additional DLA Aviation IDCs valued at $250 thousand to $350 thousand; and single-award agreements with DLA Land and Maritime for loudspeakers ($350 thousand through March 2027). The five highest-volume parent vehicles are unnamed DLA Aviation indefinite delivery contracts (SPE4A622D5575, SPE4A622D5444, SPE4A622D5877, SPE4A723D5442, SPE4A624D5071) collectively carrying 69 task orders with roughly $380 thousand combined potential value—typical of Dumbo Defense's operating model of frequent, small-dollar task-order execution.

Activity has remained flat to declining: 93 awards in 2022, peaking at 164 in 2024, then dropping to 137 in 2025 and 49 through mid-October 2026. Only five awards face ultimate completion within the next twenty-four months with combined potential value of $328 thousand—minimal recompete cliff exposure, indicating the vendor's portfolio is long-tailed and renewal-focused rather than execution-heavy. In its subcontractor role, Dumbo Defense performs battle damage assessment and repair (BDAR) kit materials integration for Science and Engineering Services LLC under an Aviation Mission Systems and Architecture IPO requirement, and supplies medical/surgical equipment to Cardinal Health 200 LLC under regional medical supply contracts—representing 2% of the footprint.

Dumbo Defense's subsidiary, Dresser-Argus, Inc., is listed as a for-profit manufacturer of goods but appears inactive in the recent award record. The vendor corporate structure suggests potential diversification or legacy holdover without active federal contracting integration in the visible period. Dumbo Defense registers as a standard for-profit manufacturer competing across DLA Aviation, Land and Maritime, and Construction and Equipment divisions for standardized military logistics components, with primary strength in laboratory and navigational instruments, mechanical motion sensors, drums and cans, and aeronautical systems components. The $4 billion SeaPort-NXG seat represents the vendor's primary strategic contract; the remainder of the portfolio comprises routine small-business-set-aside and full-and-open purchase orders typical of defense supply chain participation.
