About the company

Dayton T. Brown, Inc., a for-profit manufacturer and technical services provider based in Bohemia, New York, holds a diversified prime contract portfolio spanning environmental testing, engineering analyses, specialized aerospace and defense component manufacturing, technical documentation, and logistics support across 57 federal agencies, with recent activity concentrated in the Department of the Air Force, Naval Sea Systems Command, and Naval Air Warfare Center. The vendor operates as a prime contractor on 97% of its awards and competes full-and-open with no set-aside designations; the company's $64.1 billion combined potential value across 1,770 awards reflects its positioned strength on multiple billion-dollar IDIQs rather than a large invoiced revenue base (obligated value is $471.5 million, or 1% of potential).

Dayton T. Brown's recent contract wins anchor to three mega-vehicles awarded within the past twelve months: a $151 billion Missile Defense Agency Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ (awarded December 29, 2025, running through December 28, 2035), a $46 billion Air Force Lifecycle Management Center Eglin Wide Agile Acquisition Contract (EWAAC) On-Ramp IV vehicle (awarded March 13, 2025, running through September 9, 2031), and the existing $4 billion Naval Sea Systems Command SEAPORT-NXG indefinite delivery contract (awarded January 2, 2025, running through January 2029). These three vehicles alone account for the overwhelming majority of the vendor's potential-value posture and position Dayton T. Brown as a qualified technical services provider across multi-domain defense modernization, air vehicle sustainment, and naval engineering programs. Beyond these mega-IDIQs, the vendor holds a $249 million Basic Ordering Agreement with Naval Air Warfare Center for technical and engineering support (awarded August 4, 2023, running through May 31, 2028), a $9 million Blanket Purchase Agreement with Naval Air Warfare Center (awarded December 12, 2024, running through December 15, 2029), a $6.39 million DLA Land and Maritime indefinite delivery contract for miscellaneous goods and services (May 2028 expiration), a $2.1 million Naval Supply Systems Command engineering and testing IDC (running through January 7, 2029), and a $4.5 million Federal Railroad Administration blanket purchase agreement for Positive Train Control Safety Plan reviews (running through September 26, 2026).

Customer concentration by potential value is driven almost entirely by the Air Force ($46 billion) and Navy strategic vehicles; Naval Sea Systems Command, Naval Air Systems Command/Naval Air Warfare Center, and DLA Land and Maritime together represent over $18 billion in combined potential value, but only 612 of 1,770 total awards. By award count, the ranking shifts: the Department of the Navy leads with 508 awards (38% of all awards), followed by DLA Land and Maritime with 424 awards (30% of all awards). The top-five funding agencies account for approximately 70% of award count but a vastly higher share of potential dollars owing to the concentration in mega-vehicle holdership. Dayton T. Brown's activity trajectory shows steady award volume across recent years—49 awards in 2022, 42 in 2023, 66 in 2024, and 70 in 2025—with eight awards recorded in 2026 year-to-date; the large potential-value figures mask that most individual awards are small delivery orders, with 25 awards (combined potential value $106.8 million) reaching completion within the next twenty-four months and facing recompete risk.

Dayton T. Brown's named vehicle position spans DLA-administered indefinite delivery contracts (SPE7MX18D0095 with 172 task orders valued at $3.1 million, and SPE7MX23D0065 with 83 task orders at $1.3 million), Navy-wide vehicles (SEAPORT-NXG, SHIELD, the Naval Air Warfare Center BOA and BPA), and smaller agency-specific IDCs and BPAs. The vendor's subcontractor footprint names Boeing, Lockheed Martin, RTX, General Electric, Sikorsky Aircraft, Sierra Nevada, BAE Systems, and other major defense primes across aerospace support, engineering, testing, technical publications, and logistics functions; sub-awards dated 2024–2025 include aerospace physiology and performance research (windblast testing), engine engineering support, electromagnetic interference and TEMPEST testing, aircraft parts and service, and technical manual development for platforms including the E-6B, AH-64, UH-60M Black Hawk, and F-35 derivatives.

Dayton T. Brown's award history reflects a 60-year-old company with deep roots in defense environmental testing and specialized manufacturing. The vendor competes across testing laboratories and services (441 awards), aircraft parts and auxiliary equipment manufacturing (84 awards), engineering services (66 awards), and related NAICS categories; top PSC codes align with hardware, equipment and materials testing, aircraft components, and professional engineering support. The company's core service delivery spans cost-plus-fixed-fee task orders under Navy vehicle ceilings, firm fixed-price delivery orders under DLA IDCs, time-and-materials orders for railroad safety assessments under FRA's BPA, and specialized manufacturing and testing work for Air Force Materiel Command and other service branches. Place of performance is Bohemia, New York for the majority of work, with subordinate locations including Patuxent River, Maryland (Naval Air Warfare Center), Wright-Patterson Air Force Base, Ohio (EMI and windblast testing), San Diego, California (engineering), and Huntsville, Alabama (SHIELD performance).
