About the company

Science And Engineering Services, LLC, a minority-owned, Asian-Pacific American-owned manufacturer based in Huntsville, Alabama, delivers aviation components, aircraft modifications, logistics support, and engineering services to the Department of Defense and related federal agencies as a prime contractor (99% of recent awards) and occasional subcontractor. The company competes predominantly in full-and-open procurement without set-aside restrictions, though it holds minority-owned status and appears in Total Small Business set-asides on select orders.

The vendor's portfolio is heavily concentrated in defense aviation. Top customers by combined potential value include Naval Air Systems Command ($15.46 billion on 15 awards plus an additional $6.22 billion across 10 separate awards), the Army's PEO Aviation ($5.75 billion across 177 awards), and the Army Materiel Command's Aviation and Missile Life Cycle Management Command ($2.22 billion across 166 awards). These five customer streams account for 93% of the vendor's combined potential value. The concentration is even more pronounced by award count: PEO Aviation and AMCOM together represent 343 of 556 total awards (62%). Defense Logistics Agency Aviation rounds out the top tier with 119 smaller-dollar orders yielding $16.6 million combined potential value. The vendor serves 20 distinct federal agencies in total, but activity is sharply weighted toward Army and Navy aviation programs.

Representative prime work includes a $8.19 million delivery order from PEO Aviation (awarded September 2024) for Battle Damage Assessment and Repair kit procurement, integration, and kitting; a $71.1 million Naval Air Warfare Center order (August 2024) for storage and funding support of the CACTUS requirement; a $21.86 million Army PEO Intelligence Electronic Warfare & Sensors order (March 2023) for H-60M Common Infrared Countermeasure A-kits; and a $56.99 million Customs and Border Protection delivery order (September 2025) for multirole enforcement aircraft, training, and spares. On the smaller end, Science And Engineering Services regularly receives task orders under standing IDIQs for individual aviation components—aircraft fairings, structural brackets, insulation blankets, cable assemblies, seat assemblies, and control panels—ranging from under $10,000 to several hundred thousand dollars per order.

Science And Engineering Services holds positions on five major parent vehicles. The two largest—both Army-managed indefinite delivery contracts—are the backbone of its federal footprint: W58RGZ09D0130 (182 task orders, $1.31 billion combined potential) and W58RGZ13D0048 (133 task orders, $1.28 billion combined potential). The Aviation System Modification Support 2019 IDIQ carries 53 task orders worth $403.4 million. The Air Force's Support Equipment Vehicles Strategic Replenishment Contract has generated 22 task orders totaling $68.1 million. More recently, the vendor was awarded positions on two mega-vehicles: a $151 billion Missile Defense Agency SHIELD multiple-award IDIQ (December 2025) and a $980 million Air Force Automatic Test Systems Acquisition-I IDIQ (September 2025), both with no set-aside designation. The vendor also holds a GSA Multiple Award Schedule contract (ceiling $7.5 million, May 2022–May 2027) offering 16 labor categories spanning configuration management, program management, integrated logistics support, and technical writing at hourly rates from $82.79 to $209.72, all requiring a bachelor's degree but no security clearances. A $999.999 billion ASTRO platform-services GWAC position awarded November 2021 carries a placeholder ceiling.

Activity has grown from 4 awards in 2022 to 61 in 2024, though 2025 and 2026 show a notable slowdown (38 awards in 2025, only 7 through late May 2026). Forty-six awards face ultimate completion within the next twenty-four months and carry combined potential value of $622.4 million—a significant recompete exposure. By NAICS, the vendor's portfolio is dominated by aircraft manufacturing (399 awards) and other aircraft parts and auxiliary equipment manufacturing (135 awards). By PSC code, miscellaneous aircraft accessories and components (281 awards) and modification of equipment for aircraft components and accessories (138 awards) are primary. The vendor's subcontract footprint is minimal—only 1% of awards are sub-positions—with named primes including The Boeing Company (on Apache and related aerospace support work) and Northrop Grumman Systems Corporation (on machined parts). The vendor also subcontracts to Sikorsky Aircraft Corporation, Bell Textron Inc., Collins Aerospace, Integrated Surveillance and Defense Inc., and smaller component suppliers such as Dulond Tool & Engineering, Aerometals Inc., and The Entwistle Company.

Science And Engineering Services registered in SAM.gov in 2007 and maintains headquarters in Huntsville, Alabama, a strategic location near major Army aviation commands and supportive infrastructure. The parent entity and named subsidiaries all carry identical ownership designations and business structure; corporate organization does not reflect meaningful capability divisions. The vendor's scale and footprint position it as a critical supplier to Army and Navy aviation sustainment and modernization, with demonstrated capacity to execute large-dollar, long-duration modification and production contracts alongside routine component replenishment orders.
