Seanair, LLC

Seanair, LLC, a for-profit limited liability company based in Farmingdale, New York, manufactures precision aerospace components for defense applications as a prime contractor (61% of recent awards) and subcontractor, competing predominantly in full-and-open procurements with no socioeconomic set-aside posture. The company is registered as a small business and holds no SBA designations.

Seanair's customer concentration is heavily skewed toward Defense Logistics Agency divisions. The three funding federal agencies account for 100% of awards, with Defense Logistics Agency Land and Maritime leading by potential value at $4.8 million across 22 awards, followed by Defense Logistics Agency Aviation at $594 thousand across 30 awards, and Department of the Air Force Materiel Command Aeronautical Systems Center at 32 awards with no dollar potential specified in the source. The rankings diverge notably: DLA Aviation places many small transactional orders (30 awards) against lower individual values, while DLA Land and Maritime drives most of the dollar volume through fewer but larger delivery orders.

Seanair's prime capability footprint centers on manufacturing bearing plugs, fitting assemblies, sleeve bearings, connecting links, machine bolts, universal joints, valves, and structural hardware such as brackets, beams, and stiffeners — the routine mechanical components that anchor DLA's indefinite delivery contracts. Representative prime awards include a $268.1 thousand delivery order from DLA Land and Maritime in December 2023 for centering bearing plugs, a $219 thousand firm fixed-price purchase order from DLA Land and Maritime in December 2023 for manifold assemblies, and a $178.5 thousand firm fixed-price purchase order from DLA Land and Maritime in April 2024 for universal joints. The company holds six active indefinite delivery contracts valued up to $3.08 million with DLA Aviation and DLA Land and Maritime, with ceiling values ranging from $250 thousand to $3.08 million and ultimate completion dates extending through October 2026 and January 2028.

Activity has expanded significantly — seven awards in 2022 to 39 in 2024 — though 2025 slowed to ten awards and only one award is recorded for 2026. Only two awards with combined potential value of $203 thousand reach ultimate completion within the next twenty-four months, placing minimal recompete pressure in that window. All work is performed at Seanair's facility in Farmingdale, New York; one award notes performance in Lindenhurst, New York.

Seanair's subcontractor footprint is anchored almost entirely to Lockheed Martin, where it supplies fitting assemblies, beams, brackets, stiffeners, and related structural components for C-130J aircraft programs spanning Multiyear III procurement, Five Year Ordering Contract (FYOC) phases, and the Combined Aircraft Delivery Development Integration and Engineering (CADDIE) program. Sub awards to Lockheed Martin run from December 2022 through February 2025 and span airframe components (fitting assemblies, beam assemblies, bracket assemblies, stiffeners, bellcranks, and cargo door locks) supporting congressional add aircraft and incremental funding initiatives. A single sub award to Derco Aerospace, Inc. in July 2025 covered aircraft spare sector manufacture. Seanair's subcontractor role is characterized as fitting and structural assembly manufacturing for fixed-price delivery orders issued on an episodic basis rather than under a standing subcontract vehicle.

Top parent vehicles show concentration on five DLA and Air Force indefinite delivery contracts. The Defense Logistics Agency Aviation single-award IDC FA862520D3000 anchors 29 task orders with no specified combined value. The Defense Logistics Agency Land and Maritime single-award IDC SPE7MX22D0001 carries 6 task orders and $1.3 million in combined potential value. Two additional DLA indefinite delivery contracts (SPE4A623D5490 and SPE4A724D5311) and one Air Force IDC (FA862516D6458) round out active vehicles with smaller order volumes. Award category concentration reflects the hardware focus: Aircraft Manufacturing leads with 32 awards, followed by Bolt, Nut, Screw, Rivet, and Washer Manufacturing with 12 awards, and Other Aircraft Parts and Auxiliary Equipment Manufacturing with 10 awards.
