G.s.e. Dynamics, Inc.

G.S.E. Dynamics, Inc., doing business as GSE Dynamics, is a women-owned small business manufacturer of aerospace components and aircraft spare parts for military platforms, competing as a prime contractor on 99% of its federal awards across Defense Logistics Agency, Naval Sea Systems Command, and Air Force programs. The Hauppauge, New York-based company holds SBA Women-Owned Small Business (WOSB) certification and competes predominantly under Total Small Business and Woman-Owned Small Business set-asides, though it also wins full-and-open procurements; it operates Metal Dynamics International Corporation as a subsidiary.

GSE Dynamics manufactures concrete defense components: aircraft structural parts (skins, panels, fairings, doors, beams), hydraulic and fuel tanks, electro-hydraulic-mechanical assemblies, duct assemblies, torque tubes, bell cranks, and fiberglass mast fairings. Recent prime work includes a $6.28 million Total Small Business definitive contract from DLA Aviation (December 2025) for F-16 tail shell assemblies; a $1.76 million firm fixed-price contract (July 2025) for aircraft beams; and a $1.325 million contract (September 2015) for Galaxy C-5 aircraft doors. Naval Sea Systems Command work spans submarine fiberglass fabrication and repair (cost-plus-fixed-fee delivery orders valued $275 thousand to $601 thousand), Low Radar Cross Section Mast (LRCSM) inner mast manufacture ($539 thousand delivery order, September 2025), and periscope/photonics antenna radome production. As a subcontractor, GSE Dynamics performs fabricated structural metal and aircraft manufacturing work for Northrop Grumman Systems Corporation on the E-2D Advanced Hawkeye program.

Customer concentration is severe and heavily weighted toward naval and aviation logistics. DLA Aviation commands 2,833 awards (60% of award count) worth $513.3 million combined potential value; Naval Sea Systems Command places 248 awards worth $2.09 billion—nearly 76% of total portfolio value. DLA Land and Maritime accounts for 256 awards ($26.7 million), and the Air Force Sustainment Center for 51 awards ($14.2 million). The top five agencies account for 97% of combined potential value, with NAVSEA's concentration in higher-value indefinite delivery vehicles (particularly fiberglass mast fairings and submarine systems engineering) anchoring the portfolio.

GSE Dynamics holds a substantial indefinite delivery vehicle (IDV) portfolio. Named vehicles include single-award contracts with DLA Aviation for Lever Assembly Pilot Seat components ($888 thousand, five-year base through March 2031), structural support components ($1.276 million, March 2031), B-52 tail shell assemblies and elevator strip components ($2.5 million ceiling each, November 2030), structural brackets ($2 million, September 2030), and aircraft skins ($2 million, August 2030). Naval Sea Systems Command vehicles include fiberglass mast fairings and support services ($8.94 million, February 2031), LRCSM inner masts ($2.01 million, September 2030), and submarine fiberglass fabrication/repair. The company also participates in a $1.906 billion multiple-award NAVSEA contract for non-critical systems engineering under the CNO Availabilities for Fast Attack Submarines program (Lot 2, through September 2033). Task order activity across these vehicles is steady: DLA Aviation IDV SPE4A222D0014 generated 109 task orders ($19.8 million combined potential value); NAVSEA N6449821D4012 carried 34 orders ($11.6 million).

Activity has remained flat over the past five years—253 to 268 awards annually from 2022 through 2025, with 44 awards in the first four months of 2026. Combined potential value across the 4,727 prime and sub awards totals $2.76 billion; obligated dollars stand at $466.3 million (17% of potential value). A recompete cliff of $62.5 million in combined potential value spans awards completing in the next twenty-four months—248 awards across both DLA and NAVSEA vehicles requiring renewal or recompete.

GSE Dynamics' footprint is concentrated in two primary NAICS and PSC categories: 2,717 awards fall under Other Aircraft Parts and Auxiliary Equipment Manufacturing (NAICS 336413), and 2,806 awards are coded to Airframe Structural Components (PSC 1560). Work is performed at facilities in Hauppauge and Smithtown, New York, with delivery across DLA Distribution depots (San Diego, San Joaquin, Oklahoma, Hill, Warner Robins, Red River, Jacksonville) and Naval Undersea Warfare Center locations. The company has held SAM registration since February 2002, indicating over two decades of continuous federal contracting presence. The award dataset reflects recent activity from October 2025 through April 2026, showing active engagement across small business set-asides and full competition, with a characteristic mix of government first article test contracts, small-dollar task orders under IDVs, and periodic larger definitive contracts for production components.
