What GSE Dynamics does

GSE Dynamics, Inc. is a privately held, vertically integrated defense manufacturer founded in April 1971 by former Grumman Aerospace structural engineer Daniel J. Shybunko. Headquartered in Hauppauge, New York, the company designs, machines, fabricates composites, welds, finishes, assembles and tests complex mechanical and structural components and assemblies for the U.S. Department of Defense (Air Force, Navy, Army) and major aerospace primes including Boeing, Northrop Grumman, Lockheed Martin, General Dynamics, and Sikorsky. Operations are split across two facilities totaling 87,000 square feet: a 30,000 sq ft main manufacturing and engineering campus at 25 Corporate Drive and a 57,000 sq ft specialized composites plant at 110 Oser Ave operated under the GSE Composites trade name.

The company's core technology stack centers on CAD/CAM-driven precision machining using 5-axis CNC centers (Mitsui Seiki HU63A-5X, Thermwood M77-510, HAAS UMC-750SS), AS9100 Rev. D:2016/ISO 9001:2015 quality management, NADCAP-certified composite manufacturing (BondTech autoclaves, resin infusion, pre-preg cure, sandwich and metal-to-metal adhesive bonding), AWS D17.1/D17.2 Mil-Spec welding across exotic alloys (Inconel, CRES, titanium, stainless), Boeing Digital Product Definition (D6-51991) qualification, and CMMC 2.0/NIST SP 800-171 cybersecurity alignment. Capability extends to painting and CARC finishing, in-house acceptance testing, and engineering/program management across the full component lifecycle.

Revenue is generated through competitive U.S. defense prime contracts and subcontracts on tier 1 and tier 2 aerospace programs; an $18.9 million U.S. Navy contract for composite submarine mast fairings (Trident, Sea Wolf, Los Angeles classes) is a flagship program. The company holds federally certified Woman Owned Small Business (WOSB) status with the Defense Logistics Agency for Aviation and is wholly owned and CEO-led by Anne D. Shybunko-Moore, who joined in 2001 and grew the business from $4-5 million in sales to over $15 million by 2016.
