About the company
NGB Corp, doing business as Stellar Technology, manufactures precision instrumentation hardware — pressure transmitters, transducers, temperature sensors, and regulating elements — and sells these components to the Department of Defense and other federal agencies almost exclusively as a prime contractor (79% of recent awards) under small-business set-asides and full-and-open competition. The company is a self-certified small disadvantaged business headquartered in Buffalo, New York, and structured as a for-profit Subchapter S corporation, with manufacturing and distribution operations in Amherst, New York and Buffalo. Stellar Technology's primary NAICS footprint is Other Measuring and Controlling Device Manufacturing (30 awards) and Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables (13 awards); the primary PSC is Pressure, Temperature, and Humidity Measuring and Controlling Instruments (26 awards).
Defense Logistics Agency Aviation dominates Stellar Technology's customer base, accounting for 45 awards and $1.4 million combined potential value — 88% of recent awards across the top five customers. DLA Land and Maritime represents the second-largest customer with 13 awards valued at $44 thousand combined, followed by the Department of the Navy Naval Sea Systems Command (4 awards, $7 thousand), the Department of the Army PEO Ground Combat Systems (4 awards), and NASA Marshall Space Flight Center (3 awards). The single-award Indefinite Delivery Contract with DLA Aviation, valued at $250,000 and running through September 20, 2028, anchors the prime footprint; this IDC covers pressurized transmitters on an as-needed basis and has generated dozens of purchase orders and delivery orders since award on September 21, 2023. Representative recent prime work includes an $89.9 thousand DLA Aviation purchase order (March 27, 2025) for 24 units of pressure transmitters under full-and-open competition, a $94.5 thousand DLA Aviation purchase order (January 23, 2025) for 95 units of pressure transmitters under Total Small Business set-aside, a $63.7 thousand DLA Aviation purchase order (August 20, 2025) for 17 units of pressure transmitters, and a $61.2 thousand Shared Services Center purchase order (July 6, 2026) for transducers for E1 controls at John C. Stennis Space Center under Total Small Business set-aside with completion scheduled for March 10, 2027.
Activity has remained steady across the past five years — 15 awards in 2022, declining to 9 in 2024, then climbing to 17 in 2025 — with 11 awards delivered in the first half of 2026. Over the next twenty-four months, three awards totaling $89 thousand combined potential value reach ultimate completion and face recompete exposure. Stellar Technology's subcontractor footprint spans defense primes including General Dynamics Land Systems (Abrams tank production and upgrade work, January 22, 2026), Lockheed Martin (sensor temperature work, October 3, 2024), Hamilton Sundstrand (pressure transducers, August 14, 2024), and Electric Boat (submarine-related work, June 2022 through November 2023), as well as Columbus Technologies and Services (space flight hardware development support for NASA, July and November 2025). The source does not identify vehicle positions beyond the DLA Aviation IDC; Stellar Technology does not hold seats on government-wide acquisition contracts or multi-award BPAs named in the source. Stellar Technology competes predominantly under Total Small Business set-asides (approximately 30% of awards carry the designation) and full-and-open unrestricted competition; the vendor does not claim 8(a), HUBZone, SDVOSB, WOSB, or other preferential set-aside status.
