Stumptown Research & Development, LLC

Stumptown Research & Development, LLC, a small business based in Black Mountain, North Carolina, designs, fabricates, and maintains specialized blast simulation equipment and related scientific instrumentation for federal military research institutions as a prime contractor (89% of recent awards) and as an occasional subcontractor. The company is a for-profit limited liability company competing on full-and-open procurements without set-aside designation.

Stumptown's capability portfolio centers on the design and fabrication of advanced blast load simulators (ABLS) — precision test rigs with internal cross sections, pressurized driver systems, measurement instrumentation, and data acquisition systems — along with repair, maintenance, and engineering support for existing simulator assets. Representative prime work includes a $486 thousand purchase order from the Veterans Integrated Service Network 1 (VA) awarded June 8, 2026, for design and fabrication of an Advanced Blast Simulator featuring a 24-inch by 24-inch test section, dual-mode driver, and three pressure sensors, with installation and operational training; a $139 thousand definitive contract from the Department of the Army Medical Command (May 2022) for design, fabrication, and delivery of a compressed gas-driven advanced blast simulator for the Walter Reed Army Institute of Research; and a $31 thousand purchase order from the Uniformed Services University of the Health Sciences (February 2026) for design, fabrication, and installation of an ABLS transition-section repair. Stumptown also holds a $1 million indefinite-delivery single-award contract with the Army Corps of Engineers Engineer Research and Development Center (awarded February 2026, extending through February 2031) for preventive maintenance and engineering support services on the ABLS at ERDC's Vicksburg, Mississippi facility, and a $568 thousand Other Transaction IDV awarded September 2022 to retrofit an existing Blast Load Simulator and develop a Virtual Blast Load Simulator.

Customer concentration is skewed toward the Army Corps of Engineers research enterprise. The top five customers (by combined potential value) account for 100% of awards: the Army Corps of Engineers Engineer Research and Development Center anchors the portfolio with three awards ($1.6 million combined potential value), followed by the Veterans Integrated Service Network 1 ($486 thousand), Veterans Integrated Service Network 23 ($141 thousand), the Army Medical Command ($139 thousand), and the Uniformed Services University of the Health Sciences ($48 thousand). Activity shows growth in 2026, with four awards issued year-to-date, compared to one or two annually in prior years. Two awards (combined potential value $525 thousand) reach ultimate completion within the next twenty-four months and face recompete exposure. Stumptown's sub footprint is minimal: one sub award issued January 4, 2024, as part of ManTech TSG-2 Joint Venture for fabrication of TAC-clamp assemblies and channel extrusion supporting Marine Corps Intelligence, Surveillance, and Reconnaissance cyber operations and technology innovation work. Work is performed at the vendor's Black Mountain headquarters, at ERDC facilities in Vicksburg, and at customer locations including the VA in White River Junction, Vermont and the Army's Walter Reed facility in Silver Spring, Maryland.
