Gray Track Propulsion Research Identification 2

U.S. Clandestine Propulsion Portfolio: Identification and Analysis of Emergent "Gray Track" Research Vectors Introduction: The Evolving Clandestine Ecosystem The United States' pursuit of revolutionary aerospace capabilities is a complex, multi-layered portfolio of research and development, deliberately structured to maximize security and hedge technological risk. The established intelligence picture defines a sophisticated architecture comprising at least three distinct but thematically linked tracks. The foundational "black" track is a hardware-focused effort at Lockheed Martin Skunk Works® to develop a mobile power source based on a Field-Reversed Configuration (FRC) Compact Fusion Reactor (CFR), with a credible scientific lineage from Los Alamos National Laboratory (LANL). This core effort is protected by a public-facing "white" track—the NAVAIR "Pais Effect" patents—which functions as a sophisticated instrument of strategic misdirection. An emergent "gray" track, represented by the Un LAB venture led by former Skunk Works® manager Charles Chase, constitutes a next-generation evolution, pursuing a more revolutionary solid-state quantum vacuum propulsion concept under an agile and deniable corporate structure. This report moves beyond this established baseline to identify and profile additional U.S.-based "gray track" entities operating within this clandestine ecosystem. The core methodology is a systematic forensic analysis of the Department of Defense's (Do D) Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) award databases, a primary vector for government-vetted, high-risk technology development. This data mining is followed by a deep-dive investigation into the corporate structures, technical claims, and, most critically, the principal investigators (PIs) of any identified entities of interest. The investigation has yielded several significant findings. First, the analysis has identified and profiled two new high-value entities that fit the "gray track" template: Field Propulsion Technologies, Inc., a recipient of multiple Do D and National Science Foundation (NSF) awards for dual-use metamaterial technology, and Woodruff Scientific, Inc., a specialized plasma physics firm with deep ties to the national laboratory system and a history of Department of Energy (Do E) funding for research directly relevant to the Skunk Works® CFR program. Second, the existence of these parallel efforts reveals a deliberate Do D strategy of cultivating a diversified portfolio of high-risk propulsion concepts. Finally, the investigation has uncovered the first dispositive evidence of a converging professional network among the principals of these "gray" programs, confirming that they are not operating in isolation but are part of a broader, government-cultivated community of practice. Part I: Forensic Analysis of the Federal R&D Funding Landscape Methodology: Mining the SBIR/STTR Database for "Gray Track" Signatures The primary search methodology for this investigation involved a comprehensive query and analysis of the official U.S. government SBIR/STTR awards database (SBIR.gov) and the System for Award Management (SAM.gov). The search focused on identifying patterns and key indicators consistent with the established "gray track" template: a small, agile company led by a credible PI, pursuing revolutionary physics with U.S. government seed funding. The SBIR/STTR program is an ideal vector for identifying such entities. By design, it is a mechanism for the government to fund high-risk, high-reward "deep technology" at the small business level, providing a deniable and flexible alternative to large-scale, bureaucratic programs with prime contractors. The program provides non-dilutive funding, allowing companies to develop proprietary technology without ceding equity or control, making it a perfect vehicle for sensitive or long-term R&D that may have dual-use or national security implications. The search was executed for all awards from 2015 to the present, with results filtered for awards sponsored by key Do D agencies with a known interest in advanced aerospace technologies: the Air Force Research Laboratory (AFRL), the Defense Advanced Research Projects Agency (DARPA), the Office of Naval Research (ONR), and the Missile Defense Agency (MDA). A broad set of keywords derived from the known physics of the clandestine programs was employed, including but not limited to: propellant-less, field propulsion, vacuum energy, zero-point, electrodynamic, metamaterial propulsion, inertial mass reduction, spacetime metric, compact torus, FRC, spheromak, and counter-helicity. Analysis of Search Results: Separating Signal from Noise The initial keyword search produced a high volume of results, the majority of which were determined to be irrelevant "noise" upon closer inspection. The use of acronyms and technical terms across disparate scientific fields creates numerous false positives. For example, a search for "FRC" returned an award to "HARRIS FRC CORPORATION," a company involved in the development of a pharmaceutical compound, not plasma physics. Similarly, a search for "compact torus" identified an award for a "Compact Torus-Shaped Organic Ranking Cycle," a concept related to solar thermal power generation, not fusion energy. A secondary filtering process was therefore required, involving a manual review of all award
