Low-Volatility, Reduced-Toxicity Hypergolic Propellants

The Missile Defense Agency is seeking innovative hypergolic propellants with significantly lower volatility and toxicity than current formulations while preserving the rapid, reliable ignition critical for missile defense applications. Traditional hypergolic fuels, though effective in ignition delay and specific impulse, pose substantial safety and handling risks due to high vapor pressure and extreme toxicity; this program aims to replace them with safer alternatives that maintain or improve performance across operational temperature ranges. Candidates include ionic liquids, reaction-driven amines, boranes, and custom blends, provided they demonstrate miscibility, stable performance, and reduced environmental and personnel hazards without compromising responsiveness in mission-critical scenarios. This solicitation, titled Low-Volatility, Reduced-Toxicity Hypergolic Propellants under MD A26TZ04-NV003, is a Small Business Set-Aside, restricted to businesses with fewer than 500 employees as mandated by the SBIR/STTR program. The opportunity was posted on July 1, 2026, with proposals due by July 22, 2026, and is administered by the Department of Defense. Solutions must be cost-effective, scalable, and capable of integration into existing DACS systems, with a focus on long-term operational safety and reliability. No place of performance or point of contact details are specified, and the primary reference is through the SBIR website link provided.
